SUB LV slower?

[Caps4444]

I had my LV regulated for the 3rd time 4 months ago and it was almost perfect, gaining 0.5s a day......I was well chuffed.....went to a musical last Saturday.....ended up clapping a lot to the music....and have noticed that mu sub is losing 2s a day........that's really annoying......is this a common trait? I appreciate that it is still within specs, but it should not do this!

Well first cannot understand why you had your watch regulated 3 times in a few months.No mechanical watch any brand any price is going to be 100% spot on.There will always be slight daily deviations as long as its within the COSC standard -4+6 seconds a day don't think anyone could ask more from any mechanical watch.You could try resting your watch flat dial up might gain
a few seconds overnight.But remember this 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.

Now even 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.The fact is that no mechanical watch made will keep perfect time, very close yes but perfect no.So whats in a couple of seconds a day in a watch that will last you a lifetime.

....how will loosing 0,5-2 sec/day affect your everyday life.....it a automatic watch...not a quartz.....Just enjoy a beautiful watch

I think you're expecting waaaaay to much from your mechanical movement. There are many variables that can affect the timing, so you must learn to embrace it for what it is and use a quartz watch if accuracy to the second is critical.

mine too !!! It was + 2 secs the first month of life during nov/dec 08 and is now -2 secs....does it bothers me ? Yes...a lot...+2 secs was perfect.

I had it regulated 3 times, as when I purchased it, it was 8 seconds fast a day, after that regulation it became 2 seconds slow a day......I prefer a watch to be fast....so the 3rd time was perfect, for the last 4 months it has been 0.5 seconds fast a day......so I clapped in musical and it's obviously moved something and now it's 2 seconds slow.......my question was not whether or not to get it regulated, that I'm going to do as Rolex is down the road......the question was is it normal for a Rolex to become less accurate by things such as clapping!

[Davvan]

it´s normal.

How do you measure that it´s 0,5 sec off a day? Do you measure this with a compuer or a digital chrono watch? I´m just curious how this is done.

Hello Caps, I can't imagine clapping doing any harm to your movement. If it could, all our watches would be broken. I do lots of outdoor activities with a Rolex on my wrist that definitely subjects my movements to much more bumping around than a simple clap. Just watch it if you are concerned, but I'm sure it's fine. You are aware that simple positioning of your watch, crown down, crown up, can make a watch go a few seconds fast or slow, completely normal. I have watches that are a few seconds fast or a few seconds slow, I just rest them at night in a position that makes them slow down or speed up, in the morning they are close to normal. Throughout the day they will either speed up or slow down, so I do the same the next night. The joys or mechanical watches, you have to love it, don't let it bother you. If you need more info on positioning, look at you booklets that came with the watch.

My Expy II (Polar) runs a little fast...love it.

Never had it run slow....I would hate that.

Just my simple thoughts.

It is a diving watch, clapping should have zero effect. It is still well within COSC specs-working as expected. No automatic will run perfectly without gaining or losing a second or two.

From what padi56 said a few seconds slow or fast is normal for mechanical movements and it's the nature of the beast. I would wear and enjoy your beautiful watch the way it is. Of course the alternative is to buy a watch you can set to the atomic time(which is done daily) or continue to love your masterpiece, the Rolex!!!

Just by clapping hands most certainly doubt it,myself have used and very abused one of my SDs while working as a dive guide around middle and far east.Never missed a beat but not very anal about time as long as in a reasonable few seconds that will do me.But I remember coming back home to the UK a few years back from a very hot humid climate.My SD started to loose about 15 seconds a day,but rectified itself when returned to the warner climate.And when they regulate a watch on the timing machine,it don't necessarily mean it will perform the same on your wrist.What will be accurate on one wrist might be a few seconds either way on anothers wrist its because its mechanical.Your watch is fine and there is no need to get the back off for regulation, try resting watch flat with dial up at night.
