We would like to introduce you to watches from OMEGA, a Swiss watch manufacturer founded in 1848.

This is a self-winding mechanical wristwatch from around 1958, Omega's popular waterproof model, the Seamaster.
It has an elegant design like a dress watch with a silver dial and gold bar indexes.
The movement used is the Cal. 503, a 500 series automatic movement with calendar.
It comes with a beautiful emerald green leather strap.
The overhaul history is unknown, but the accuracy is good and the automatic winding mechanism is problem-free.

We hope this once-in-a-lifetime encounter will be a special one for you!
