/wt/ watch thread: Sturmanskie edition
This thread is about the appreciation of watches, as well as the micro-engineering and materials engineering that is required to make a fine watch.
Required viewing for newbies:
Previous thread >>52396214
Two fucking threads again. Since this one has the standard OP, and it was made first I vote for this to be the one we stay with.
so apparently this is the proper watch thread
This is all dogs hit. How can you live with yourselves? That shitty dial 420blazeit Omega from yesterday looked better than these so called watches.
Boy i ended up shitposting so hard last thread i actually fell asleep.
It's a Miyota 90XX series right?
first time posting here, it's seen some shit in 5 years with me... Oh and i don't bother setting the proper date anymore
I like the looks as well, and as much as the Miyota doesn't quite justify that price (Despite being a good movement) i think you did fine.
It's a microbrand after all, you get excellent QC and a unique design.
I really wouldn't call it ugly, far from it reall.
It has a nice neutral tool watch look, which keeps the iconic Seiko deiver design. Though it does need a proper choice of strap, or else it looks a bit bland.
I immensely regret the 25$ i spent on this bracelet. It's a solid link and it's comfy, but it looks awful on the wrist.
I'm somewhat considering getting an aftermarket Oyster.
What does /wt/ think of Omegas olympic bullhead?
pic not mine of course.
I love mine, it's a unique watch with a pretty cool history and interesting looks.
I like them. I've been meaning to get my hands on a Citizen bullhead but I'm still researching 'em.
How's that fabric strap going for you? I use mine when not at a desk as it digs in to my wrist a little when typing. Otherwise it's comfy as fuck.
I'm more into the Seiko 6138 Bullhead.
Used to be high-tech all-American brand, now owned by Citizen, mostly producing boring high-frequency quartz shit. They live off the old fame so sometimes they'll make a nice homage of an old design.
The 57,600bph sweep and high accuracy of the Precisionist is neat I guess, but probably not worth the rate it eats batteries.
They're now making a re-edition of their moonwatch which looks kinda neat.
>They're now making a re-edition of their moonwatch which looks kinda neat.
Except they totally fucking ruined it by making it gigantic and using a fucked up chrono movement. One would think a precisionist would make an excellent chronograph with the sweep but it ticks the seconds off and has a tenth second subdial instead for some idiot reason.
Apparently not. The way most mechanical chronograph movements work is the watch is running then power is taken off and partly diverted to the chronograph wheels, so it's not good in the long run to have those running permanently, so it's like adding load. Seikos I believe have a friction clutch. Equivalent of holding in the clutch pedal on a car to make the engine not drive the wheels, instead of being able to put it into neutral.
This guy explains it better than me. The Seiko chronos are "fine" if you keep the chronograph part running permanently, and then stop and reset when you need to use it, but the risk of the spring deforming or breaking is still there every time you reset it.
Consider this guide too for the equivalent from Citizen, plenty of models from both companies, although the Citizen doesn't have that clutch issue that Seikos do.
So as a proof of concept I used a q-tip and Brasso and managed to scrub off the daniel wellington text on an old busted aliexpress special. Works well - don't rub places that have already had the text rubbed off in case it goes to bare metal and use masking tape to protect the dial. Unfortunately the area becomes shinier than the rest of the dial & in exactly perfect light you can see a small imprint of the text. Inside a watch I doubt you'd see it.
Good if you want to build yourself an extremely simple watch with no text, 36mm and just 2 hands.
>Tfw your WIS 4chan bud gives you a diver for daily use/swimming at Daytona Beach
We /blazeit/ now
Thanks Taylor :'^)
>extremely smooth sweep chrono
>extremely accurate (few seconds a year)
>Bulova provenance, real moon watch
>comes with a strap so you can be the maaaan on the moooooooon
Just get an old tuning fork watch, we all know it's what you really want, modern bulova is Costco fodder
My sides were destroyed when I saw a couple of Omegas in the cabinet next to the shitty diamond rings.
Don't know why they'd cheapen the brand like that.
Let's face it, how many people are even going to use the chrono functions? I don't think it's too horrible if you can get it for a good sicount off RRP
Can someone tell me how this would work
>spring drive watch uses electro magnet system to slow down a mechanical movement
What happens to the escapement? Would it just furiously unwind the mainspring because there's nothing braking the spring from unwinding anymore?
Ah, had to look up an image of the movement system, electricity generated by a glide wheel from the mainspring. So the hand would stop as soon as the mainspring runs out of energy
I had previously assumed it was a separate entire quartz movement regulating the mechanical one
Why aren't pie pan dials more popular ? Shit's gorgeous
I fell in love with this absolute beauty of a rep. It has a hand wind Lemania mechanical movement with a beautiful sweep. Only problem is I cant find the Gen model of it anywhere. Anyone know?
Eh. It said in the description. Either way, its a beautiful watch with a great movement. Id just like to know the model, or if its another design from a rep maker with the PP name stamped on it
Yeah the ST-19 is a decent movement for sure. Shitty pic related is the movement in my Seagull 1963.
Its a beautiful movement for sure, but how reliable is it? Ever skip? How smooth? Sorry for the bombardment but ive never had a seagull
I recently got some old watches from my grandfather, since I have no clue at all I'd hope you guys could help me out. If any are worth anything for a collector or I should hang on to them?
I had a stuttering chronograph seconds hand but that was fixed for free by the guy I got this from. Since then zero issues whatsoever, and runs within a few seconds a day. Mine was just an exception as very few people in the thread seemed to have problems.
Mine was $230 plus shipping from HK from the WUS project thread thing in late 2014.
>tfw only got a blurry shot a split second before the little fucker jumped me for having a camera in his face
Dogs hate technology.
Any classic Amphibia and most SE Amphibias. I'm a bit biased towards the 710 Ministry-case.
420 case is the smallest and the most bare minimal, basically just the case wrapped around the movement with four lugs sticking out. But the 710 isn't that much bigger at all, it almost fits the same box (39x46 vs. 41x45), just with more case material. What are really noticeably larger are the 110 and 090 cases.
got more, can you rate them too?
its maurice lacroix, sorry for the shitty picture.
The terrorist Casio is an extremely low-tech, some plastic + PCB + some electronics in a $10 watch, so it's easy to manufacture a $10 fake. The Amphibia on the other hand is still a complex machine with mostly steel and brass parts. The only reason that they're still so cheap is Russian wages, half a century old commie manufacturing tools that refuse to die and that Vostok hasn't spent a ruble on any meaningful R&D since probably the 1980's. Pic related, a USSR Neptune, you though those were a new thing too?
POST COMFY WATCH VIDEOS
All the current precisionist chronos have a third button to switch between sweeping running seconds and chrono mode where it moves to zero and then starts ticking while the .1 seconds are counted on the subdial. You can play with a simulated one on their website. I don't know if the moon one will have that third button or not but the tenth second subdial says to me it will still tick.
I rike it. What's the stuff he uses to polish the links and is there an example of someone doing it to the center links too? All the other videos of refinishing are amateurs with scotch brite and dremels
I looked at all the chronos on their website, they all have that third button and switch between sweeping running seconds and ticking chrono seconds. There were no chronographs in that video you posted, what Sea King are you talking about?
thrift shop anon here
today was a good day
Snagged a memewatch for $50, brand new.
Ditched the ugly white silicone band for what's probably an uglier nato, but the lugs are too short to strap it properly. Wat do?
The Strela 3017 was the first chronograph in open space. The Poljot Sturmanskie 31659 (in the OP) was used in space and was military-issued only. Poljot Okeah 3133 was also in space, same military-issue as the 31659.
More are listed here.
just bought pic related. happy with the look.
honest question: what is the casio g shock's reputation? i see them online in wild colors and stuff but only ever see military type dudes wearing black ones irl.
Theyre tough as shit and cheap as dirt. The black ones are for use, nothing else. Theyre ugly but some of the most useful pieces for hard work, swimming, even diving, and general fuck-em-up situations. Thats why i have one
No real cosmonaut watch ever had big fat red stars and such on their dial, that's kinda silly. Same as how there was no flag, eagle or hamburger on Apollo Speedmasters. What might work for you are the commemorative civilian watches.
Gshocks are rugged like they claim to be, and for a fair price for the most part.
The colorful ones aren't popular among military types for a fair two reasons. They are tacky and standout.
They are tools, and many people especially "watch people", find their looks less than appealing, though some find them utilitarian looking and like that kind of thing.
The rangeman's extra sensors intrigue me. The way I see it, if I'm going to wear a digital watch it should have some kind of interesting and useful function
I have a friend that has pic related.
Sometimes I want to ask him if I could waer it for a day,it looks fun and fresh.
I'd normally say you got cucked hard, but that transparent watch is actually kinda neat. Kinda like those old game boys.
Found something similar on eBay. It is Soviet but made for the export market.
Here's another thread about these.
Yap, that's a hit! I will have to check in tomorrow what model it actually is, though I am not in ownership of a box or passport. But it runs perfectly and is in better condition than the one on ebay.
i have that watch and have been wearing it every day for years. best money i've ever spent, i use it all the fuckign time
you need to take yours apart, get some naphtha and a q-tip, and rub that white lettering off, it'll look nicer
i left everything but the "10 year battery" and "5 alarms"
Why not paragraphs of text? I fuckin love tiny writing
You changed crystal too right?
But you're not the other guy with the dagaz dial and cousins uk.
I kind of want a sterile snowflake mod, but I don't want to pay someone more than the watch for someone to remove all the inshicta branding and mod it, but tools would cost as much as the watch and I'm unsure about modding. Practicing on a Bagel / Soki wouldn't really work either as even from Rafflestime dial and hands costs almost $50.
This is actually pretty much the same cousinsuk crystal that guy has
Tiger concept sell pretty faithful homages to a lot of obscure rolexes/tudors. Considered just buying one outright?
You guys must really like black rubber and plastic
If this came non-gilt, sterile in black or blue and preferably with snowflake dial, I'd get it.
Even if the 9015 version is $215 without shipping.
Don't care much for having another explorer dial 36mm oystercase watch and while the 5513 looks nice I don't really like the merc hands..
I guess I should just buy some tools and make a hobby out of turning Bagelsubs into snowflakes and 5517 / 6200s.
It tells time moderately clearly.
If that's watch you want in a watch, good on you.
But that's a black bay, not a vintage snowflake..
It's pretty kek that there's a rep of the Black Bay Only Watch piece unique.
Have this thing for over a year now. Are you guys mirin' my technology?
has anyone got experience with purchasing from Global Rakuten ? I want to pull the trigger on pic related, but I live in europe and it seems like it would be easier to just have the watch ship from japan
Get un-lazy, m8. Have a cat for motivation.
The model on the left is a Snowflake. Likely a MN (French Milsub) model.
Backlight and lume is a neat combination.
Does the backlight replenish the lume?
Timex manages to incorporate it in the crown though.
>Seiko can't into monopusher watchlighting
Speaking of watch lighting there's this: https://www.youtube.com/watch?v=S71wN5st9Oo
>Does the backlight replenish the lume?
No it doesn't because it super weak. You rarely have to use it though because if it's dark enough that you can't see the watch then you can see the lume on the watch fingers and next to the timers.
Invictas are decent for modding, but you stated the problem right there. The branding. Just build your own watch, get your own sub style case, crown, bracelet, movement, etc, and put a fitting dial in that
an invicta? caseback wrench, hand remover, tweezers, small flat screwdriver and either a hand setter or a steady pair of hands.
crystal press and nylon hammer for changing crystal
Just ordered this overpriced piece of shit instead of getting a real watch. Will post tomorrow with some 1337 riced out shit.
Simple watch would be a 6497 + case and hands from either Parnis or Ofrei + Crystal and gaskets, crown, movement holder, stem and whatever else from Cousins UK / Ofrei.
I know Ofrei has kits as well and I think there's some chink special kits (mainly Fleigers / Panerai homages) on Ebay.
Seiyajapan is good and reliable. From what I've heard Rakuten's buyer protections are nowhere near like what ebay has and if you get fucked over then you're fucked and that's that so make sure you find a good seller if you use that site.
I'd say to just go for it.
I read a load of forums and guides of people's 8926ob mods before I even bought the watch, I was a total novice but it really wasn't that hard to mod. You just need to take it slowly (mine took around a month, I only worked on it when I had plenty of time free) and have patience.
The cost of tools really wasn't an issue, I used a £5 set off Amazon, a cheap plastic movement holder, and needle files that my Dad had. I even initially changed the crystal using just the nylon hammer that came in the tool set. The biggest cost was the Dagaz dial and hands, and the bezel insert, they cost almost as much as the watch.
Best mod guide to start with is http://www.stefanv.com/watches/black-lagoon-an-homage-to-the-tudor-heritage-black-bay.html
>mfw waiting for my new watch in the mail
>mfw my other package detonated in my hand and glass flew everywhere
Buy a AP Millenary rep instead
Was this your package, Akari?
>fake tourbillon-style exposed balance wheel
So I guess Fossil is now also ripping off those awful Millenary style watches? There's some other watch that looks almost exactly like that Fossil, but I don't remember what it is right now, it may not have been an AP.
No that's Nick.
Who are you?
I prefer the snowflake dial to the 9724, but this kills the historical accuracy..
This would would be a bond big crown sub whatever ref that'd be if it had the normal dial.
I've dropped something new on the Pebble Store, not really a massive undertaking but still something that I'd like you guys to check out.
Searching "metal gear" should bring it up.
About to get a Vostok Amphibia, but I'm facing some choices.
I'm trying to decide between either the blue or black scuba dude dials as well as, for a replacement strap, either a black and grey or the correct black, olive, and red James Bond NATO.
I'm trying for something that looks good with both casual, daily wear and won't look out of place with professional attire.
raging about leather on amphibias is ridicuous to be frank
the design isn't the most generic diver one, looks very similar to non-diver komandirskies and so on, and in general fits pretty nicely
leather can even be water resistant!
so yeah, I can understand whining when it comes to submariners and so on (I agree there the leather doesn't look very good), but with these ruskies, i don't get it
My Swiss watch collection is almost non-existent (1 swiss left) and I feel like rebuilding with a new movement after I purge some watches I own
My current watches in my collection (if you could call it that)
1st)Vintage Day-Date II homage Seiko quartz (really fucked up condition)
2nd) Rolex Air King which I'm going to sell within the next week
Although I love my Air King I feel like it doesn't belong in my collection anymore since my tastes in watches has drastically changed and although 34mm is real nice I feel like 38-42mm is better for me
So after I sell my Seiko Quartz/ Air King I'll be getting 3 watches, 2 which are currently undecided
On the way I have an Bulova Accutron Alpha II which just caught me by surprise (I don't look up Bulova often and was stumped when I saw this was released in 2014) Also UHF precisionist movement? Looked pretty damn good to me
After researching for the past 2 days on some nice smooth movement watches I came across Grand Seiko SBGA127 Spring Drive which would be perfect addition to my new watch collection, but also reading that Seiko doesn't really service a GS watch after 10 years or after loss of parts annoys me. It could be different for some models but I'm still not 100% sure since this is a fairly new model and I'd have to get in touch with Seiko to verify
My second choice on my list is a Bulova Accutron II Surveyor
It's very minimal and could make for the usual beater
I feel like the Spring Drive GS and Ultra High Frequency watches will be a game changer for me. Feel free to give me some recommendations fellow /wt/ enthusiasts as I haven't pulled the trigger on anything yet. All of these watches would be the first brand new ones I buy since all my past ones have been bought used which isn't bad but I just want to get that good feeling of buying and unboxing a new watch
It's been mentioned before, but seiko has said they'll keep replacement parts for a movement 20 years after it's been discontinued (which is actually the same as swiss makers). Considering the spring drive is their crowl jewel of a movement, I don't see it being discontinued for a while.
Also, if you want a smooth sweep & an interesting movement, look at the tuning fork watches. The old accutrons, omega f300's, & the omega megasonics.
Good to hear that, makes it feel more comfy about getting one
Haha I'm the other anon from last night anon, I have looked into the Omega Seamaster megasonics which are quite nice but I haven't looked into how available parts are for it and how much servicing one costs yet but it's definitely on my list. Mentioning the Accutron, I have owned the older spaceview Accutron it was a hand me down from my dad but when I saw him sporting a non-brand quartz watch I just gave it back to him fully serviced with a new band and everything which was a real good feeling since he had forgotten completely about it.
I'm sure you could find some watchmakers who can service tuning fork watches (especially since it's an omega).
I'd like a megasonic myself, if only this specific case/dial combination wasn't so hard to find.
I'm pretty satisfied with the fabric strap, it's like a common nato strap but comfier, I forgot sometimes I'm wearing a watch desu.
>tfw no white cosmonaut strap for my Sturmanskie
Are there any cool things in it?
Someone asks the same question every couple days. If you can't see how having a watch is more convenient than taking your phone out from your pocket every time you want to check the time, then don't get a watch.
yes, it gives you the specs to make your own minus the teflon beta cloth which is impossible to find. Also some of them had their serials marked with a typewriter and some with rubber stamps and marking ink. That ink is hazmat and probably only required because the cloth is teflon and the cloth is teflon coated glass fibre because of the apollo 1 fire
Are JLC Super-Compressor style watches actually SC-s?
Looks like I was wrong about the Bulova moonwatch, chrono seconds are smooth sweep but running are not. Maybe I will yet pick one up.
So is there some sort of explanation for why PP uses the cross of the Order of Calavatra and VC uses the cross of the Knights Hospitaller? Is it some sort of illuminati bullshit or did they just both decide they were neat symbols (they are) or what?
Yeah it is. I'm just going to batch these up to save time and space.
Paid $12 for it. Had to do shenanigans to actually get it.
Most likely VC had some connections with the masons, VC was founded 1755 after all.
I don't know the connection between Calatrava and Patek.
It is incredibly comfy. And since i got mine i'm not wearing anything else. Have several mechanical watches but now wear this 24/7.
It's also so pleasant to look at, i don't know what it is, prob. right proportions and the smaller size.
"The reasons that prompted Jean-Adrien Philippe and his partners at the time (Antoine Norbert de Patek had meanwhile passed) to adopt the Calatrava Cross are not known. Quite likely, it was the pleasing form of the cross with four fleur-de-lis, which are considered to be symbols of French royalty and can also be found on the coat of arms of the village in which Jean-Adrien Philippe was born."
From Patek Philippes website.
That thing is possesed with some vodo shit from casio.
Srsly, i never seen anybody hating it. All my friends like this one the most and never has anybody said anything negative when somebody posts this model here.
I found my exit watch, i guess.
No my child, but with love in our hearts and casios on our wrists, his blessings will go out to the world and open us the gateway to the holy father.
This is just a regular rolex with small alterations, which watch collectors will furiously fap about for years.
it looks better than the modern rolex dial, but in the end it's nothing special to the eye, that i would desire. For 25K that thing will be sitting in banksafes for decades. So there is really no point in this watch.
My point was literally to compare it to all modern Rolexes or any newer Sub.
Ah, ok. Well yeah, i also like the older subs more than the fugly new shit they have.
They have the new oyster perpetual now, the 36mm version looks so good. That would be the only modern rolex i'd buy. But i am the guy who was drooling over his casio MQ24, so i doubt that i would ever spend so much on a watch.
He wears now a swatch, read an article that the casio became hard to read at his age.
Since he got the casio molesting has increased by 100% so
reporting for duty. Do the NATO bands look any good on these things? The band on it right now makes my wrist all nasty
Also, recently discovered that casio has colored models on the base of the mq24 version.
Gee casio, thank you. And people complained about gaben raping their wallets.
Someone should write him an autistic letter, like how /g/ used to pester rms with inane emails.
Do you mean the normal version of this rare date version of the 116000?
Or one of those boring flat dials?
Funny thing is that you can buy a rep of the HS01 (http://www.projectxdesigns.com/watches/hs01/) for like $160.
Other notable modifications is this modern daytona Newman.http://www.projectxdesigns.com/watches/ds7/
This one with the double indices at 3,6,9
I like the right one. It's the modern rolex that is pleasant to look at. But no way i am buying this later in my life. I just like that rolex goes the trend and offers smaller versions, something fresh after seeing the 1000th 45mm+ watch.
Can anyone help me ID this accutron? It was made in 1972.
What battery should be used with this watch? I read that this (www.amazon.com/Renata-387S-Silver-Oxide-Battery/dp/B0007ZA8SW/) works but runs fast. Is that true? Is there a better battery to use?
I don't recommend putting Lithium battery in watches since they tend to leak and fuck up the watch I've never heard of that battery brand neither so like they say if it's too good to be true stay away
Ultra is a company that makes computer hardware.
But thanks for the info. I thought all batteries in class were created relatively equal. Had no idea there could be potential hazard by variance.
it's actually not particularly great for most boards. You can't scroll through a thread's posts, only reading them one by one, but it's good for checking a thread while doing other things.
If someone say, provides directions for something, you can pull that post up on your wrist and have it for reference.
NATOs can't be strapped properly, as the Pebble's lugs are too short to fit two straps thru one springbar. However, you can just string it through the lugs singly, and the low bar clearance is enough to keep the watch in the proper position.
I would suggest taking the rubber keeper loop off the stock Pebble band to secure the end of the NATO strap as well, since without the fold, there's nowhere to tuck the end.
They didn't think it looks good, nobody thinks that except delusional idiots who spend 10 grand on a watch and then claim that it's ok because you can barely see it anyway if you look at the watch from head on and it's not that big a deal anyway I swear it's perfect I love muh maxicase shiny blingy ceramic bezel abortion of a Submariner. For some reason Rolex decided it would be a good idea to intentionally shit up their watches just to make it harder to fake them, it's retarded.
But i also hate that shit. Makes the watch pretty trashy.
Rolex has so much money, why don't they just find a way to hide the brandings to the backside. If i wore a rolex, i wouldn't give a flying fuck if somebody called it fake. My friends won't and strangers also don't hate me and start raging about my watch. There is no fucking logic in the security bullshit on the dial.
It makes me so angry.
And I know the reason why for all this fattening up of the models that have done fine for fucking ages:
Manlets in the east, the only ones buying this shit up in such volume, need massive watches ironically compared to yurpeans some of whom would really benefit from a proportionally sized watch.
They need them to be big, because chinaman john with big ridiculous clock on hand means he's richer than other chinaman joe for small watch or no watch.
Sacrificing long standing principles to appease chinks and arabs makes me lose a lot of respect for rolex.
Such a shame.
They produce over one million watches a year. They may be one million very good watch-nerd approved watches, but still Rolex is not some niche little company in it to make the very best watches they can make purely for the love of watchmaking. They're an enormous fucking company that has to do a lot of mass production to stay afloat and if the tasteless chinks want huge ugly shiny bezel maxicase abominations and they're the only ones spending thousands of dollars on a watch then by god Rolex is going to make whatever the hell those people want.
Rolex is a shitpile and just a moneyprinting machine, like everything that has originated from that robot country, switzercuckland.
Fuck the gooks and their tasteless bs. I hope that nation wipes itself out fast.
Rolex has enough money to produce for the white market, they only max out their income to cater to investors.
Every sane white man with money knows not to waste his shit on pointless nigger bling, like the "luxury" watches meme.
>they only max out their income to cater to investors.
Actually Rolex don't have to cater to any investors.
They have none.
Rolex isn't a publicly shared, NOR private company.
It's a charity.
Forgot my image.
Just got my Accutron II Alpha, gotta say it's feeling real good so far, only thing that irks me is this shitty leather butterfly clasp + mineral glass but other than that it looks real good would give it a 8/10 so far but once I get the leather band problem fixed it'll easily be a 10/10 might get it relumed too with a stronger variant since this one looks pretty weak and will probably wait for sapphire glass face to come engraved with its Bulova name
An old well worn Seamaster 2000 from the 80s, quartz yes but still pretty in my eyes :).
Well, my favorite little aussie managed to find a Seiko Kingpenis in mint condition with a paper like dial. He still has a few more watches en-route. Including a Seiko LM special with a white dial.
I'm really tempted by it, and if i won't have it it'll be up for sale soon.
Day wheel coloring is a bit off though, but that's apparently factory made.
Maybe +/- 10 s/yr if you keep it indoors and never go outside where the temperature might deviate more than a couple of degrees from room temperature and ruin all their carefully rigged accuracy tests.
Also this is neat if you want to learn about quartz oscillators beyond the ones used in wristwatches http://www.4timing.com/techcrystal.htm
>The requirements of quartz resonators for wristwatch are: small size, low power dissipation (including the oscillator), low cost, and high stability (temperature, aging, shock, attitude). These requirements can be met with 32.768 kHz quartz turning fork resonators. It is interesting to know that 32768 = 215 or 1 Hz = 32768/215. In an analog watch, a stepping motor receives one impulse per second which advances the second pin by 6, i.e., 1/60th of a circle every second. The 32.768 kHz is a compromise among size, power requirement (i.e., batter life) and stability.
>Quartz wristwatches are sufficiently accurate, usually, while worn as intended, i.e., on the wrist for ~16 h and off the wrist for ~8 h each day. The accuracies degrade when the watch is off the wrist for extended periods. The further the storage temperature is from the optimum temperature, the faster the watch loses time. At temperature extremes, e.g., in a freezer at - 55°C, or at the temperature of boiling water, wristwatches lose about 20 s per day.
>The angle of cut of the resonator used in wristwatches is such that the zero temperature coefficient is at ~ 25°C, as shown in the following f – T curve. This has been found to provide the highest probability of accuracy, based on the typical durations and temperatures while the watch is on the wrist and while it is off the wrist.
What does /g/ think asbout BERING watches?
Especially their solar watches.
