 I crank them until you cannot turn the crown anymore. That is when they are fully wound. When I was a kid, I was told that I would break a watch by over-winding it. I read some time ago that the only way of breaking a 649x would be forcing the crown with a plyer. 

A 6497/8 "-1" should have around 46 hours of reserve. A "-2" would have 53-56 (the other mechanical difference being 18,000 v/s 21,600 vph).

The Seagulls will be in line with the power reserve, with the 21,600 vph homage lasting over 55 hours (that has been my experience at least)
