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.

Pallet Fork

Pallet Fork

A component found in the escapement mechanism of a watch movement. It is responsible for engaging with the escape wheel, which regulates the release of energy to the watch's timekeeping mechanism. The fork consists of two curved arms that extend from a central pivot point and are designed to fit between the teeth of the escape wheel. As the balance wheel oscillates, the fork moves back and forth, interacting with the escape wheel to control the rotation and timing of the watch's gears. This precise and coordinated interaction between the fork and escape wheel is essential for the accurate and reliable timekeeping of the watch.
