De Bethune has since its inception in 2002 been a potent mix of ancestral horological know-how applied to cutting edge movement and avant-garde designs.

Denis Flageollet, the brand’s co-founder and master watchmaker rather than simply modifying or improving traditional techniques takes a precise mathematical and scientific approach with regards to the technical process, case and movement architecture, and finishing of each of his watches. All this results in some of the most visually striking and masterful products in contemporary horology, the present DB28 "Kind of Blue" Tourbillon is part of this elite circle.

Launched in 2016 the DB28 "Kind of Blue" Tourbillon features a striking heat blued titanium case and movement with the brand's signature delta shaped bridge decorated with applied microsphere stars in white gold. The hours are marked by arrow pointers in pink gold as are the skeleton hands. The sense of detail can be found in the pink gold back bezel and even in the prong of the pin buckle.

The watch features a 30seconds tourbillon, which is the lightest in the world, weighing 0.20 grammes for 63 parts. It also features a silicon balance wheel and escape wheel, the DeBethune proprietary balance spring with flat terminal curve, a self-regulating twin barrel to ensures constant torque in the movement.

Highlighting the ultimate rarity and desirability of this watch in the past 7 years only 8 pieces have been made.
