A sympathetic clock — a master clock that rewinds and corrects a watch placed inside it — is one of the rarest and most arcane ideas in horology. Invented by Abraham-Louis Breguet in the late 18th century, it has not been created in 35 years. Louis Vuitton and Denis Flageollet of De Bethune have now revived it — not as a museum throwback, but as a fully modern, technically evolved mechanical ecosystem: the LVDB-03 Louis Varius Project. Filmed in Tokyo at the project’s debut, Wei sits down with Jean Arnault and Denis Flageollet to unpack every element of this unprecedented collaboration — from the 60kg block of titanium machined into a marine-chronometer-inspired clock, to the triple-level rotating diorama carved by François Schuiten and Michèle Rothen, to the hidden sympathetic mechanism that winds and adjusts the wristwatch inside its capsule. They explain: • how the three-level diorama works (13-hour rotation, 1-hour rotation, constant scene changes) • why the golden globe is engraved with the Hercules constellation (the sky over Vuitton’s birth year, 1821) • how the capsule accepts the entire watch and strap — a first • how the coaxial pusher inside the crown adjusts the watch by ±7 minutes • why De Bethune’s signature flame-blued titanium and proprietary balance wheel define the mechanical language • why only 12 watches and 2 clocks will be made, each clock taking almost 4 years This project is more than a collaboration — it’s the preservation of endangered horological knowledge, and a continuation of Louis Vuitton’s mission to support independent watchmaking through the LV Watch Prize. This is the most ambitious mechanical object Louis Vuitton has ever created — and one of the most extraordinary feats of modern independent watchmaking.
