Have a look at eBay, these are quite a common style of watch, they usual have a plated case and lower end pallet pin movement,
I had a similar watch that I gave away on here years ago. I would guess £120 at a push. Don’t be taken in by the link to Breitling which is often spouted by sellers. Sicura bought the bankrupt stock and name when they went bust.
If you like it go for it but if it goes wrong or does not work correctly it will not be economically viable to repair.
