Thanks Lani to answer so quickly,
Ok that's really a big problem for only one watch,for the ROLEX GMT II ERAMIC.
For the ROLEX GMT II PEPSI that's ok the date change at 00 h 10 so only 10 min.
I just checked there is few minutes that's maybe because of the GMT HAND the date is maybe sync with this hand.
i explain :
When the GMT HAND arrive at 00 h 00 anything past but wen it 00 h 10 the GMT HAND advance a little bit and at this moment the date change.
So maybe that's the problem don't you think.
I really don't want to send the watch back to king.
to many risk with the custom.
wating for your news.
Friendly Philippe.
