Noticed my GMTII 3185 and EII 3186 lose seconds when on the winder, where they are held upright as in a display case, but when I wear them for a few days & leave overnight laying flat, they gain the seconds back. This is normal self-regulation caused by position of the watch?

Interesting.

I guess there is always that exception to the rule when it comes to using winders.

All mechanical watches are effected by temperatures, plus gravity,thats why they are tested at COSC in 5 different temperatures and positions.

FWIW my LV and SD both gain on the winder, while the 3185 GMT and ExplorerII both lose when mounted. Maybe different movements have different reactions to positions?

Face-up position should be best for slightly gaining a little time.

With my 3186

placement / variation per 24 hrs :

side ( crown up or down ) / 1-2 sec gain

flat ( face up ) / 2-3 sec gain

45 degrees / 0 sec gain

upright ( crown to right ) / 1-2 sec LOSS

with my GMTIIc for 22 days result is +18 seconds..but last night it stopped losing or gaining time..yesterday it was +18 seconds and today the same +18 seconds...hope it will start losing time and I hope I won't need to adjust the watch with pulling the crown and hope resting crown up position will help to regulate and hope it will lose that 18 seconds day by day:)

Typically a watch will gain a bit when worn.. This is because the movement of the arm/wrist will affect the amplitude (amount of rotation of the balance) by stopping it before it has fully rfeached the maximum oscillation..

Shorter oscillation (amplitude) quicker tick-tock..

It doesn not matter what movement you have inside...

My Subdate does the same thing.
