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.
This DB28 is equipped with DB caliber 2115 which is endowed with the technological innovations developed and produced within the manufacture. Its precision is further consolidated by the self-regulating twin barrel and by the presence within the regulating organ of a silicon/palladium balance wheel and a balance-spring with a flat terminal curve, protected by the triple pare-chute system.
As one can see from careful observation of the sky, moon phases are read off on an exclusive display by means of a platinum and blued steel sphere spinning on its axis and boasting a degree of precision equivalent to a mere one-day difference every 122 years.
