The Vintage Wrist Watch Company has dated this piece to the 1920s.
The watch has a nicely jewelled Swiss stem-winding movement , calibre 998, which is working well. The movement is protected by an inner hinged cover.
Cyma was founded by two brothers, Joseph and Theodore Schwob, in 1862.
The Cyma name was officially registered in 1903. Sandoz used the most modern of manufacturing processes and produced very high quality time-pieces, trademarked as Tavannes, Cyma and Cyma Tavannes. Their excellent reputation for quality meant that by 1910, Tavannes / Cyma were one of the largest Swiss watch manufacturers in existence.

The watch measures 51mm diameter excluding the winding crown and the loop. The case is gold plated and is the Star model made by the Dennison Watch Case Company. It is in nice condition with just light surface marking from use.

The winding crown pushes in to release the front cover. Inside the glass lens is in nice condition.
The dial has a small nibble to the outer edge at 3 o,clock but otherwise it is in nice condition and it has blued steel hands, a subsidiary seconds dial and an outer minute track.
The watch will be sent in a new presentation box.
