can airport security magnetise a watch
Hi,
Does anyone have an idea if airport security systems can magnetise a watch? I've been flying to Stockholm and back for a few weeks now and last week I noticed that my watch was gaining and it looks to be 90 seconds in a week. I went to an AD today and it gains 8 seconds, but there is nothing wrong. They did demagnitise it, the salesrep said. The flying is the only change in my schedule for the last weeks, so I tend to look there for a cause. |

Had all my watches through the scanner many times and never noticed a problem with gain or loss of seconds. I may be wrong though.. better get a Milgauss.

I don't travel as much as some round here, but I've never had a problem.

I swear it happened to a Seiko Sumo of mine on a trip to the DR. Ran extremely fast after that.

Well lately somehow my exp II gains 9 seconds a day. It used to be around 4 seconds day.
I've I travelled amsterdam - stockholm every week for the last 8 weeks so that triggered me sinde it is the only change in schedule I've had. |

If any watch is magnetised in general they will speed up and run very very erratic and in most cases not by just a few seconds or they can stop and refuse to start.If your watch gains a consistent 9 seconds a day then the fact its consistent I would doubt if its magnetised in any way.Many things could effect a small difference in overall accuracy just a simple change in temperature state of power-reserve in mainspring. Remember this the escapement of a mechanical watch in 24 hours 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. This is still 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.

No is the short and simple answer. The frequency used, and the low power level of the electronic field wouldn't affect a watch.

@:PADI56 - Normally I'm not so fussy about the accuracy, but the watch ran "true". And the engineering feat is as you describe is incredible.
@77T - Then I'll leave it and try and regulate it back down at night. |

I don't think that I would single out the half a second that you spend walking through a metal detector as the culprit though.

According to Einstein, the further your watch is above the earth the slower it runs, right, due to weaker gravity

There is a very simple way you can check this for yourself. Buy a $1 compass on eBay. Lay the compass on a flat surface and wait until the needle settles. Move your watch slowly toward the compass and see if the needle moves. If it moves, there is magnetism.

Could it have been the food on the plane?

Had a very similar experience. My 14060M has been no more than 1-2 secs fast a day for months. After a trip to London recently it started to be more like 10 sec a day fast. Haven't done anything about it yet as everybody writes that magnetism in airports shouldn't be an issue. But wonder what else it could be?
