Hi Eddie,
Still looking for my fat CWC, but my fat 1982 Precista takes a Rayovac 344.
Hope this helps!
Best Regards,
Adrian
Does anyone know the correct battery for the 1980 CWC "Fat" G10? I phoned CWC today and they don't know. :roll:

Thank you Adrian. I don't know if I should mention this but I have 16 of the "fat" CWC which I will be offering for sale as soon as I take photographs.

Hi again,
As ever, find it as soon as I stop looking :roll:
and my fat CWC from 1983 has a 357.
Cordialement,
Adrian
I tried a 357 Adrian and whilst it works, it seems too thick.

I agree it seems to be a tight fit!
In the interests of experimentation, I've swapped the batteries over.
The 344 is loose in the CWC, almost as though it needs the extra height of the 357 against the caseback lip to locate it properly. From what I can see of the mechanism inside the CWC it doesn't come right up to the edges of the battery space, so a thinner battery tends to rattle around.
Conversly, the 357 goes into the Precista OK, and what you can see of the mechanism comes close to the battery hole, so that it can locate the thinner 344 without major problems.
In conclusion, I'd go for the 357 as it fits both.
Wow, never realised it could be this complex :shock:
Best Regards,
Adrian
Hmmmm, I have a few watches to experiment with so I'll try the 344 & 357.

Eddie,
I'm using a #344 in my 1980 CWC with no problems. The three prong spring in the battery hatch should exert enough pressure on the battery to keep it in place.
Nice find, I like the 'Thick' versions, they have a good feel and weight about them.

Just to throw in further confusion, I've been using a 395 in mine with no problems :wink:
Cheers

It's most confusing! CWC say that the 371 is the correct battery for the "thin" version but don't know which one the "fat" version takes. I've got two here running fine, one with a 344 and the other with a 357 but in another one, when you tighten the battery hatch down on a 357 the watch stops, suggesting that it's exerting too much pressure on the movement..
Thanks all for your replies.

Hi Eddie,
You may have already picked this up, but a chap called Simon Smith on the MWR site has all the answers :D
For British Forces CWC G10 type watches:
Simon Smith, MWR post 07 July 051980: First pattern. No-oval dial. 13mm thick, crystal to caseback. AS/ESA 536.121 movement, no jewels. 386 battery. Battery hatch on centre line.
1982: Second pattern. Logo has oval. Everything else same as first pattern.
1983: Third pattern, variant A. Logo has oval. 11.8mm thick, crystal to caseback. ESA 947.121 movement, seven jewels. 386 battery. Battery hatch offset.
1984, 1985: Third pattern, variant B. Same as variant A except movement is ETA 555.112 (marked Marinium), battery is 394 and battery hatch is on centre line.
1987 on: Fourth pattern. Logo has oval. 10.2mm thick, crystal to caseback. ETA/ESA 955.114 movement (and other equivalents), seven jewels. 395 battery. Battery hatch on centre line.
These features have been observed over the years. Some watches may differ, particularly in regard to movements, if they have been repaired or modified over the years. Also equivalent movements may have been substituted from new.
No wonder it was so confusing!
Best Regards,
Adrian
Thank you Adrian, what's even more confusing is that CWC gave me different answers!

Ah well, perhaps you need to use the system suggested on the lable of RAF Mk3 Coldweather flying jackets-
"Size must be Determined by Selective Fitting" :D
i.e. try them on until you find one that fits!
I handed mine back years ago, but that phrase still lodges in the memory.
Best Regards,
Adrian
Eddie.
There are at least 3 calibres used in these watches
ESA 536 121 correct battery 344 but 343 as a subsitute
ESA 947 111 correct battery 381
The other movement I have at home and cant remember what it is
Hope this helps
Cheers
Ian
Thanks Ian, I now need to buy more batteries. :D
