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.

Super Luminova

Is a luminescent material used to enhance the visibility of watch elements when there are no external light sources available.

It is applied to the hands, hour markers, and other components of the watch, depending on the type of watch and its available functions. This material absorbs light energy from the surrounding light sources and stores it. In dark conditions, the stored energy is emitted as a visible glow, aiding in the visibility of the watch elements in the dark.
