Montblanc

one of the most interesting part of that particular watch is the patented crown locking mechanism

 

(US patent # 7404669B2). 


It allows the owner to have two fold control function with the crown in the same axial position making it possible, for instance, to control a timezone function when the crown is rotated in the first direction, and a date setting function when the crown is rotated in the opposite direction.  Inadvertant rotation away from the desired directed is "blocked" by the control lever. 

Thanks for sharing that interesting find...I've only seen one a few years ago at the MB boutique in Las Vegas

Best, Mike
