Vintage cocktail watch??

If the watch is important to you or yours, have a watchmaker look at it and assess it for condition and quote you a price. Then decide whether you want to spend the money. We can’t help you with that decision. As to a bracelet? It likely had a black nylon cord strap with a deployant buckle on it. It looks art deco to me, so possibly late 1920s or thereabouts. It has potential.

Your watchmaker may have a strap to pair it with, but they are easily available elsewhere. Just a quick google search for cocktail watch strap will bring up a bunch of options

Looks to be in nice shape. Certainly worth a service.

This type of cord bracelet awas likely the type that was used on the subject watch when new. These cord bracelets were (and may still be) available with larger diameter cords which would be best suited to watch cases with larger diameter holes in the case lugs.

There’s an old adage that goes something like this: Any item might be said to be worth more to the owner than it is to anyone else. What an item is”worth” will depend on the individual.

If you or your family member don’t ascribe sentimental value to the Omega, then it is likely not worth what it will cost you to have it serviced. This is as much a family artifact as it is a watch. You might be able to buy a “toss away” watch for very little money. Deal directly with a watchmaker who has a good reputation among antique and vintage watch enthusiasts, and ask for an estimate for the repair. Once you know the repair cost, you can decide for yourself whether it is worthy of you spending what it will take. What it is worth to you is more important than what it might be worth to others. If you need a referral for someone to service the Omega, tell us where you live (we don't need your address!)
