What to know
The DB28XP Steel Wheels Tourbillon combines De Bethune’s openworked delta bridge with blue titanium surfaces and mirror-polished metal. Floating lugs adapt the watch’s stance on the wrist, while the crown at noon preserves the symmetrical outline. At 43mm across, the titanium case is only 9.1mm thick.
The hand-wound DB2009V6 movement pairs a thirty-second tourbillon with twin barrels and a five-day reserve. A reserve indicator sits on the reverse, keeping the front focused on the exposed mechanics. Released in late 2024 and profiled in January 2025, this ten-piece edition develops both the extra-thin DB28XP and the earlier Steel Wheels design.
