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.

vane

A vane is a rotating metal piece used to tell time. It is typically circular in shape and has a connected arm, which is linked to a mechanism that allows it to rotate and indicate the time. Vanes are commonly found in pocket and wristwatches. They are often adorned with intricate patterns, symbols, or complex images to add a distinctive decorative touch to their functional side.
