I’m surprised how magical watch strap pins really are, I think they’re related to 10mm sockets 😉 Spent the last two days trying to fix or should I say ‘FIND’ the spring pin on my vintage Seiko strap after it went ‘sproing‘ and disappeared, ended up giving up and taking a pin from another vintage watch to fix it. I feel naked without it, only take the damn thing off when I go to bed or have a shower. It was the father-in-law’s and it was left to me when he passed in 2004 – still the have the original receipt from the jewellers from 1978, it’s one of my prized possessions so yeh fixed it but also ended up buying a shed load of pins and replacement watch batteries to fix other watches I have – hey ho never throw stuff away 🙂
