The Diver's version of Perrelet's Turbine is very special. It features a completely luminescent dial, on which the second rotor of the Perrelet P-331 calibre (based on the IWC-manufactured Alternance 10 calibre, decorated with côtes de Genève) rotates, visible through the sapphire crystal porthole on the back. Also protecting the dial is a sapphire crystal, which has undergone a double anti-reflective treatment. Still on the subject of the dial, it is worth mentioning the presence of the rotating flange, operated by means of the screw-locked additional crown positioned at 10 o'clock, while the winding and regulating crown is integrated into the case middle and positioned at 4 o'clock. Hands and hour markers are sprinkled with luminescent substance, making the indications very easy to read in all lighting conditions. The case, available in steel or steel with PVD-treated parts, has a diameter of 47.5 millimetres and a thickness of 14.82. Equipped with a rubber strap with a steel pin buckle, the Turbine Diver is guaranteed water-resistant to a pressure of 30 atmospheres.
Price: 5,200 euro.
