Patek Philippe

Housed in one case are two fully independent movements. Each complete with its own mainspring, gears, and balances. Movement 1 in addition to time, also includes the repeating and split seconds chronograph work. Movement 2 is time only. 

Winding and Setting of both Movements:  

Winding 

Both movements are wound independently through the winding pinion on the stem, which apart from the regulation index for movement 2, is the only point of mechanical connection for the two movements. Winding is actioned by turning the crown clockwise which will wind one of the movements, the other movement is wound by turning the crown counterclockwise, once both movements are fully wound the crown is effectively locked.  

Hand-setting 

Movement 1-the blued steel hour and minute hands are set by pulling the crown up and turning the stem, seconds are indicated by the dial at the right. 

Movement 2-the gold hands are set by depressing the olivette at 1 o’clock and turning the stem, seconds are indicated by the dial at the left.
