The DeWitt DW8028s skeletonised movement uses age-old, recognised and highly reliable technical parameters in its construction: 18,000 Vph, a variable-inertia balance, a 44° angle escapement and a 72-hour power reserve.
Entirely produced in-house, this manually wound tourbillon is equipped with a Swiss anchor escapement and a Straumann Hairspring® with a Phillips terminal curve made from an unbreakable, self-compensating, non-oxidising, anti-magnetic alloy sequenced at 2.5 Hz. The perfect homogeneity and incredibly precise flat rolling of the hairspring (0.0001 mm) give the mechanism extremely high precision.
The Twenty-8-Eight Skeleton Tourbillon does not intend to compete with the ultra -skinny and fragile skeleton movements where as much material as possible has been removed. The architecture of DeWitt’s skeleton remains decidedly strong and is therefore very well balanced with the design of the case which features 48 imperial columns – a typical feature of practically all DeWitt masterpieces.
But however robust the foundations, your eyes will inevitably be drawn deep into the movement and the captivating finesse of its mechanics. You will marvel at the tourbillon as it rotates on its axis, held in place by a slender, black-polished, 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. As the barrel drum gently turns with the unwinding of the spring, the upper stems of this “vintage” wheel glide over the stems of the lower part – yet another interesting play on layers by DeWitt.
On the interior side of the bezel, a diamond-polished wall in 18-carat rose gold surrounds the movement above the skeletonised section, producing subtle reflections of this work of art. The wall is decorated by four extremely precise and sharp “W” logos, engraved on the cardinal points. The case is set with 36 baguette-cut diamonds and 96 brilliant-cut diamonds.
