Aide identification (débutant) - Vieille Omega

Bonjour.

Les modèles de cette époque n'avaient pas de nom ou de référence à proprement parler, tels que les modèles ultérieurs.

26.5 désigne la taille du calibre du mouvement, utilisé par Omega dans les années 1930–1940.

Il y a plusieurs de ces mouvements avec des évolutions graduelles.

Thank you for your reply. How much is it worth, given that the dial appears worn? And would it be worth restoring it or replacing the glass?
I would like to keep it and wear it occasionally. It's my first automatic watch 😁

A service is always recommended for wearing the watch, but it comes at a cost. Around 300-500€ at a good independent watchmaker certified by Omega. The watchmaker disassembles the movement, cleans it, oils it, reassembles it, etc. They clean the case (ideally without polishing it) to remove grime, change the crystal if it's damaged, etc. It's better to avoid touching the dial. It's a delicate piece that doesn't lend itself to cleaning.

If the watch has sentimental value, it's perhaps worth considering. The movement is particularly dirty and the parts can rub against each other. This can lead to more complicated problems to fix later on, even if the watch isn't used regularly.

I'm not an expert on these models, so perhaps someone else can comment on an estimate and on the originality of the dial, which matters a lot. The size of the watch also factors into the equation.
