 De Bethune – DB Kind of Grande Complication 

Encapsulating the memory and culture of De Bethune in an exceptional timepiece that illustrates the technical and artistic expertise and excellence cultivated in its L’Auberson workshops was the challenge taken up by Denis Flageollet and his high-flying team. 

The case incorporates a rotation system (feature introduced in 2021) mounted on floating lugs which – by means of an ingenious micro-mechanism – enable the case to pivot around its central axis in a smooth, accurate swivelling movement. More than 60 components – 50 of which relate to the water-resistant part and are therefore perfectly rustproof – are involved in positioning the dial on either side. A cam-operated indexing system ensures perfect alignment of the case with the floating lugs that follow the curves of the wrist.

The rounded design of its classically inspired case with its crown at 12 o’clock on the contemporary side (6 o’clock on the traditional side) conceals the technical challenges of a double case complexified by a multiple display of several functions and the combination within a single calibre of eight different horological complications: perpetual calendar, spherical moon-phase indication, retrograde age of the Moon and leap years, ultra-light tourbillon in blued titanium, jumping seconds, power reserve as well as the double display of hours and minutes.
