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.

Glossary

GMT

A GMT watch is a timepiece designed to display multiple time zones simultaneously, typically focusing on a primary local time and a secondary reference time. Its defining feature is an additional hand, often brightly colored for visibility, that indicates the time in a second time zone.

Additionally, it comes with a 24-hour bezel or scale, which allows users to easily differentiate between day and night in the reference time. In some models, the bezel can be rotated to track a third time zone, making GMT watches a versatile and practical choice for frequent travelers.
