Perrelet Turbine Skeleton A3038/1

Perrelet's trademark is a rotor on both the dial side and the back of the movement, and the Turbine turns the dial-side one into a propeller modelled on a jet engine. On the Skeleton, which Perrelet showed in 2015, the turbine is weighted at the bottom and spins as the wrist moves, with the hands and hour markers set above the blades. Behind it runs the automatic P-381, built on a Soprod base and visible through a sapphire caseback. The 44 mm case is water resistant to 50 m.

The Skeleton also comes in plain steel (A1082/1) and in black PVD steel without the gold bezel (A1081/1). The standard Turbine (A1064/5) is the same 44 mm size in steel without the open dial, 13 mm thick against the Skeleton's 13.3 mm. The Turbine XL (A1050/1) and Pilot (A1086/1) go up to 48 mm.
