If you’ve ever spent 20 minutes fiddling with a watch band, trying to seat the spring pin before throwing it against the wall, then check out this little watch-band spring tool. It belongs to that class of tool that’s pretty useless 99% of the time — and totally worth the few bucks you paid for it 1% of the time.
The tool’s pointed end can remove pins from wrist bands, so you can make size changes and repairs. The flat, forked end can slip between the watch body and the wrist band, to get at the spring bar that keeps the two connected — it’s perfect for gently prying it out or resetting the pin. If you’re careful, you can remove your watch’s back with the flat end, without damaging the watch’s cover.
You can get a cheap one for just a couple bucks — a jeweler-quality version will run closer to $30.
