The movement of the Turbine Skeleton is Perrelet’s P-381. It’s an automatic caliber, beating at 4 Hz, with a 42-hour power reserve. Through the sapphire crystal caseback, you can see the skeletonized rotor with the Perrelet logo on it.
The P-381 is brand new: it’s a skeletonized version of Perrelet’s P-321 movement. Perrelet refers to the P-381 as an “in-house” caliber; it is likely a skeletonized variant of the Soprod A10 movement, which Perrelet has used in the past. (Perrelet and Soprod are sister companies within the Festina Group, so the movement is functionally “in-house.”)
All of the watches are available on a black rubber strap or a composite strap made of polyurethane and calfskin. All straps are black and fit seamlessly into the lugs. They have stainless-steel pin buckles with black coating.
There are three versions of the watch: the black and silver-colored ones shown above, as well as one with a rose-gold bezel. On the rose-gold Turbine Skeleton, the dial is again in black, but the even-numbered hour numerals are applied to a matching rose-gold backing. Hands and the dial’s center are also traced in rose gold.
The Turbine Skeleton will be available after Baselworld. The silver-colored version costs $7,250 on a rubber strap or $7,400 on the composite. The black version is $7,450 (rubber) or $7,600 (composite). With the rose-gold bezel, the Turbine Skeleton costs $9,450 (rubber) or $9,600 (composite).
