The Vintage Wrist Watch Company has dated this piece to the 1930s.
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.
This particular watch measures 50mm diameter excluding the winding stem and the loop. The case is the gold plated Star model by the English watch case maker Aaron Dennison. The case is in beautiful condition, nice crisp engine turned detail to the front and back.

The winding crown pushes in to open the front cover.
Inside, there is a glass lens which is in lovely condition (some reflection showing on the photo).
The dial is signed ‘To The Admiralty, James Walker, London’. James Walker was the original retailer of the watch.
The watch comes with a 12ct rolled gold double chain. Each length of chain measures 20cm long including the T-bar and the clasp.
The watch and chain come in the James Walker presentation box.
