Sub Date, running slow again!

Gentlemen,
My 2009 Sub Date was sent to Dallas RSC to be re-regulated, and when I got it back, it was -3 seconds a day. I was happy. Then I did not wear it much since. But started wearing it again daily. I have a desk job, no vibrations, or harsh conditions. I set it to the official US time, and made sure it was wound fully every day, by manually winding it, since I don't move my arms much at my desk. I also tried different ways to place it during sleep, on it's side, and face up. It is now consistantly 12 to 15 seconds slow. I have not abused it, and cannot understand what is causing it to lose so much time. My 5 year old GMT is consistantly 1 second slow, which is fantastic. What is wrong with my Sub??
I am sending it back to Dallas, but is there any advice for me to tell them??

Thanks ahead of time for your help,
David

My advice is to be persistent. I believe that RSC customer service is at least equal to Sears - Customer Satisfaction Guaranteed. I had a similar problem with my Sub. It was running inconsistently after service at an independent watchmaker. A local watchmaker put it on their timing machine and immediately noticed some deviation that is not supposed to be there. He suggested that I return the watch since it had a 2-year service warranty. He even suggested that I mention the hairspring. I did, and this time, it came back running very consistently. The watchmaker even included a timing slip.

I have had similar issues with my year old 14060m. It has never really been very accurate. (by accurate I mean COSC spec) It is now back with Rolex for the 3rd time in a year. I'm not happy with this after paying so much for a watch but there is not much you can do.

It was a hairspring and not a mainspring two totally different components.

As far as I know they have only regulated it in the past and I'm assuming thats what they will do again as the watch is only 1 year old.. I have not spoken to rolex this time around (Leaving it to my AD) as I have not really gotten any information from them when I have called them the past twice it has been in their care. All they say is that they are rectifying the problem.

I hope I have a similar outcome, but this will be the third re-calibration in one year from Dallas RSC, while my 6 year old GMT II chugs away at -1 second per 24h. I wear both watches identically. 15 seconds slow a day is crazy.

What is the difference between a hairspring and a mainspring? I know what a mainspring looks like, but have not heard of a hairspring, or what it does.

The hairspring is what is on the balance wheel causing the balance to return after impulse from the pallet fork. Rik
