A thinner design to fit into the 42 mm case. It still retains the bidirectional self-winding chronograph mechanism and its column wheel visible from the dial.

The Pellaton type automatic loading system has been replaced by a double ball inverter. HOWEVER, the power reserve remains unchanged (72 hours).
