The Vintage Wrist Watch Company has dated this piece to the 1930s.
J W Benson Ltd was the official watchmaker to the Admiralty and the War Department and also held a number of royal warrants, being watchmakers to Queen Victoria, the Prince of Wales, the Tsar of Russia and several other royal families.

This particular watch has a Cyma stem-winding movement, calibre 939. After the first World War, Cyma became one of Benson's main suppliers of movements. This movement is working nicely, with a good strong tick, and the time keeping is good. The movement is signed J W Benson, 15 jewels, Swiss made and it is protected by an inner hinged dust cover.

The watch measures 50 mm diameter excluding the winding stem and the loop. The case is silver and there are hallmarks inside both of the case backs for London 1935, together with the the monarchs heads of King George V and Queen Mary to celebrate their silver jubilee. The case is also stamped with the maker’s mark of JWB for J W Benson. The case has some small marks and a couple of small “dings” to the back but overall is in good order for a 1930s piece.

The plastic lens is a later replacement it is in good condition.
The white enamel dial is signed J.W.Benson, London. The dial has an old repair at 4 o'clock and faint hairline cracks although not over noticeable.
The watch has its original blued steel hands.
Price includes worldwide postage.
