Hi,
Just wondering if any of the members can please help me out on finding the movement maker for this 32-33mm trench watch. Non precious metal case.
Cheers Russell.

I don't believe it's Omega/Patria/Tissot etc.
Can we see the inner caseback?

I'm guessing American(nickel cased? A-R+ F-S), calling @OMTOM , @Tire-comedon, @JimInOz

Wish I knew how to google that engraving on the back......unit symbol, I bet.

There is only a serial number on the inside of the caseback. It is a military issued watch hence the caseback marking. I sort of thought Tissot or Eterna?? Maybe Lanco.
Cheers Russell.

The engraving on the caseback is similar to artillery symbols I've seen.
You may want to bring this to MWR's forum for help.

British pheon (broad arrow) surmounting the letter I, possibly indicating an Indian service watch.

Or possibly not, it may remain one of life's smaller mysteries.

Yes it is British military to India I'm guessing. The movement diameter is around 27.5-28.0 mm using my ruler.
Cheers Russell.

Close but no cigar.
These are German WWII, by the way.
Those are unit type markings for maps. More specifically just the artillery symbols. When you draw locations of units on maps you use those or pieces of paper with those symbols to denote unit type. US and British use almost identical markings.

there are markings for every conceivable unit type out there.

Looks an awful lot like this movement sold by Dimier Bros, which David Boettcher speculates was made by Fontainemelon or Schild: https://www.vintagewatchstraps.com/movements.php#dfc

His whole site is worth a browse for a look at many movements from this era. Nice piece!
Hi,
Yes I often reference David's site which is fantastic. I have checked the movements and the one you link but still not the same.
Many thanks.
Russell.

👍

No longer a small mystery.

However, the toe at the foot of the barrel bridge is proving a problem.
I can find may calibers from different ebauche makers of similar design, but so far none with the tell-tale toe.

Of course I completely missed it when looking through Ziggy's book.
Cheers.

Any movement maker with that picture?

That's your picture. I just took the colour down and cropped it. Makes it easier when going through books to compare.

Haha....Didn't give it a thought. The movement has a serial number on it so it could well be associated with a watch company rather than a standard ebauche movement? What do you think JiminOz?
Cheers.

Many watch companies purchased ebauches in various states of completion/finish and them made them their own.

Then again, there were many companies (mostly all defunct now) from the first half of the 20th century that made movements very similar to yours, i.e. the train bridge shape, balance cock style etc.

One good thing is that your movement has an unusual round hairspring stud and that "toe" on the base of the barrel bridge, so good identifiers.

Another way to help identify is to check the shapes of the setting parts under the dial, there may also be makers marks under the dial.
