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.

Dual-axis tourbillon

Dual-axis tourbillon

Is an innovative and advanced complication of the traditional tourbillon mechanism, designed to improve the accuracy of time display by compensating for the effects of gravity. What sets the dual-axis tourbillon apart is the additional rotational axis, allowing the entire tourbillon assembly to rotate in two different directions simultaneously. This enhances precision and performance in watches, while also showcasing exceptional craftsmanship in the watchmaking industry.
