Circa 1939 Omega pocket watch, K18 yellow gold, thin open face, in good working order

We would like to introduce pocket watches from OMEGA, a Swiss company founded in 1848.

This is a pocket watch made of solid 18k gold around 1939 with a thin open face case.
The back cover has a simple design with no engravings, but the area around the pendant has a distinctive Art Deco style design.
The 18-karat gold case is a typical yellow gold, has almost no scratches, and is in good condition.
The case is Swiss hallmarked for 18k gold, and the dial, case and movement are all OMEGA stamped.
The overhaul history is unknown, but the machine is in good working order and ticks along nicely.

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