Circa 1911 Antique Longines Pocket Watch Silver Side Hunter Case Roman Index Good Working Condition

We will be introducing antique pocket watches from Longines, a long-established manufacturer founded in 1832.
[Brand Introduction] Longines

This is a silver-sided hunter case pocket watch from around 1911.
The front and back are engraved with intricate floral patterns in the Art Nouveau style.
I think this type of watch was made to order as each one has a different engraving.
The dial and mechanism are in good condition.
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!
