Advice needed: Rolex stopping suddenly & regulation

[pereiraex]

Hi guys,

I recently got a new SubC (ref: 116610LN) and I've noticed two main issues:

1. The second hand stops suddenly when the power reserve is close to empty (say 36-48 hours after last use) - now one might reasonably think that it's simply the Rolex not having anymore power reserve to continue running, but no: if I give it a very slight shake it starts running again seemingly as per normal.

2. The watch is running 5 seconds slow on the dial up position - should I send it to regulate? I assume this is free as the watch is still under warranty?

Do let me know what you guys think especially with reference to point 1, are your submariners the same way? I'm hoping there is nothing seriously wrong with the internals and I'll probably get it down to the RSC next chance I get, but would like to hear from you first.

1) This is normal. It will stop when the PR runs out and 48 hrs is good.

Giving it a shake with no PR left will activate the escapement and start it up again for a few minutes.


2) What is the rate result when worn by you in a normal wear pattern for a month?

The rate when running dial up, presumably on a table, doesn't really tell me much about it's precision or accuracy in normal long term wearing.

1) I can confirm my sub runs for a few minutes (2mins~) upon shaking when it has almost no PR left, exactly as you said it would. So I take it this is a non-issue then?

2) I haven't actually worn it consistently for a month now. The reason why I'm just a little hesitant on taking it into the RSC is because I've heard stories of watches getting scratched and dinged when being returned from service. Is this still common?

Thanks! great community to be a part of.

For a few seconds off I wouldn't risk having issues.

+1 on the first point, as Eddie says. Newer models like the SubC don't really respond to positioning regulation like the older models/movements. If it's under warranty, yes, Rolex will regulate it free of charge. Just got my Tudor done under warranty.

Yes, it's a non issue. Are you in Singapore? If so, maybe you can check with the local forums there for feedback about RSC issues.

Make sure you wind the watch up 40 full turns of the winding crown. Are you doing this? Simply shaking the watch after the mainspring has unwound is not sufficient to keep it running or maintain any type of accuracy. If you do not wear it on a consistent basis maybe a watch winder would be beneficial as it keeps the mainspring fully wound.

My Sky was running 4.6 seconds slow - averaged over many days with different wear patterns. On the timegrapher the A/D found more inconsistencies between the positions.

I had it checked and regulated at the RSC under warranty and couldn't be happier. Now ~0.5 sec fast. Perfect.

I don't understand the concern of a watch stopping when it's out of power reserve.

Live with it. All mechanical watches gain or lose a bit. Just part of the life. Strictly my opinion.
