·I have a PO2500 42mm with a bracelet in a great shape (minimal stretch), but the diving clasp opens almost every time I get the bracelet off. Is there a good way to tighten up just the dive clasp opening?
Any way to tighten the dive clasp on a PO2500?

·Mine does, too. It started after a few years in.
It’s a bit of a nuisance having to fold it back in every time, but I just live with it. The little nub that catches the extension might have worn down, not sure. I haven’t taken the needle nose pliers to any part of the bracelet yet - maybe something could be tweaked to tighten it up. Or you could mention it to your AD or watchmaker and let them do it, which is probably the safer option.
My trusty 2010 orange bezel (now nicely faded) PO 2500 resides on a black Uncle Seiko GL831 strap most of the time, anyway. It’s like a whole different watch - looks great, perfectly balanced, and comfortable for days on end.

··Omega Qualified WatchmakerIf you look at the typical dive extension from that era, it is sort of a tuning fork shape, and over time the "open" end on the left gets compressed, and ends up narrower than it was originally:
So the first thing I do on these is to use a wedge like a large flat head screwdriver, and sliding it in the gap to expand it slightly. This can tighten up the extension, but unless you take the extension off the rest of the bracelet so you can open it up a lot, it usually doesn't fully tighten the extension.
So the next step is to look at these small tabs:
I use a staking set for this, but you could do it on a sturdy surface with a small punch:
I use the staking set punch to slightly expand the tabs, which increases the tightness of the extension:
Just go slowly with this - it doesn't take much...
