Descrizione dettagliata lotto
Highly attractive, the present platinum De Bethune DB25QPA perpetual calendar features highly legible indications, with the day and month displayed via apertures on the sides of the dial, the date positioned at 6 o’clock, and De Bethune’s signature three-dimensional spherical moon phase display, offering an exceptional accuracy of one lunar day every 122 years (patented 2004). A leap year indication is subtly integrated below the moon phase, represented by the eclipse of a star.
At the heart of this timepiece is the self-winding DB2324 calibre, which incorporates at least five of De Bethune’s patented innovations, each contributing to the brand’s renowned technical mastery. It boasts a five-day power reserve, powered by a self-regulating twin barrel (patented 2004); a titanium and platinum balance wheel (patented 2008); a silicon escape wheel; a triple pare-chute shock-absorbing system (patented 2005); and the De Bethune balance spring with a flat terminal curve (patented 2006).
