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 1950, a popular waterproof model from Omega called the Seamaster.
It has a thick bezel and a dial with small Arabic indexes.
The movement used is the half-rotor automatic movement "Cal342", the predecessor of the fully automatic movement.
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!
