The hour hand is translucent and made from blued-steel rimmed sapphire in order to view the movement. The hour markers, like previous DB28 iterations, resemble small ball bearings and are constructed of steel. At 6 o’clock, you can spot the steel moon phase that is made from two halves of palladium and blued steel. Blued steel is a full-fledged design code here as it also forms the chapter ring that runs along the edge of the dial and beneath the hour markers and ratcheted minute indices, the minute hand, and around the hour hand. Above the moon phase and beneath the center of the watch is a titanium, polished bridge that is situated above the balance wheel with gold weights. The case itself is entirely constructed of titanium meaning the timepiece is extremely lightweight. The watch is the same size as previous DB28 models, coming in at 42.6 mm.
Other details of the movement worth noting include the De Bethune balance spring with a flat terminal curve, a silicon escape wheel, a triple pare-chute shock absorbing system, and the aforementioned titanium balance wheel with white gold inserts.
The De Bethune Steel Wheels is priced at 83,000 CHF, approximately $88,340 USD at the time of publishing.
