210-220 (this is after 20h of running perfectly fine).

the amplitude would be fine as long as you're in the right position the image you showed way up above look like it was dial down that is not the right position

This was in a vertical position. Like in the short gif video. Amplitude is fine across all positions, at full wind and after 24h. I could post tons of pictures, but please take my word for it.

my friend may return it to the seller if I can't fix it.

this is a interesting remark? In other words your friend is buying a defective watch and hoping you will fix it? So why exactly is the watch being sold in what condition is it being advertised in? One of the problems with Rolex and other high-end watches is people often times past their problems on to unsuspecting buyers. There is a series a Rolex watches where the base caliber  runs at one frequency but the others run at different frequencies and often times we get these watches with awed timing stuff because someone did a mixing and matching of components to make a watch and then pass it off as it has a minor issue. So where is buying this should get some sort a guarantee that the watch is actually an perfect running condition which it's not if you're looking at it as somebody may be just passing problems on to the next person which is why you're having a problem

It was advertised as running fine and my friend was surprised that it didn't. The seller has a very good reputation on Chrono24, so I doubt that it's an intentional pass-on of problems. He responded quickly offering to take it back (and paying for all shipping) or reimburse 300Eur for a local service.

If the problem is what I/we think it is, then the latter is a good offer for ~1h of work and a 50-100 Eur spare part. 

 

 

UPDATE: so finally, it stops every 12h. Always somewhere between 3 and 3.30. Not a precise time. 

Shaking it a bit, will get it running again.

Given that it's repeatable every 12 hours I'd look at the hour wheel or hour hand. It could be a bent or dirty tooth on the wheel, or the hand is touching the date window enough to stop it. Until you get it open, you can't be sure.

Thanks a lot everyone! 

I'll update you as soon as a final decision has been made by my friend (and depending on her decision, what I may find inside).

I have a minor confusion here? The choices were send it back and get all your money back or get some money and have it fixed? Then the wording of the original title was we do diagnostics by crystal ball of not opening the watch up but now you're going to open up the watch to investigate?

No no, your initial understanding is correct. 

I've advised my friend on the situation: possibly an easy fix, maybe a bigger issue. 

IF she decides to keep it and take the partial reimbursement THEN I'll open it and let you all know.

Hello! 

An update! So my friend got 350 EUR from the seller and gave it to me for a look (if I can fix, we'll share the spoils). 

And well, look at that picture. You see it?

Two worn teeth in the SE position?

Is that the hour wheel?

Yes and yes 🙂

Quite astonishing that this damage would stop the watch completely. It's possible, though, that there was some of the debris also stuck.

Not really. That damage came from somewhere and indicates they were in contact with another part. It takes very little resistance to stop a watch.

Hello all,

just to give you a final conclusion to this topic:

I got myself a new hour wheel and changed it without servicing the whole watch. Unfortunately, this problem persisted and I assumed that maybe some debris from the damaged hour wheel continued to cause issues.

So I did a full service.

Now it runs perfectly. Quite impressively actually: average of 0sec/day across 5 positions at full wind AND after 24h -- with a delta of only 4seconds).

Thanks everyone for helping me pinpoint the problem. My friend is very happy now.

      Omega sweep second pinion friction spring - correct tension IS important

      By TimeWerks · Posted

      Thanks for this post MikePilk, I just came across a similar problem with an Omega 1022.  The problem I had was the seconds pinion spring was bent out of shape and did not even engage with the wheel properly, so the seconds hand was not moving at all. (no power loss though :) I removed the automatic module so I could access the spring and work on it. Once I bent it back close to the right shape, I experienced the same problem you reported about power loss.  Many tweaks later, and the seconds hand is moving properly again, with amplitude back to good numbers again. Cheers

      After cleaning up the pivots, I made bushes on the lathe. At this point I've pressed in 6 bushes (3 sets) and the wheels turn smooth. What I can also tell you, is that I'm not looking forward to final assembly. Getting the pivots aligned seems to get exponentially more difficult with each wheel that is added.

      Greetings from Whidbey Island.

      Islands are interesting places to live depending upon their size and other factors. This is a bigger island and it has a bridge to get there at least on one end. It's also big enough that you don't have to go someplace else to get things typically. It can be a problem if you get a job in Seattle though. Yes I've known of people who commuted from the island to Seattle for a job and I don't quite remember how many hours it took but it took a long time. So basically islands are nice if you don't have to leave very often.

      What's your thoughts on this Rolex Sea-Dweller, ref. 16600, calibre 3135 project?

      Thanks @JohnR725! Everything you say makes a lot of sense and is encouraging to read.

      isn't it nice to have a decent case open or when the case doesn't want to be opened? In the case of a Rolex watch that supposed to pass specific water resistant testing you probably do need to tighten the back down. But they shouldn't be tightened so much that they risk stripping the threads out. Then the other problem that comes up is the gaskets can start to disintegrate and then getting the back off can be quite a challenge unless you have a really good tool and perhaps some penetrating oil to loosen things up. Yes really nice case marking. When I was in school we were taught to mark the cases and  the American watch and clockmakers Institute even had a? So if you joined at one time they would give you an identification number. They were explaining or giving an example of if the watches ever found in you have a unique number they can perhaps figure out the history of the watch or identify the body it's attached to for instance not that that probably comes up that often. So you got a unique number and even made a special metal stamp that you can purchase. It wasn't a super big aggressive stamp but still it left a mark in the back of the case. Then I heard from people at work on Rolex watches they were using a felt pen indelible but later on they decided that was bad because apparently the ink could release  chemicals although it seems like once it's dry that shouldn't be an issue. Then of course today was nice is you can keep computer records sealed have to mark anything at all I personally find it's best to leave no reference behind that you were even there. Especially when you have a beautiful watch that has no markings at all and now it has your scribbling all over it not good typically if there is a typical and watch repair?  a lot of minor repairs you don't need to do a complete servicing. But beyond a certain point you're going to have to take apart a lot of stuff you're going to disrupt the lubrication even if it looks perfect right now and yes you might as well just go ahead the service the whole thing. also in a watch like this where a lot of things seem to be going on the complete service would be better then you'll know exactly where you stand versus dealing with unknown mysteries for prior repair.
