Accuracy effected by activity?

[bycrom]

Question guys, I have had my 116610LN for about a week, it has been spot on and seems to be (barely) a second lost in a day.

However when I got back from Hawaii it was over 2 minutes off? I was in Hawaii for 5 days and I have a super active 8 year old who is go, go, go, go, and go some more.

We swam all day ocean/pool everyday which included jumping in and out of the water, me throwing her into the air (100's of times it seemed), water slide, in hot tub afterwards into cold water... just endless.

For the time difference I had to adjust my watch twice and this required the second hand to be stopped, but I am sure my total adjust time was no where near two minutes.

So my question is can the activity above effect my watches precision? Or am I in some kind of new watch breakin window?

Thanks as always.

A mechanical watch that stays wound will run somewhat slower than a watch that is not getting as much activity.

This may seem counter-intuitive, but someone will be along to describe amplitude and its relationship to timekeeping.

Have you considered the Einstein's theory of special relativity?

Very interesting, I need to read up on that, thanks.

I did long ago in school, I recall being totally fascinated, and blown away.

I agree hectic activity affects accuracy but my opinion only

[FiguredMaple]

I was told by a watchmaker at the local Rolex SC that prolonged periods of constant activity on a daily basis would cause the watch to speed up.

activity, resting angle, temperature, knocks, bumps all play a part.

Off by 2 mins in 5 days...

+120 sec in 5 days / 5 days = +24 sec/1 day

This seems very excessive and I don't see how hyperactivity could explain that much variance. Perhaps you missed something when you changed the time? (It happens.)

In the case it might have been knocked, I would keep it wound and monitor it for the next few days.

I am sure gravitational forces, temperature, how the watch moves,.. all have effect on the accuracy. However 2mn seems a little high.
Is the watch running normal now? If yes, then maybe something else in Hawaii "the mysterious island effect" :)

I have and it hurts my brain muscles.

To the OP: It will equal out even if things do affect it. Time it over a month or more and see what happens. You might be pleasantly surprised.

Security may have magnetized the watch in the airport. Stop by a local watchmaker and have them demagnetize it.

Hey.

I just got back from Hawaii Wednesday. My SDDS runs spot on even with zip lining, scuba and chopper tour etc. Where did you stay?

I will say that there is not enough information here to make any judgements...

We do not know how the watch was first set, and by what standard it was re-set or recalibrated to arrive at the conclusions...

Setting a watch, or resetting one several times over 5 days is folly in attempting to know how it is running.. Especially if it's being checked against a cell phone, computer, or some other source that gets it's own signals up-dated at random intervals...

However, yes.... activity will affect how a watch runs.. Typically vigerous activity will act on the balance (hairspring) and keep it from completing a complete oscillation. This shortened "swing" (amplitude) takes less time to complete and, therefore, the watch will run faster.

Good points, and I have no concrete data for my 2 minute discrepancy, it must have been user error, etc. After returning I set the watch to http://www.time.gov/ and at this time it has only lost about 1 second. I will continue to monitor, I guess to fully quantify this I will need to head back to Maui for five days...

I now believe this is user error, after a week long test this watch is off by less then a second, as noted here.
