The Excalibur Bi-Retrograde Calendar by Roger Dubuis

This year, Roger Dubuis celebrates its 30th anniversary, and for the occasion, the company pays tribute to its co-founder’s favourite complication: the bi-retrograde display.

This function, previously featured in the Excalibur Grande Complication alongside a dozen other highly complex mechanisms, takes centre stage once again. The Maison has also introduced a less complicated, more classic edition to further honour the bi-retrograde display.

Also referred to as “the ecliptic counters” by the Maison a nod to their elliptical shape and distinctive role in indicating the months and date the design showcases a symmetrical dial layout. Enhanced by refined detailing, it pays homage to the Maison’s early creations from 1996.

Cabochon

Cabochon

Is a specific style of gemstone characterized by a rounded, convex, and polished top surface without facets. The bottom side of the gemstone is usually flat. Cabochons are created from various gemstones such as sapphires, emeralds, or even semi-precious stones like Yemeni agate or mother-of-pearl. The cabochon style is often used as a decorative element on the crown, pushers, or as hour markers on watch dials.
