What a watch, what an incredibly beautiful perpetual calendar watch, in steel, at an unbelievable price point for a movement of this quality. The L.U.C 96.51-L powers this 43mm watch. Again familiar territory for Chopard, in a tried and true way - microrotor movement, twin barrels, 27 jewels. This was the first time this watch has been on my wrist. It will happen again, I have no doubt, hopefully as my own.
