Omega De Ville Tresor from the 1940s - Vintage Discussion

luk_h · Aug 12, 2026

Hi all,

so i recently found a imo beautiful vintage omega de ville at a dealer in town. The dealer itself sells several vintage and modern watches and jewerlery. The watch comes as it is with 1 year warranty. They claim that the movement works good the age, However, the dealer doesn't strike me as a vintage Omega specialist, so I'd really appreciate your input. Winding it was very smooth, movement started after a few turns, and setting also works smooth.

I haven't been able to find another example with the same case and dial combination during my research. Can you tell me if the combination of case and dial is authentic? I already asked for photos of the inner caseback and movement. Will post them as soon as I get them. Is it a "de ville tresor" from the 40s? Do you might know the reference number?

I'd appreciate your thoughts.

Thanks!

This watch has 'Cornes de vache' lugs and, if solid gold, looks to be a locally cased watch (no Swiss hallmarks on the back of the lugs)

Silver hands with a gold watch means they have been replaced, even though they seem to be of the correct type (leaf hands).

Dial is of a 1940’s style and could be original Omega, but it is not clear if the case is Omega. Dial also has some environmental damage.

Unless you are sure the case is 18K solid gold, you absolutely love it as it is and are buying at the gold melt value, I’d tell you to find another watch.

It's a charming watch, but hard to say if the dial/case combination is authentic with the information and photos provided. It is not a DeVille Tresor, and in fact the DeVille line was not introduced until much later, I believe the 1960s. If you got that information from an AI model, I'd caution you that AI is notoriously terrible at identifying and authenticating vintage watches.

Edit: As a minor side-note, in general, I like to gather all of my information together before making a thread, because people often will view a thread only once and then move on.

They claim its a solid 18k gold case, how many grams of gold would you estimate the case contains? 36mm case

The only way to know if it is solid gold is to see the hallmarks inside the case (even then it might not be conclusive )

Unless English or French, locally cased watches are often in lighter cases.

There is absolutely no way of telling how heavy the case is from pictures.
The lugs may be hollow (very likely) and the case back may be very thin.
Plus there could be a base metal spacer around the movt.
