danielv2000 Posted February 10, 2016 Report Share Posted February 10, 2016 So I took my v72 Daytona out of the safety deposit box today and put it on my wrist until I got back into the car. On my way to the office, I looked down and noticed the hands had started moving. Is this normal? I've never had this happen. This is a manual wind movement. Is it possible there was some power reserve left ? Thank you all! Quote Link to comment Share on other sites More sharing options...
Revere Posted February 10, 2016 Report Share Posted February 10, 2016 It is possible the watch had just enough wind left for the balance to swing when the movement is initiated by wrist movement. Static friction is always more than kinetic friction, so if the mainspring could not exert enough torque to get the balance going, it is still possible for the torque to keep the balance going once movement is initiated.
