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.

Eastern Pearl

A term used to describe a natural pearl that forms in nature without any human intervention or cultivation processes. These pearls are highly esteemed for their natural luster and rarity. Discovering a pearl with the characteristics of an "Eastern Pearl," which has fully developed on its own, is an exceptional occurrence. They are used in watchmaking for decorative purposes, adding beauty and luxury to the overall appearance of the watch.
