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.

UTC

Coordinated Universal Time, is a globally recognized standard for time coordination and synchronization. It is based on atomic time and serves as a reference for various industries worldwide. Unlike local time zones, UTC is not linked to specific regions and remains constant. It is represented in a 24-hour format using digits only and allows for accurate timekeeping and coordination across different locations. UTC is widely used in telecommunications, aviation, computing, and other fields to ensure precise time synchronization and facilitate international communication and event planning.
