Hey all. I haven't posted in a while. I have just been enjoying the 2 watches I bought this summer & haven't had time online!! Next watch I get close to buying (please be a IWC) I am sure I will be back on again loads!
Rolex Submariner Date COSC is running +7.5 secs per day (which is outside of COSC tolerance -4 to +6)
The sub requires 650 rotations per day (either CW or CCW).
My Rapport watchwinder (travel edition, leather bound, glass porthole) rotates 1690 rotations first day, then 1130 each day after (half CW, then half CCW).
The winder is rotating the watch around twice the number it needs.
The extra winding is causing the watch to run fast.
Is my hypothesis correct or should I take my watch in for an autopsy (it is only 2 months old)?
P.S The winder is not keeping my 7750 wound up as it only winds in one direction!
