I have an Omega Dynamic Geneve from the 70s. The watch sits in a circular hole on the bracelet and screws in with a ring on the back, but the clasp is broken. It’s says 1153/138 on the bracelet.
I tried buying a custom leather strap so I could wear it but the leather stretches unattractively over the edges of the fastening so I think I need to deal with the original braclet. I’ve been monitoring eBay for years at this point but the replacements are outrageously expensive.
Any advice for what to do with a sensible budget? Perhaps I’m looking in the wrong place?
I’d just look into getting a third party modern bracelet that matches the style as best as possible. Somewhere like Strap Code or Uncle Seiko might have what you’d want.
