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 to case and movement design architecture, manufacturing process, and finishing of each of his watches. All this results in some of the most visually striking and masterful products in contemporary horology.

Introduced in 2013, the DB28T “Black Gold” Tourbillon features an 18K pink gold case with polished zirconium articulating lugs. The watch features a 30-second tourbillon, which is the lightest in the world, weighing a mere 0.20 grams for 63 parts. It also features a silicon balance wheel and escape wheel, the DeBethune proprietary balance spring with flat terminal curve, and a self-regulating twin barrel to ensure constant torque in its power delivery. Each element of the movement exposed through the dial is meticulously finished.

Numbered 001, the present DB28T “Black Gold” is accompanied by its original accessories and preserved in excellent overall condition, from the collection of an astute connoisseur of independents.
