I had a brand new Toute a Vitesse edition for five days before I noticed a problem with the timekeeping after the alarm sounded. The hour hand would no longer advance (in fact it would temporarily move backwards a certain amount of time after the alarm) if the alarm was set past :30 on the hour. This just happened a few weeks back and I'm heart broken now having to wait weeks (optimistic estimate) before I'll get it back from Blancpain. My AD has been great to work with so far. Just disappointing after getting the piece I really desired and having spent so much.
