The Turbine Pilot Collection, by Perrelet

The Turbine Pilot collection is an incursion by Perrelet into the realm of the circular aviation slide rule mechanism.

Each timepiece comes in a stainless or steel black PVD case, measuring 48 mm x 13.6 mm, with an AR-coated sapphire crystal, a sapphire crystal display back, and is water resistant to 50 meters. There’s a crown at the watch’s 3 o’clock that activates the bidirectional rotating dial ring, with the time being set with an integrated crown at 9 o’clock.

The movement is an automatic P-331 caliber, developed in-house by the Swiss company, which is adorned with 21 jewels and beats at 28,800 vph, with 40 hours worth of power reserve.

The black dial features 12 titanium blades and has luminescent white hour-markers, as well as four applied Arabic numerals. All of this is set over a yellow and black background. Finally, the Perrelet Turbine Pilot watch comes with a black rubber or calf leather strap with contrasting grey stitching and a steel or steel black PVD buckle.
