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.

Tonneau

Tonneau

Is a watch case design that features a distinctive barrel or elongated rectangular shape with curved sides. It is characterized by its curved profile, which provides a unique and elegant aesthetic. The term "tonneau" is derived from the French word for "barrel," reflecting the shape of the case. Tonneau cases are often associated with vintage and luxury watches, and they offer a stylish alternative to traditional round or square case designs.
