Black variations on the DB28
Aesthetic BLACK
Sometimes mirror-polished for a shiny look, sometimes satin-brushed for a matt finish, black zirconium is a key element in the composition of the cases and floating lugs of the DB28 The multiple ways in which the light plays across the material and its various finishes reveal countless different tones ranging from anthracite grey to intense black. This pleasing aesthetic effect was already greatly appreciated on the DB28 dials, which opened a window onto the movement alternating between the sophisticated elegance of hand-polished bridges and the understated charm of Côtes de Genève reinterpreted by De Bethune.
Technological BLACK
In its research on materials and new processes, De Bethune saw the choice to machine zirconium as a natural and sustainable alternative for the colour black. The hardness of the metal as together stable oxidation that is unaffected by daily changes in temperature are twin assets that guarantee the resistance and durability of the exterior of a timepiece.
Adorned with its famous crown at 12 o’clock, the DB28 which is known for the surprising lightness of its case and the comfort of its floating lugs – a patented system that adapts to the size of the wrist and its various movements – is as supple as ever, since the lightness of titanium is replaced by that of zirconium.
New variations around a flagship model, featuring a contemporary design paradoxically inspired by that of historical pocket watches, highlight the technical breakthroughs achieved by the Manufacture and the meticulous decoration work of its artisans, custodians of age-old expertise.
DB28 Black matte– élégance sobre
Après avoir remporté en 2011 l’Aiguille d’Or, la plus haute distinction horlogère décernée par le Grand Prix d’Horlogerie de Genève pour son modèle DB28, De Bethune nous propose une déclinaison noire de son modèle emblématique. La DB28 est équipée du calibre DB 2115 qui bénéficie des innovations technologiques développées et produites au sein de la Manufacture. Une précision qui s'affirme via le double barillet autorégulateur et par la présence au sein de l'organe réglant du couple balancier silicium / palladium et spiral à courbe terminale plate, protégé par le système triple pare-chute.
A l’image de ce que l’on peut observer dans le ciel, les phases de lune se lisent par un affichage exclusif à l'aide d'une sphère en platine et acier bleui tournant sur son propre axe avec une précision de 1 jour toutes les 122 années.
