Antique ROSSKOPF pocket watch, circa 1900, 55mm diameter, railway watch, functional.

We would like to introduce a pocket watch from the Swiss watchmaker, ROSSKOPF.

This is a large pocket watch, believed to be from around 1900.
The back cover features an engraving of a locomotive, suggesting that this watch was used in the railroad industry.
The crown is tight, and the power reserve is relatively short.
While the overhaul history is unknown, the pendulum swings well and the clock is ticking vigorously.

I hope this "once-in-a-lifetime" encounter will lead to a special meeting for you!
