Seamaster 2531.80 Questions - Diver's Extension and Servicing

Hello,

This is my first post on the forum and I am very excited to be joining. I was recently passed-down a Bond Seamaster from early 2000s, reference number 2531.80. Overall, the watch is in excellent condition, but I’ve noticed that the diver’s extension is extremely loose to the point it comes undone half the time I’m taking the watch off. I’ve noticed that the diver’s extension does also sometimes “unclick” while being worn on wrist with everything fully done up (although I can “click” it back in with a bit of pressure. After doing some searching on the forum, I’ve seen a few other users post similar issues. My question is whether the diver’s extension being so loose can negatively affect any other aspect of the clasp (like wearing/rubbing against other parts of the clasp)? It’s just a small annoyance that doesn’t really bother me, but if I should have it fixed to prevent any other damage I definitely will do so – the closest AD is just fairly far away and would rather avoid shipping if it’s not something I should be worried about.


My second question relates to servicing and how well the watch should be keeping time. Right now, the watch seems to lose aprx 5-6 seconds a day, and I was told that it was serviced 4ish years ago. I’m perfectly content with this accuracy, but again just wanted to know whether I should be servicing it right away and/or expecting better timekeeping.


Thank you in advance for your help/suggestions/insight, I look forward to learning from everyone here.


Z.E.

Regarding clasp, here's very good explanation form @Archer how diver's extension works and what can be done.

I'd check if tabs aren't worn and if not then just pry open two forks a bit.

Also check if you are closing it correctly.



Accuracy - if you have watchmaker nearby, ask to check watch on timegrapher. If amplitude is above 260 degrees and positional variance is not bad then just wear the watch. -5 seconds per day is pretty close to COSC. If you can't stand it then ask to regulate to more acceptable rate. I'd service only if amplitude is low or there are severe rate differences between positions.

Thank you so much for the help and information! I'm honestly just a little leery of prying/messing with the forks on the clasp as I don't want to screw things up even more (I'm quite bad at working with my hands, have ruined a number of things trying to 'fix' them haha). I actually haven't been paying attention to whether I'm closing it correctly, and that VERY well could be the issue! There is a local watchmaker that specializes in Rolex and Omega who has really outstanding reviews:

I might take the watch to him to examine the clasp and tell me what he thinks! I guess my only concern is that the loose extension would be putting pressure or anything on any other part of the band/clasp if it were to "unclick" while being worn, as I honestly don't mind it opening up when taking it off.

Also huge thanks for info re: accuracy- I'm quite new to the world of automatic watches and will have to look up some of these terms (amplitude/positional variance, etc.) just to get a better understanding of how it all works. I honestly don't even truly know the difference between regulation and servicing, so will look more into that! Do you have any resources you would suggest for someone new to this like me? I'm sure Squires Watches would be able to test things with his timegrapher - the accuracy doesn't bother me at all I just don't want the watch to be wearing/grinding itself down (which I understand can happen if not serviced/lubricated/oiled properly?).

Thank you so much and apologies for any stupid questions. This seems like a wonderful community I am excited to join. Obligatory wrist shot:



EDIT:

Was definitely not closing the diver's extension properly, which has solved the issue of it "clicking" open while the bracelet is closed. It still is a bit loose when taking the watch off, but nothing I can't deal with. Thank you so much for the help!
