Update: IWC Vintage Series Aquatimer, ref 3231-01

It's been 2 weeks since I got the watch and it's keeping perfect time.  I've been observing the accuracy, and if I wear the watch all day (16 hours) and leave it crown up during the night (8 hours) it looses about 1 second a day.  Then I tried leaving it crown down during the night, and bingo, it doesn't gain or loose any time.  Well, at least nothing I can measure in daily basis.  I will do a long term test starting tomorrow to see how much it will gain/loose in 2+ weeks.

Overall, pretty impressive time piece.  Technically speaking, it's better than a quartz watch.
