The Vintage Wrist Watch Company has dated this piece to the 1920s.
The movement is stamped with the word 'depose' (short form of Modèle Déposé) which is Swiss/French for "Registered Design". The movement is protected by an inner hinged cover.

The watch measures 50mm diameter excluding the winding crown and the loop. The case is nickel and is stamped 'solid nickel' inside the case back. The case has marks and some scratches commensurate with its age. The watch glass has minors marks but is very acceptable for a 1920s piece.

The enamel dial has a couple of very faint hairline cracks and a couple of fairly inconsequential marks. Charming Breguet style hands (pin set), subsidiary seconds dial and an outer minute track.
The watch comes with an albert which measures 27cm long including the T-bar and the clasp.
