Can anyone advise me how I can get this watch fixed? I am in the UK. i bought it in 1990 in Oman. On the face it says "West End Watch Co. Sowan prima". On the back "West End Watch Co. Everbright. S-3721 4555" It's a mechanical watch, which you have to wind. As it is, after you wind it, the hands start to move, but after a few minutes it stops. I tried to get it fixed a few years ago & the man said he couldn't find a part it needed (something to do with the winding stem). https://photos.app.goo.gl/B6D2AvjeCHDv3bi97 https://photos.app.goo.gl/jS6gTWTDaTGR22ASA Many thanks.
