Hi guys, you can help me?
I have found this watch by my grandmothers cave. I don't know whats this for a model and worth it?

 

Your grandmother lives in a cave?

Regarding the watch, it's an early 1970s Heuer Carrera 1553s with the Buren Caliber 15 movement.

Value is very dependent on condition. Yours looks to be in reasonable condition aside from the dents on the side, probably needing a service, but will look much better after a crystal polish/replacement. The rest of the watch should not be touched or polished - cleaned only. And a movement service. I'd probably put the value at about £2000.

 

Sorry, sure not a cave. I mean a Screed.

Thank you for your first feedbacks.

What you think about the service by Tag Heuer. Is it a good option or better by an another watch maker?

Is there a correct bracelet to buy anywhere? Did anyone know them?
