First post here. I found this watch in a drawer after my grandmother passed a few years ago. The case was scratched, the movement was stuck and there was no strap.
I took it to the amazing watch repairer at Piccadilly Circus tube station and he got it running for me.
I would love to know more about the watch as I'm a huge fan of all things mechanical (currently have a triumph spitfire, a 3 door range rover classic and an early renault 5).
My dad says that the initials on the back are those of my great-grandfather and EFCO was the company he built up and then sold (in 1955?).
The movement is 12.68Z and 17 jewels. The hallmarks confirm that it is from London, was made in 1954 and is 9ct gold. I don't know what the Baume 304 means though. Any ideas?
It's a really noisy movement, is this normal? I get a lot of complaints from my girlfriend about it. Also, how far should I wind it up? Thanks!
