How much torque is needed to turn the screw or is it quite slack? The screw head is weird as it's not slotted all the way across and the sides look radiused under magnification so looks like there is quite a risk of the screwdriver blade slipping

Thanks so much again

Very little, but they tend to be slightly "sticky" so gently does it. Given the shape of that screw I would definitely grind a notch so you get a good clean purchase. Worth to spend a little time on, you've got it for future use then.

In my experience I've often been told to not use Vaseline on o rings as it's petroleum based. This can degrade some rubbers quicker than silicon based lubricants. YMMV.

I recently attempted to regulate my 10 year old C5 with the ETA 2824. I wasn’t successful, it still loses about a minute a day. I think it just plain needs a full service.

But good for you getting into tinkering! It’s fun. Don’t be afraid to make mistakes though, it’ll likely happen along the way.

You’ve been given some great advice here that I will add my support to :D :thumbup:

My local Rolex AD will do a full suite of pressure tests (vacuum, compression and condensation) for around $60 on any water resistant watch. They can test 600m no problem. Depending on the time of year there may be a backlog so it can take a little time but worth it if you use the watches for purpose.

Ooops! I meant to say far cheaper if you do more than a few water resistance tests. Sorry about the confusion.

My local Rolex AD charges $150 for any watch to be water tested. I used to take my quartz Tag Heuer there for battery changes and water testing until I started tinkering and doing this on my own. But I live in an area where the cost of living is ridiculous.

Thanks rkovars for clearing this up. Again, my apologies.
Best regards,
John

I've had some screws that were tighter than others, so I think it does vary. I pushed down on one movement that was really sticky, and saw that the hairspring/balance wheel seemed to pause before resuming. All ended well, but definitely take care not too push down too hard on the screw in establishing leverage to turn it.

My guess is you've already tested for magnetization Alex, but just in case? Losing a minute a day sounds like the movement might be magnetized.

I have not checked that! I just assumed a 10 year old movement needed a good stripping and re-lubing. I could try the demag route first though, thanks for the tip.

You bet! For heavily magnetized movements, it can often take several passes with the damag device in my experience before it is resolved.

Oooffff! $150 is steep and would add up quick! As an aside, that $60 includes a battery on quartz watches. They are a top notch shop.
