Circa 1900 Antique Lagrange Pocket Watch 800 Silver Case Open Face Works Well

Introducing the LAGRANGE pocket watch.

This is a pocket watch with an 800 silver case, believed to be from around 1900.
The "LAGRANGE" on the dial is of unknown details, but it appears to be Swiss-made.
The 800 silver case features a relief decoration of an airplane.
There is some peeling on the dial, but otherwise it is in good preserved condition.
The overhaul history is unknown, but the balance wheel swings well and it ticks energetically.

We hope this "once-in-a-lifetime encounter" will be your special meeting!
