The Vintage Wrist Watch Company has dated this piece to the 1920s.
The movement has been identified as a Marvin.

The watch is a good size at 31.5mm wide excluding the winding crown and 31.5mm high excluding the fixed wire lugs. The case is silver and there are hallmarks inside the case back for Glasgow (import mark) with a date letter for 1926 and an importer's mark of JW for James Weir of Argyle Street and Buchanan Street, Glasgow. The case has the odd minor mark and some gentle unevenness to the back but overall is in good condition for a 1920s piece.

The lens is in good condition.
The signed dial has a very faint hairline running up from the centre but it is not visible to the naked eye. Blued steel hands, a subsidiary seconds dial and an outer minute track.
A new leather strap has been fitted.
The watch will be sent in a new presentation box.
