This is my first post to the forum. I have collected vintage watches for over 20 years. I'm reasonably knowledgeable but I've had the watch in these images for around 10 years and I've never really known anything about it. It has no visible maker's name either to the case or the dial. It has a 9 carat gold, double-hinged case, including a central 'block' also made of gold. When I had it serviced soon after I first bought it, my watch-maker said it had a particularly fine movement.
The interesting thing about the watch is that it has London hallmarks for 1916 – 1917. That means it is very early indeed for a square watch and indeed, it pre-dates the Cartier 'Tank' watch, which was not introduced until 1918. The styling of the dial with its hand-painted "exploding" numerals seems equally ahead of its time. As you can see, the watch has a serial number inside the case-back.
Does anyone out there recognise the movement or know who the watch might have been made by?
