Hi all. I just purchased a new IWC Portofino and love it. I have a number of other watches that i also wear and rotate them. So here is my question. When i am not wearing my Portofino I put it into my watch winder. I noticed that the watch will ultimately stop and that the watch winder really doesn't impact the winding. Not sure why? I have two other Rolex's in the watch winder and they seem to keep perfet time and not lose complete power like the IWC.
