Check your bracelets from time to time...

I just went to take off my ExpII 216570, and the oysterlock clasp would open halfway and stop, and I couldn't take the watch off. On closer look the screw attaching the clasp to the bracelet had backed out and was sticking out far enough that it was blocking the oysterlock from opening fully. I unscrewed it, cleaned it, and reinstalled it with a dab a blue loctite, and checked the other screws. The scary thing is I was on vacation on La Jolla a couple of weeks ago and wore this watch snorkeling, biking, etc, so I'm really glad I didn't lose it!

Check your bracelets!

Good to know, thanks for the advice!

Good catch!
I used clear nail polish a few years ago and it's still good to go (in case other members are in a pinch without loctite).

Thx for heads up! Yeah, a very small bit of Loctite blue applied to the screw threading via the tip of a toothpick works great.

Best is purple loctite. Blue is a bit too strong for small bracelet screws. Never use red (strongest). You'll likely destroy screw head trying to get it out with red.

Also, apply the purple loctite to the threaded hole with a toothpick (versus putting on the screw threads). You don't want the loctite getting all over the inside if the moving parts of the two links when pushing the screw thru.

Similar thing happened to me a few years back. Noticed the safety portion of the clasp was opening and closing with resistance. A screw had worked its way out just enough to rub the mechanism. Did the same thing you did. No issues since.

Good advice. I have a small service kit I use at home to adjust bracelets, etc. Putting the loctite on the link as opposed to the screw itself prevents the loctite getting inside the link itself and causing the link to stick. Avoiding this makes the bracelet more fluid and comfortable.
