WTF Brain Trust - As I mentioned the other day, I got my Pro Diver back from Invicta Service. The piece which has a Selita SW200 was no longer winding. I had it running within a second per day before it broke down.

Now it's running minutes slow each day. I've heard that you need to let the oils settle in if it's new or newly cleaned, which I assume they did, but I would expect it off by seconds not minutes. Is this normal?

I think I reset the time around 1:00 PM today and just seven hours later it's already close to two minutes slow. I've already cracked the sucker open and ajusted the timing screw which was one tic below the midpoint to one tick above the midpoint, i.e. set to the line that's between the midpoint and the + sign. Now I figure doing that will speed it up by seconds not minutes. Can the screw be move beyond the plus sign or a complete turn or two to speed up the movement, or is there some serious problem with the timing of this piece?

So what should I do? Let it settle in a bit for a couple weeks or so? Send it back to Invicta since they did not fix it properly? Rotate the timing screw a turn or two if that is even possible? Bring it to some local jewler who might be familiar with the Selita movement? Help!!!!!!!!!!!!!!

Thanks in advance to any sound advise. :crying:

Hi Time Bandit. Your movement is capable of COSC specs. Rather than drive yourself nuts with adjustments, take it to a watchmaker who can accomplish the task in minutes rather than days.
A Selita movement is essentially an ETA 2824 (very common) with an extra jewel to help increase power reserve

I'd check to see if it got magnetized somewhere along the lines during shipment. This can cause erratic running and I'm hard pressed to believe they wouldn't check accuracy to make sure it isn't that far off. I've heard that each discernible movement of the regulator can be as much as 15 seconds a day, so giving it a big budge may provide what you need.

How does one go about demagetizing it? I'm assuming that my best course of action will be as Bosco suggested, a jeweler who's familiar with the ETA movement. Do most concur with that?

Unless you're willing to roll the dice and possibly be the cause of even more costly repairs, I'd say take it to a watchmaker.

One last question - Thanks by the way for all the prior answers.

Post Deleted. Apparently not relevant.
Sounds like my safest, and best bet to that matter, is to have a jeweler adjust it since it might have been magnetized among other problems.

I noticed that the prior post suggesting to nudge on the regulator was removed. Can I assume that one should not try to move that one way or the other by applying some force to that arm as suggested on the pic? I had never heard of that and been only advised to move the regulator screw, or whatever it's called, towards the + or - sign depending if it is running fast or slow by a few seconds. Based on most of the feedback, it sounds like I should find a jeweler who knows what they are doing fix it.

Thanks for all the advice guys. This site is invaluable for the novice watch collector.
