Antique Swiss CORGEMONT pocket watch, Art Deco, silver side open face, in good working order

We would like to introduce you to an antique pocket watch from Swiss CORGEMONT.

This is a Swiss pocket watch from the CORGEMONT WATCH brand, believed to be from around the 1920s.
It has a slim silver case with Art Deco-style decorations all over it.
Due to a dent on the side, the crystal bezel does not close properly and has been reinforced with glue, but this does not affect use.
The dial has the word "CHRONOMETER" written on it, but it is unclear whether the watch itself is a chronometer-compliant movement.
It is unknown if it has been overhauled, but the balance wheel is in good condition and ticks along smoothly.

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