The Twenty-8-Eight Skeleton Tourbillon is housed in a 43 mm round case made of grade 5 titanium with blued hands or in grade 5 titanium with a chocolate-brown PVD coating. Presenting particularly comfortable proportions with redesigned lugs and slightly more discreet imperial columns displayed on its flanks, it remains instantly recognizable and true to DeWitt’s strong DNA.
The Twenty-8-Eight Skeleton Tourbillon does not intend to compete with the ultra-skinny and fragile skeletons where as much material as possible was taken out of the construction. The architecture of DeWitt’s skeleton remains deliberately strong and is therefore very well balanced with the design of the case which features 48 imperial columns.
The DeWitt calibre DW8028 uses age-old, recognized and highly reliable technical parameters in its construction: 18,000 A/h, a variable-inertia balance, a 44° angle escapement and 72 hours power reserve.
Entirely produced in-house, this manually wound Tourbillon is equipped with a Swiss lever escapement and a Straumann® hairspring with Phillips terminal curve made out of an unbreakable, self-compensating, non-oxidizing, anti-magnetic alloy and sequenced at 2.5 Hz. The perfect homogeneity and incredibly precise flat rolling of the hairspring (0.0001 mm) guarantee an extremely high precision.
The carved-out mainplate, a sand-brushed nickel silver base with black gold surface finishing and a yellow gold inscription of the calibre reference, is a marvellous labyrinth of curves, circles and straight lines. The tourbillon is held in place by a long, slender and circular-grained Art Deco bridge. The barrel, positioned at 12 o’clock, is also skeletonised in order to reveal the interior of the motor. The shape given to the open-worked barrel was inspired by the design of vintage car steering wheels.
The balance, as well as the escape wheel and the pallets are made of 18-carat yellow gold.
The Twenty-8-Eight Skeleton Tourbillon fully complies with the very demanding finishing norms of the DeWitt Manufacture. Case, plate, bridges, wheels and even miniature screws are all bevelled, polished, satin-finished and treated by hand.
