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.

It is an independent organization responsible for testing and certifying the accuracy, precision and quality of mechanical watches. This organization cooperates with watch manufacturers to conduct rigorous testing on watches to ensure they meet the Master Chronograph standards.

These tests evaluate various aspects such as accuracy Timekeeping, resistance to magnetic fields, water resistance and durability. The certification denotes exceptional performance and quality, and watches that pass these tests receive a 5-year warranty.
