Time Keeping Accuracy
Hi, it's Rob again. Can I also please ask if someone could advise me on how exact Rolex's time keeping is. I'm losing up to 5 secs a day which I didn't really expect. Is this normal?

Well that depends on how maticulous the watchmaker is with reguglating thw watch. I have got a SS Daytona that was -3 secs/ day and I had it regulated and its now spot on and I mean spot on daily. I had a Exp II for 10 years and that was spot on from first day without any regulation. I also had a TT Datejust that was spot on after a service. Now I have a GMT IIc that is running +4 secs/day I am letting it run in and perhaps I will send it back to get it regulated. Because I have had Rolexes in the past and my present Daytona with superb accuracy, I am spoilt, and I want all my Rolexes to be just accurate.

No mechanical movement any make any price is going to be spot on accurate.There will be always slight daily deviations.The set COSC standard is a average of -4 to +6 over 24 hours.Try resting you watch off wrist at night flat dial up might gain a few seconds.Remeber its mechanical and in 24 hours, the escapement of a mechanical watch pushes the gears 432,000 times. Since a 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 finer mechanical watch that gains or loses about six to 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.Its a simple fact no mechanical watch made will keep 100% perfect time, very close yes but perfect no.

-3 seconds or +4 a day is superb.And if any mechanical watch runs to or inside the COSC spec you should be jumping for joy. Below is the COSC testing standards first colum for movements of Rolex size.

My GMT is losing about 6 seconds over 24 hours. I think I will have to take it back to the AD. What do you all think?

How soon should I take it back? Or should I say how long do I have to let the watch break in and bedded? My Daytona I had it for about a year before I sent it back for regulating.

I would'nt loose sleep over +5 a day. Its well within spec and may change over time - when you get it serviced ask them to regulate it so it runs in tune with your wearing habits. But there's nothing wrong with it.
My Sub ran at +6 (regulated to +3), my DJ at + 1 and my Omega Seamaster runs at +4. I just bought a 2003 GMT which has been sitting in a safe for 6 years doing nothing and it runs at - 0.5 !! There are so many variables so as long as your watch runs within spec it's doing very well - just wear it and enjoy it.

My Sub is 6 months old and is ~+5 secs per day.
When it was new-er (1-2 months old) it was +7 secs per day. It seems to have settled in nicely. |

Cannot understand why your watch is 99.996% accurate I would be jumping for joy with such tremendous consistency and accuracy.And I would seriously doubt if a watch running + 4 seconds,would ever have a detrimental part to play in your life.

I like accuracy, but some people can go overboard, I had an idiot one time tell me he would rather die than have a watch that was off 3 minutes a year. I had to bite my tongue to keep from blasting him.

Maybe after 3-6 months. Although I think the break in idea might not be accurate, and if it is, I would think a new watch would be 'broken in' in a few weeks. Mine was 3 months old when I sent it to Dallas last month.

I don't mind if it gains one day and losses on another as long as the overall result is there about the correct time. I don't like it if it constantly gains or constantly losses. Sure it is not a detrimental effect on my daily life, but if it gains 4 secs a day that means it would be out by 2 minutes every month and I just don't want to adjust it every month. I know it is no big deal but I don't want to know my watch is not telling the correct time, when it can be regulated to more precisely. Its like wearing a fake watch you know it is not the real macoy.

You will not get that level of consistent precision even with the highest grade mechanical watch - that's simply the nature of the beast and you either have to get used to it or go quartz, which is consistently far more accurate over a longer period of time. I know which I would prefer

What can I expect to pay to get a watch that doesn't lose any time at all?

Try leaving the watch dial upwards overnight and see what happens to the accuracy. d. |

Have to agree with you the most important thing with any mechanical watch in consistency.Afraid today Rolex has done a great job over the years brainwashing quite a few that all Rolex mechanical watches are spot on accurate.But in the real world thats not so there will be always tiny daily deviations.And to get any mechanical watch to self regulated,say by different resting positions at night is quite rare in the real world.But in general to loose a few seconds rest watch vertical crown up or down.But for any mechanical watch to show such consistency of +4 seconds I would be very very very happy.Nothing is perfect not even Rolex or any pure mechanical watch for absolute perfect timekeeping its that simple.
