1919 British antique John Finlayson pocket watch with silver Denison case, in good working order

We would like to introduce a pocket watch from the British company John Finlayson.

This is a sterling silver open-face pocket watch from around 1919.
The dial has "John Finlayson" written on it, but I couldn't find any further details.
The movement is Swiss made, but the sterling silver case is made by Denison Case, a high-end British case manufacturer.
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!
