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.

Anthracite-colored watch dials or watch components have a distinct appearance that can vary depending on lighting conditions. The term is commonly used in the watch industry to describe certain watch elements, especially dials and cases, that exhibit this dark and sophisticated color. Anthracite is favored for its versatility and ability to complement both formal and casual styles. It provides an alternative to traditional black or silver tones, adding depth and elegance to the overall design of timepieces
