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.

Pivots

Pivots

Pivots are small cylindrical components that serve as bearings or shafts for the rotating elements in a watch movement. They are typically manufactured from durable materials such as steel or precious metals to withstand continuous friction and wear in the watch's mechanism. Pivots play a crucial role in facilitating smooth performance of gears, wheels, and levers within the movement by providing a stable and low-friction rotation point.
