Well that's why i wanted a BNIB watch and not one from the window display. I suppose that the break in period is the same but the it's bad when the watch is not working

That is fantastic accuracy.

The four second thing could be nothing more than the watch starting and everything settling in.

Frostie,

I have had my watch on everyday since I first put it on my wrist 28 Dec 07. It was +1.5 within the first 2 weeks. Last weekend I was +3 and last night I was still +3. I too take mine off while sleeping crown up. I will check it again in two weeks and let you know.

Thanks a lot. I 'll make a new thread in 20 days where i am going to talk about the accuracy again and my observations

JostheBoss · 1 February 2008, 06:26 PM

Velitsko, I noticed the same phenomenon when I set my watch. I checked it over about 7 days before sending it in to RSC for that crown issue (it's back btw! they said there was nothing wrong, probably thought me typical of a new owner!).

I noticed ny watch lost 2.5sec within 24 h, then ran 3.5-4sec slow by 48h! I was distraught! I thought that at this rate I'd be resetting my watch every week to fortnight :( But I knew it was still within COSC so I didn't pay much mind.

After 7 days, I checked it again. It was now running 1sec slow ONLY?! Somehow it had caught up :) But I do sleep with it as well, so maybe the crown's all over the polace during the night, averaging out to "catch up!"

I'll do a more controlled test when I get it back today. RSC snobs sent it back in a brown envelope wrapped in tissue paper!! Pssh, as if! At least they polished it :)

Later

will you test all six directions/orientations
dial up
dial down
crown up
crown down
crown left
crown right
the result is useful to me

116710LN · 1 February 2008, 07:46 PM

I found that if crown up, my green hand loose 2 sec per day, if crown up, it loose 1 sec per day!! Dial up gained 1 sec per day.
it should be six orientations, perhaps we should test all
dial up
dial down
crown up (12 o'clock)
crown down (6 o'clock)
crown left (9 o'clock)
crown right (3 o'clock)

jimroe · 1 February 2008, 10:15 PM

Velitsko, your experiences closely track my own with my GMT IIc. When I first got the watch, it ran consistently slow - initially about 4 seconds a day but settled down to 3.5 seconds a day. Two weeks ago I was in LA and I stopped by the Beverly Hills RSC to have it regulated. After the girl at the front counter balked (It's perfect - it's a mechanical watch) she took it back to the watchmakers who timed it and found it -3.5 in one position and -2 in another so they regulated it.

I set it 5 seconds fast exactly two weeks ago. The first day I wore it all night, and it lost one second that day. The second day I also wore it all night, and it lost another second. Ever since then I remove it at night and leave it dial up, and today it is the same 3 seconds fast that it was 12 days ago.

Needless to say I am now very happy with how it's regulated AND the consistency of the watch - two different things I might add. A watch can be consistent but not well regulated - as mine was before the visit to BHRSC - or it might be well regulated and "average" the right rate, but be subject to large gains or losses that cancel each other out depending on position.

Glad that you received your watch back. You are probably going to be really happy right now

You watch has good accuracy you don't have to worry about anything

Sorry Bro, is that so important to know accurancy of our watch?

No but i am just curious to see if it is within specs. I was never into accuracy and all this stuff.

SPACE-DWELLER · 1 February 2008, 11:20 PM

You have a VERY precise watch, Velitsko! Congrats!

My SS GMT IIc was regulated in those six positions just recently at my AD. Now it keeps perfect time. It is absolutely bang on!

Sure. It is a timepiece after all. I don't obsess over mine, but it's fun to check it when you first get it and make sure it's within COSC standards.

frostie · 2 February 2008, 01:39 AM

Here's another one

newrolexman · 2 February 2008, 02:44 AM

I got my new GMT ll c on saturday 1/26 and its been -3 seconds each day which bugs me.

I will keep tracking it. I dont mind paying the extra bucks for Rolex but I d like an accurate watch.

If in a few months I keep losing 3 seconds a day I will have it regulated.

frostie · 2 February 2008, 02:49 AM

Actually i prefer more a watch that is running fast to watch that is running slow

nice pictures, especially the second one, under the sunshine

Gil F. · 5 February 2008, 04:57 AM

That's great timekeeping accuracy! I think that watch position has a lot to do with how much time your watch gaines or loses. Since getting my SD back from the RSC, I have gained a total of 2 seconds over the past (almost) 5 days. I have noticed that taking my watch off at night and putting it crown down keeps it from gaining much time.

JBat · 5 February 2008, 07:12 AM

A guy on another forum was talking about the precision inherent to the GMT IIc. He said that while some copies of the watch are better regulated than others, he had yet to hear of a piece that was outside of COSC standards out of the box. I don't know how accurate this is, but it seems to gibe with what I've read here and elsewhere.

He also mentioned that this particular watch seems less affected by different positions, and this has been my experience as well. My watch has been a very consistent 1.5 seconds slow in the 6 weeks I've had it, and I've worn it every day. No matter what position I leave it in at night, it's a rock solid 1.5 seconds slow a day.

This is good news. Precision is the hard part with mechanical movements, accuracy is fixable. The GMT IIc is very precise, and seems to respond well to the simple regulation that then allows it to be very accurate.

mborkow · 5 February 2008, 08:16 AM

my watch was initially a little bit slower, but is now at -4 a day, every day, no matter the position. i assume that i could have it sped up just a touch and then it would keep near perfect time...but i'd have to part with the watch for a week or so.

frostie · 5 February 2008, 08:21 AM

14 days so far and the watch gained only 1.5 seconds. I just checked my watch. The 4 second issue is over and i also agree with what JBat said that this watch seems to be less affected in different positions

JBat · 5 February 2008, 08:30 AM

That's phenomenal accuracy, Velitsko. I think it works out to around 36 seconds a year, and that's great by anyone's standards.

I know that it's phenomenal accuracy and i am quite surprised. I think that i am going to leave the watch crown down this night.

I am glad that the 4 second issue is over. It seems that the watch starts to break in and get's used to my wearing habits

robbyrolex · 5 February 2008, 08:35 AM

My one month old sub date seems to gain 2 seconds a day regardless of wearing habits. One minute a month fast works for me.
