Circa 1908 Antique Longines Pocket Watch, Open Face, Diameter 55mm, In Good Working Condition

We would like to introduce an antique pocket watch from Longines, a long-established manufacturer with a rich history dating back to 1832.
[Brand Introduction] Longines

This is a large-sized alloy case pocket watch from around 1908.
At 55mm in diameter, it is larger than a standard pocket watch, and with its clear indices, it is believed to have been a professional timepiece used by organizations such as the railways or the Ministry of Communications.
While the overhaul history is unknown, the balance wheel swings well and it keeps ticking energetically.

We hope this "once-in-a-lifetime encounter" becomes a special one for you!
