Hello all,

I generally hang in the halls of the Russian (F10) forum, but since you guys are the diver specialists I felt compelled to post here, as well.
This may be photo heavy, and for that I apologize. I have made them as small as Windows will allow.
Here is what I know:
Soviet diver. Made at 1st Moscow Watch Factory (according to numbers matching passport/paperwork) and released or certified (not sure which) 24 MAR 1976
It is big and heavy. .Solid body with screw-down crystal retaining ring and very thick flat glass. Canteen crown cover with internal gasket. Only marks on the dial are a triangle flanked by 2 dots. Case back is marked on by the case number and the Soviet Mark of Quality.
The red lume at 12 o'clock is visible on camera, but not to the naked eye.
Have not figured how to get the crown out of the case. Not sure if it has a screw or push-button keeper or even a lever. Since I have never seen another like it, I don't want to poke and prod until I receive good information.

Thanks in advance for any insight anyone is able to provide.

Now for the photos:

That's a pilot. No clue of provenance but I'm sure you'll never meet anyone out in the wild with another one. Really cool.

Huh..... never thought of it being a pilot. The paperwork calls it a dive watch... but....
It is waterproof to 3kg/cm2. What is the ATM equivalent of 3kg/cm2? Is it something like 100 meters? It is built like a tank - overkill for a lousy 100 meters (if that is what it is). So the pressures of flight may be the ticket.

Looks like tritium lume to me....the small vials that are intact glow nicely and the broken ones are dead.

I'd like to see a pic of the crown assembly from the side. Looks like a sort of screw down "cap" is missing on the crown where you can see threads. See a Invicta Russian Diver for a lousy attempt at this.

Cool piece, a sure discussion starter!

Cheers

EDIT: Found this interesting article

http://www.uniquewatchguide.com/russian-diver-watch/

Think it is similar to the 1st one (not the Invicta RD ...)!

Thanks smille76 - here is your requested photo (cap on and cap off). I took the canteen cap off to photograph the crown.
A little digging on Google leads me to 3 ATM=20/30 meters, depending on whose answer you trust. With such a massive case (260g) it must be built for flight or seriously over engineered for such a puny depth.

Hi,

I'm pretty sure this is a dive watch and someone modded it at some point with a flieger-type dial. The size and bulk have nothing to do with actual WR. Some watches built nowadays have high WR and keep a thin and sleek profile (check out Limes 1Tausend for example).

If the build tolerances are average at best, even if the watch is huge and bulky, it will still leak.

They still make some apparently, as found on my article I shared before and I think that it is pretty cool.

Cheers!

3kg / cm2 is roughly 40psi if my head maths works.

Long time since I was in school so some engineer or knowledgeable person please, please,correct me but I reckon 3kg/cm2 is about 3bar pressure which is the gauge pressure at 30 metres under water.

Convert to Newtons as standard unit of force, multiply mass by gravity: 3kg X 9.81 = 29.43N

So 29.43N for every cm2. Standard unit of area is the metre squared, there are 10,000 cm2 in 1m2 so 29.43 X 10,000 = 294,300N/m2

Normally you'll see watch depth ratings written directly on them but some say ATM (atmospheres) or some might say Bar

1N/m2 - 0.00001 Bar, so our 294,300N/m2 X 0.00001 = 2.943 Bar pressure

Lets call it 3 Bar, that's 30 metres under water. (30m under water is a total pressure outside of 4Bar/4ATM but there's 1Bar/1ATM inside the watch so the difference between inside and outside is 3Bar/3ATM)

At that rate it could be a pilot after all, even with the diver's canteen crown? (All we need now is someone that can actually do the maths correctly! LOL)

Dead on. My 40psi was off by 2psi.

 

[duffhessian1776]

So my suspicions are correct, as are those of others, that this belongs in a flying submarine??
I joke. Now I need to find out what is the correct dial for this.

You might consider reposting this in the Pocketwatch and Vintage forum of this site if you can't solve the mystery.

Whatever it is, it is very cool, IMHO. Certainly looks like a WWII vintage timeframe, more or less.
