24 Days, 5 Seconds.

[f16570]

I normally wear my watch 24/7, however from the first of this month (November) I have not been sleeping with the watch on as I normally would.
As of now the watch has picked up on 5 seconds in 24 Days!
The watch has been placed crown up while I sleep, but other than that is not of my wrist, October the watch gained 1 second a day while I wore it 24/7.
I find this quite simply amazing for a mechanical watch.
Just thought I'd share.

That's amazing timekeeping, Fraser!

Rolex rulez!

Not me Bo, it's the watch that's doing the hard work.
Have you worked out the value of the 20 Rollies you flipped yet?

I still can't help but be amazed at human mechanical ingenuity, I know most watches now have computer designed, laser cut gears etc, but it is the human design factor and the fact watches were being made hundreds of years before computers and automated manufacturing technology were even thought about.
Amazing that mechanical timepieces can be so accurate.

Wonderfull accuracy!

Nah, I daren't think of it!

Anyway, with my economy I have to flip to get something new.

I purchased a Z series Exp II in mid Sept. The first two weeks it was dead on. Over the next month it gained about a .5 seconds per day. So after ten weeks, only off while sleeping, it has gained 20 seconds. It does not seem to matter which orientation I place at night. Pretty amazing so far.

How about 5 sec's in 24 hours. Well, to be more exact my SD is 4.875 secs a day over the last 8 days. It seems to be slowly creeping up much to my chagrin.

Mike,
Have you tried setting your watch in different positions at night? My Tudor chrono will speed up 2 seconds if I wear it while sleeping. Set crown down it stays the same. Set dial up and it will lose about 2 to 3 seconds at night.

I have always worn my watches when I go to bed but I may have to change that if the current trend continues and give this a try.

So do you recommend not wearing the watch to bed as this somehow affects the accuracy? Do you think the watch needs to "rest" for a few hours each day?
Just checked mine it was 12 seconds slow in 26 days

Hi Bill, I could not cope if my watch was slow.
Not sure if it needs to rest, but when I slept with my watch on it was picking up on average 1.5 seconds a day.
If you think that your arm is pointing at the floor for a large part of the day then the oil flows towards the crown, so leaving it crown up overnight allows the lubricant to move back through the watch, possibly causing friction against the movement enough to slow the watch down.
