Aargh!

[Gedanken]

Not that I'm getting anal retentive about accuracy, but this is ridiculous.

Just a few weeks ago, I had my SD regulated at the Singapore RSC, and the technician said that it was running at +1 second per day when he was done (it was at +10 when he got his hands on it).

This afternoon I checked my watch against www.time.gov and it was 30 seconds slow, so I synced it again. four hours later it seems to have lost about three quarters of a second, and it's looking to go past the -4 COSC spec.

This is getting to be irritating, especially since it was just regulated and seemed to run fine for ten days. Does anybody have any ideas why it's behaving this way and what I can do about it? the only thing I can think of is the move from Singapore to Melbourne, but since it's summer there's not much of a temperature difference, and in any case, it's gone from being fast to being slow. It's about 18 months old and should be a long way away from its first service, so I'm just wondering why it's suddenly behaving so erratically.

Since a normal day has 86,400 seconds, even a watch that runs five minutes fast, or slow each day has an accuracy of over 99.6 percent!. A Rolex mechanical watch that gains or loses about nine seconds a day or about a minute a week has a breathtaking precision of over 99.99 per cent. This is very high precision, given the fact that the movement is constantly affected by the earth's gravity, metal expansion and contraction, temperature variations, subtle changes in lubrication and friction, shocks, and so on.All I can tell you James,is I had my watch regulated in
the RSC Singapore. While there,and in Bali for over 3 months.my SD
was + 2 sec a day,but when I returned to the UK,yes there was temp difference,but not a lot.But a huge drop in humidity,my watch went from + 2 to - 13 secs a day.Just see how it goes for
a few weeks,if not happy get it looked at and regulated again.

Have to sympathise and agree with you on this one, James. Knowing how anal I am about accuracy, I would never accept the kind of deviation you are getting from your SD at present.

COSC means COSC and it bloody well has to be within the specs of a COSC rated watch - no ifs or buts on that!!

I will NEVER even accept anything more than +2 secs./24 hours from any of my watches. My Rollies are virtually spot on and I'm so happy to say, so is my new Crosswind - perfect timing is what I always demand from a high-end Chronometer. They are designed to give you mind-blowing accuracy and I've never been disappointed with them.

Have it regulated at your nearest AD, but this time ask him to keep it for a couple of days and monitor the damn thing himself. Trust me, that'll work better than merely having it done in half an hour and then bringing the watch back home. Give the watchmaker sufficient time to monitor the watch.

Good luck - JJ

Thanks for putting it into perspective, Peter - I needed that.

Yeah, JJ, I'm thinking this may be one of those weird transient things. I'll give it a few weeks and see how things shake out.

Have you been , eh, enjoying yourself with you watch on lately

Now, if I remember a lesson from Dave Knoll, the watch would actually run faster as it reached the end of its power reserve.

In all seriousness, your memory serves you right. Since I've been wearing the Breitling so much, I noticed the other day that the TT YM was running quite fast...like at least 2 seconds over normal. Then half an hour later it had stopped!! So I guess it's true about a watch gaining time during its dying moments!!

JJ, you killed the YM? OMG!!! Are you going to cremate it or give it a burial at sea?

Before you do that, send it to me. I have a new process I invented for restoring the life to dead Rolexes. It's a secret process still under development so I can't divulge how it works. But if you send the dead YM to me immediately, I may be able to rejuvenate it.
