Really? I believe you, but I would have have thought just the opposite. So they run faster just before they stop running?

Enjoyed this post very much. Thanks.

Interesting, but much simpler....Get a timegrapher and find these results with great ease

I've heard watches actually run a hair slower fully wound, and faster with a low power reserve left, then again I've also heard fully wound watches run faster, but the somewhat technical explanation I read for a full wind causing the watch to run a hair slower made more sense, even if it's counterintuitive. Something about more mainspring power making the thingy :) swing further and stronger, which increases the time it takes to rebound, thereby slowing the next increment of time a tiny bit.

Excellent. Why the coins?

As the main spring unwinds more,it has less torque on the drive-train, so the movement would run slightly faster due to the slight change in the amplitude.Now when wearing a watch with the main spring at full torque in most cases it will run constant beat rate, than if a watch is not worn.This is down mainly to the effect of gravity and your wrist movements having affects on the overall amplitude of the hairspring.This is why on a watch-winder a watch could be slightly different in its accuracy than when its on the wrist.

Very interesting, thanks for the input.

Can you deduce anything about the YM that went from 5 seconds fast to 10 seconds slow in the few hours before the power reserve ran out?

Why, to prove that all the watches are authentic, of course!

Thanks!

Almost felt like I was reading a narative to a horse or car race.

Nice collection you have there. Thanks for sharing.

Great post and thanks for the effort taken. Nothing wrong at all with a little bit of OCD, live with it daily

Watch Professor · 13 July 2011, 12:10 AM

Great post. You gave me confidence that my OC condition of keeping track of accuracy is not that serious.

Each morning I check the accuracy of my 2 Rolexes and Speedy Pro and keep a running tab on the computer. I've found that my GMT IIC has averaged -0.75sec./24 hrs., my Sub Date +1.25sec./24hrs., and Speedy +2sec./24hrs.

What is quite intersting is that changing positions hardly affects the Rolexes, but does have an impact on the Speedy. Strangely, the dial up position slows it down while the crown up position speeds it up.

Thanks for posting.

Great test thank you very much!

Sixxgrand1 · 13 July 2011, 01:48 AM

Thank you sincerely for taking the 'time' to complete and post your results.

Question: Is your Explorer II running the 3186 or 3185?

TSW · 13 July 2011, 01:58 AM

Cool experiment!

Thanks for the comments! I've got a bit of a follow-up, but it will be a few weeks before I can post it.
