Not really a Rolex-question, but...

Maybe out of order, but here it goes;

As a Rolex user, I'm also fond of other brands both cheap and more expensive. A GMT-watch that I really enjoy with an ETA movement shows the following behaviour;

Tuseday morning 7.00 am - fully wound (60 turns) and set.
Tue 17.00 - Took it of
Wed 03.50 - Put it on
Wed 19.00 - Took it off
Thur 07.00 - Put it on
Thur 17.00 - Took it off

Didn't wear it Friday, Friday at 21.00 - the watch stopped.

I did a test with the watch fully wound and not moving it = 47h (about)

Does this sound normal to you? This suggest that the wearing tue-thu didn't manage to wound it fully. Since I'm a pilot I don't move around a lot, but still I'm active between flights.

My Rolex seems to hold up it's power reserve much better. I really don't know what ETA movement it is, but again it does have an GMT-hand.

Thanks a lot and again sorry for the off topic question...

Wearing habits and movement is the only thing that keeps a watch wound. Just wearing it doesn't.

I would be pretty sure that your watch stopped simply because it eventually wound down to only the movement your daily activity put in it, as they all will, and the 28 hrs it lasted is pretty normal for most wearers.

Thanks, and yes - I guess so too. But still - it seems that my Rolex holds up a lot longer. After wearing that one like described above I can get 2 days out of it...

I would not surprise me if the Rolex has a more efficient auto winding system, but 47 hours is pretty good power reserve.
