Losing exactly 1 hour...?

[Uhtred59]

My Explorer II is in the shop for losing time. Fortunately it is within the warranty period. My issue is when the watch gets cold, even on my wrist. After an hour in below freezing weather it begins to loss time in batches.

Mine began to fail this way before it no longer jumped. When you set the time is the spring nice and crisp?

I think there's something to Brad's point. If it's losing exactly one hour, I'd be suspicious that it's somehow related to the 12 hour hand jump hour module malfunctioning.

Whatever the issue is, it is time for Icehockeyboy to send it in for service.

'Nuff said.

Only on the date change.

And no effect on anything at all if you're going by what is supposed to be "home time" (24hr hand, which isn't connected to that spring).

The 24 hour hand is "reference time" and (for many) is set to GMT since GMT doesn't change between standard time and daylight saving time. The 12 hour hand (for many) is set for the local time zone where you are and can be "jumped" without hacking the movement when changing local time zones as you travel as well as when changing between ST and DST. The 12 hour hand changes the date at midnight.

Wait, what?
Don't we need to discuss this here further?
Another four pages should suffice before it is sent to the RSC.

Then check daily with same time source over 5 days, then average out daily timekeeping if then it really is losing like you say. Then you have a problem that has to be looked at by RSC.

Good point.

I have in a hurry set my watch to 11:20 when it was 11:25 while leaving the house. I didn’t have any appointments that day that were down to the minute. So it went unnoticed it until the next morning when I panic that it lost time. Then set to the second on time .gov and it’s fine the rest of the week.

I know this is an old thread but just chipping in to say my Explorer II also lost exactly an hour last night.

It lost 2 hours about 3 weeks ago but not sure if that was all in one go or not. - I had recently got off a plane from a different time zone so assumed I had set it incorrectly on my return - then it did it again this morning.

But even more stangely the red hand was also 1 hour late! - so it was in sync with itself but still almost (around 55 mins) exactly I hour out.

Its probably 7 - 8 years since new so time for a service I think
