Hello entusiast,

I have an Omega Trench watch I would like you to help me identify. Im quite an amatuer so doesn't know all that much. Here is a short discription:

Omega trench watch in silver casing, around 33mm, with black dial and luminescent cathedral hands. Inside the case there is a stamp which looks like a omega sign inside a key above a 'W'. There are also a stamp with the letters SA in a diamond square.

The movement number is 4.781.xxx and the case number is 5.488.xxx.

Hope you can help me find the production year, model and where it was sold - and if it's genuine

It seems very similar to this posting:

Thanks alot for your help!

Well you're right, it is the same swing ring line as in the thread you found here. It's a beautiful watch and I see nothing wrong here.
I made a thread on mine here : https://omegaforums.net/threads/i-new-trench-in-my-collection.35675/

 

Yours looks original and a little younger than mine, say circa 1915 from your serial number.

Great find, black dial Omega Trench watches are few.

Of course, my movement is finished to finer degree.

 

Those are beautiful watches! - I really like the old trenches. Do you know what the stamps mean? - as fare as I can tell the SA marking is a London import tag, and the middle stamp is French assembly.

and the french mark:

Does that seem likely?

 

Congratulations on a very nice example and for doing some good detective work.
All I can add is that the oval symbol is the Import Mark for the London Assay Office and
the letter "U" is the date stamp for 1915, and of course the .925 mark for Sterling Silver.

So you have a very nice silver cased French Production Omega trench watch imported into London by Dimier Brothers in 1915.

I wonder if it ever went to war? If only these watches could tell their story.

 

Thank you Jimin, that is really brilliant information. Seems the watch has been in a lot of countries. Made in Switzerland, assembled in France, imported to London - I bought it in Spain, and now it's in Denmark. And that is only the information I know of. Still has a blind spot of a 101 years.
I wouldn't know if it's been to war sadly. Is there any records from the Dimier Brothers of buyers? - I suppose if it had been an issued watch, there would be other stamps right? The back has some marks that indicate inscriptions, but they have mostly been polished away. There is still one stamp in the casing, we haven't figured out though. The stamp with the letters and numbers. looks like DENPNSE - AF9876. Any ideas?

 

I will not start collecting another watch type

Do it Jim

 

The word is Déposé (registered, referring to a patent, the number is probably the patent number)

 

Thanks Tire! I just examined the stamp closer and it says. DEPOSE - No9846, which as you say is a number for a trademark or design pattern.

Check out this page, which explaines this particular pattern, and it's importance to wristswatches.
http://www.vintagewatchstraps.com/blog9846.php

The page suggests it is the design of the lugs on watch, and how the are made to hold a single piece strap. This obviously being in a time where wristwatch design was in it's craddle. I would say there is far more advanced features on the watch then the lugs though

It is coincedently also the Dimier Brothers that holds the patent, as well as being importers. Does anyone know if they have a record of buyers, or is that an impossibility to find out? I have really gotten into this amateur detective stuff

 

Hi, thanks for the link, very interesting!

 

On a slightly different note. Do you guys have any recommendations on how often you should have the watch serviced, and how to keep it in the daily life, in order to protect it best?

 

It depends on how much you wear it, your climate and your lifestyle.
I would get it serviced every four or five years, don't get it wet and don't subject it to shocks (like dropping it). Keep it in a benign environment (not too hot, not too cold, not too humid, but just right).
Treat it the way you would treat your grandmother.
