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.

Co-Axial

The Co-Axial is a mechanism used in Omega watches. It is an innovative gear system characterized by non-parallel axes that connect the main gear train with the escapement wheel. These axes are precisely adjusted to reduce friction and wear resulting from the continuous movement of the watch, thereby improving timekeeping accuracy and increasing the lifespan of the movement. This mechanism was developed by the british inventor George Daniels.
