De Bethune

Founded in 2002 by businessman David Zanetta and master watchmaker Denis Flageollet — nicknamed the 'Mad Professor' for his relentless pursuit of innovation — in L'Auberson in the Swiss Jura. Fewer than 4,500 De Bethune watches have been produced in its entire history, with annual production under 350 pieces. The brand seamlessly blends 18th-century craftsmanship with space-age engineering in a way matched by virtually no other independent. Flageollet worked with Vianney Halter before De Bethune, and Denis Flageollet is one of the few watchmakers who has contributed to the art of movement finishing while simultaneously advancing materials science.

Key innovations and patents: patented spherical moon phase (palladium and blued steel hemispheres, accurate to 1 second per year — first seen in DB15); patented hairspring with flat terminal curve (2006); patented titanium balance wheel with white gold inserts (2016, optimised for temperature and air resistance); patented triple pare-chute shock absorption; Côtes de Bethune decoration (a radiant variant of Côtes de Genève); heat-blued titanium cases and components (pioneered the controlled oxidation technique that gives De Bethune its unmistakable celestial blue); floating lugs (first on DB21 Maxichrono — skeletonised lugs connecting at 3 and 9 o'clock only, adapting to any wrist). The DB28 (2011, GPHG Aiguille d'Or — the 'Best Picture' prize of watchmaking) made De Bethune a grail brand: it introduced heat-blued titanium cases, floating lugs, and the signature 3D moon phase in an iconic round case with crown at 12 o'clock, inspired by pocket watches. DB25 won GPHG prizes in 2019 and 2021. Recent: DB Kind of Two GMT (dual dials, jumping hours, two time zones); DB25 Perpetual Sky; Louis Vuitton × De Bethune LVDB-03 (€4 million sympathique clock). WatchBox — now operating as The 1916 Company — acquired a majority stake in De Bethune in 2021, providing capital and global retail access while, by all accounts, leaving Flageollet with complete creative and technical autonomy; the brand continues to operate day-to-day with the independence and design DNA of its founding two decades ago. Pierre Jacques, CEO since 2011, stepped down in 2025 after fifteen years leading the brand's commercial growth, remaining involved as Honorary President; Justin Reis, co-founder of WatchBox, now serves as Executive Chairman alongside Flageollet.

What sets De Bethune apart even among grail-tier independents is how far its curiosity extends beyond its own catalogue. The Resonique programme, first presented in 2011, explored replacing the sprung balance and lever escapement altogether with an acoustic oscillator vibrating at 928 Hz — the equivalent of more than 6.6 million vibrations per hour — driven by a magnetic escapement; tellingly, Flageollet published the research and invited the wider watchmaking community to build on it rather than hoarding the work behind patents. The manufacture has run an industry first in field testing, equipping select customers' watches with sensors recording movement, shocks, temperature, humidity, and pressure in real wear. Collaborations read like a map of the brand's esteem among its peers: the one-off 'Kind of Magic' created jointly with Kari Voutilainen for Only Watch 2021, an hourglass project realised with designer Marc Newson, and — in February 2023 — the acquisition of a majority stake in Reuge, the storied Sainte-Croix maker of music boxes, automata, and singing birds founded in 1865, now run by the De Bethune team as a joint laboratory for what the brand calls art mechanics. The same year, Assouline published 'De Bethune: The Art of Watchmaking' by Arthur Touchot, with contributions from Jean-Claude Biver, Aurel Bacs, and Voutilainen — the coffee-table canonisation of a manufacture that, from its ateliers in the Sainte-Croix hills, has spent two decades proving that the 21st century's most forward-looking watchmaking can also be its most romantic.
