Introduced in 2014, the Perrelet Turbine Yacht — another new complication for the distinctive Turbine collection, which has swiftly become Perrelet’s flagship family — combines the spinning dial-side turbine-style rotor with an integrated windrose function, inspired by the world of yachting, which helps to orient sailors by points of reference and the position of the sun. The Perrelet Turbine Yacht has a substantial, 47-mm-diameter stainless steel case, also available with either black or bronze-toned PVD coating. The turbine rotor on the dial, made of titanium, has 11 blades, echoing the look of a submarine propellor, and rotates above a surface with a maritime-themed parallel-line pattern reminiscent of the teakwood deck of a yacht. The windrose — according to Wikipedia, “a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location” — is on a bidirectional rotating ring surrounding the dial. prices for the Perrelet Turbine Yacht range from $6,550 to $7,200.
