The Excalibur Biretrograde Calendar is a celebration of Roger Dubuis’ 30th anniversary. The calendar is presented with elegant heritage materials, a classically refined size, and the esteemed excellence of Poinçon de Genève certification.

The face is in a symmetrical style, as it was in 1996, with the Biretrograde scales balanced on each side. The Small Seconds counter at 6 o’clock is aligned with the stamp at 12 o’clock. Featuring the BIRETROGRADE CALENDAR wording in the Maison’s historic font as well as the Geneva Seal emblem;  as it did in the Much More Biretrograde Calendar timepiece from the early 2000s. The 18K pink gold 40mm case with a white mother-of-pearl dial, is complemented by a 3D calf-skin leather strap in brown featuring an interchangeable pink gold triple-folding clasp.

The Biretrograde system requires a complex harmony of cams, rakes, clicks, and springs, which enable the calendar’s hands to move gracefully along the semi circle scales, and at the end of their cycle, return immediately to zero to begin their journey again.

The automatic Calibre RD840 movement is engineered with 60 hours of power reserve. Wearers can admire the mechanics inside and get a sense of the detailing that has been rewarded with Poinçon de Genève certification.  To reach the standard, every component in the Calibre RD840 has been decorated and polished by hand.

As a lasting tribute to the Roger Dubuis co-founders, a quotes appears on a ring beneath the sapphire glass. In classic handwriting style, this sentence has appeared on the oscillating mass of past Maison timepieces, giving it another authentic connection to this year’s anniversary. “C’est une montre actuelle, inspirée mais pas soumise au passé, qui se projette dans un futur qui nous appartient.” In translation, “This is a watch of today, inspired but not restricted to the past, projected into a future that belongs to us.”
