The Vintage Wrist Watch Company has dated this piece to the 1920s.
G Thommen (Revue-Thommen) was founded in Waldenburg, Switzerland circa 1853 by Gedeon Thommen.
The watch has a good quality movement, with a snail Cam regulator, and it is working nicely. The movement is protected by an inner hinged cover.
The watch measures 50mm diameter excluding the winding stem and the loop.
The case is in good condition with attractive detail to the case back, and a vacant cartouche to the centre.

The watch glass has light marking but is very acceptable.
The white enamel dial is in good condition and the Breguet style hands are a handsome feature. The SUF on the dial, with an image of a cog at each end, probably relates to the factory, eg, Schweizer Uhrenfabrik which translates as Swiss watch factory.

The watch comes on a silver single chain which measures 25cm long including the T-bar and the clasp. Each component and link has the lion silver mark. The silver fob has an initially shield to the centre with a rose gold wash.
