Well I guess the better way to find out is to ask.
IWC Slevin , inner bezel, pusher at 4'00.
What is the correct way to operate it for turning the inner bezel ???
1) Push and turn anti-clockwise ??
2) Turn anti-clockwise without pushing ???
...and last question: in order to start / stop the turning of the inner bezel with the pusher at 4'00 ..... the pusher does it have (or should have) a kind of a lock / unlock (sort of screw down or up) mechanism which you need to engage before..... or you just turn the pusher and that's it. ????
Thanks for the help guys.
BTW , Dealer is PT (Precious) watch is really great and PT did an excellent job.
