The De Bethune DB29 Maxichrono Tourbillon exemplifies the independent Swiss manufacture’s avant-garde approach to haute horlogerie. Presented at Baselworld, it showcases the brand’s signature multi-layered architecture and technical mastery — with a hidden tourbillon revealed only through the exhibition caseback. The 46mm 18K rose gold case frames a multi-level dial designed for optimal readability of complex chronograph indications. The outermost scale simultaneously serves three hands — minutes, chronograph seconds, and chronograph minutes — while the central ring displays the hours, and the innermost ring tracks chronograph hours, allowing measurement of up to 24 hours.At the heart of the watch lies the Calibre DB2039, a manually wound movement featuring a 30-second tourbillon that rotates twice as fast as a traditional one. The chronograph mechanism, controlled by three column wheels, operates independently from the tourbillon and is fully managed via a single pusher — a rare and ingenious configuration.
Limited to 20 pieces, the DB29 Maxichrono Tourbillon won the “Best Tourbillon” award at the Grand Prix d’Horlogerie de Genève (GPHG), solidifying De Bethune’s reputation for technical brilliance and artistic innovation.
