I really enjoyed reading this thread, thanks.
Just thought I would share my Services watch with you. It has a lot of sentimental value to me. It was my granddads watch back in the 70's. We found it when clearing the loft after my gran passed away. It must have been up there for 30 years or so, obviously not working and with a cracked crystal and worn smooth crown. I bagged it and had it sent off to Steve Burrage who did his usual magic and got it working again (keeps good time too, gains a few minutes a day).
