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.

Brilliant cut

The brilliant cut is a process in which diamonds used in watchmaking are cut to enhance the brilliance of the diamond set on the watch. It is one of the most famous diamond cuts, known for its ability to increase the visual properties and sparkle of the diamond.

The brilliant cut is characterized by its multiple facets, which are precisely arranged in a symmetrical pattern to optimize the reflection and refraction of light within the diamond. .
