will running with your watch effect the accuracy?

[Andad]

I'll have two bob on Larry.

A Forum member once demontrated that shaking a watch quickly and violently from side to side had a serious affect on the balance wheel and lowered the amplitude. The watch would run slightly faster and pick up a few seconds. He would use this method for his watches that were running slow.
A search might find it.
This method was not recommended.

No offence, but the explanation given makes no sense.

I do not run very fast..

[cdnwatchguy]

running negatively affected the accuracy of my right knee so it might affect a watch too.

Your watch uses a balance (the hairspring is wrapped around it) that typically rotates (oscillates) about 300 degrees. This is the regulator of the tick-tock, and ideally it oscillates (ticks) 28,800 times per hour. When it does, your watch is absolutely accurate to the n'th degree...

When you vigorously swing your arms (wrist), then the external force you are applying affects the balance and it does not make it to the 300 degrees before it is forced back......... and your rotation (amplitude) is then only about 240 degrees as an example...

It takes less time for the balance to rotate 240 degrees than the full 300 degrees and so as long as that external influence exists, your watch then "ticks" at 30,000 beats per hour... it speeds up..

Therefore, in theory, a watch that is worn will always beat slightly faster than one on the dresser (or a winder) because of the external forces... and vigorous external forces, such as the treadmill or jogging, will have much more affect than simply walking..

You're welcome.......

This is correct and makes perfect sense!

i think yes. especially if your watch is not used to that motion. if you always move around with your rolex (ex daily wear) then running will have much of an impact and the opposite also goes

[Paracentesis]

LOL. The concept of a watch "getting used to" your daily activities is a lovely one. Back in the real world: lots of people all around the world run with their watches, and I'm sure Rolex and other watch manufacturers know this. If there was a significant effect on timekeeping (which there isn't, IME) then they would put a little disclaimer in their literature.

Rolex accuracy is an oxymoron. Rolex makes jewelry.

If you want an accurate watch, buy something like this.

[Paracentesis]

Quite, but completely beside the point. What we are discussing is whether vigorous exercise will cause a Rolex to gain 30 seconds in 24 hours. Extremely unlikely, IMO.
