DeWitt Twenty-8-Eight Skeleton Tourbillon Set with Diamonds (T8.TH.022)

The Twenty-8-Eight Skeleton Tourbillon Set with Diamonds houses DeWitt calibre DW8028s, which 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 anchor escapement and a spiral 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 to the mechanism.

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 carved-out main plate, a sand-brushed nickel silver base set with 215 round diamonds, is an impressive labyrinth of curves, circles and straight lines. Meandering across the movement, the lucky observer will suddenly land on a stunning skeletonised “W” logo positioned at 9 o’clock. The play on depths, perspectives and layers is a typical feature of DeWitt designs and the Twenty-8-Eight Skeleton Tourbillon is no exception. The skeletonised “W” logo is actually duplicated on the lower part of the movement in order to offer these interesting volumes when admiring the movement from either side of the watch. But however robust the foundations, your eyes will inevitably be dragged deep into the movement and the captivating finesse of its ticking mechanics. You will marvel at the Tourbillon as it gracefully rotates on its axis, held in place by a long, slender and circular grained Art Déco 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. As the barrel wheel gently turns with the unwinding of the spring, the stems of the upper part will glide over the stems of the lower part.

The Twenty-8-Eight Skeleton Tourbillon is housed in a 43 mm round case made in 18-carat white gold. Presenting particularly comfortable proportions with redesigned lugs and slightly more discrete imperial columns displayed on its flanks, it remains instantly recognizable and true to DeWitt’s strong DNA. Its balanced design offers the necessary combination of character and refinement for a successful wedding with the architectural lines of the skeleton movement.
