The Vintage Wrist Watch Company has dated this piece to the 1920s.
The watch has a seven jewel stem-winding movement which is working nicely.
Williamsons supplied various companies with movements, and they also founded the Buren factories in Switzerland in 1898.

The company fell foul of the law when they claimed their watches were English Warranted. It transpired that the movement components were actually being manufactured at the Buren factory in Switzerland and then exported to England. Consequently, the English branch was expanded in order to comply with the Law.

H Williamsons was subsequently bought by Smiths Clocks and Watches.
The watch measures 49mm diameter excluding the winding stem and the loop. The case is silver and there are hallmarks inside both of the cases backs for Birmingham 1926 with a maker’s mark for the case manufacturer Dennisons of Birmingham. Overall, the case is in good condition, just one 5mm indentation to the edge of the case back.

The dial is in good condition, and it has its original blued steel hands, a subsidiary seconds dial and an outer minute track.
The watch comes with a later silver double albert, with each chain measuring 21cm long including the T-bar and the clasp.
The watch and chain come in a new presentation box.
