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.

diamond-cut

multi-faceted indexes" describes watch markers (indexes) or hands or other parts that are crafted with multiple angled surfaces, similar to the facets on a diamond. The "diamond-cut" refers to the precise cutting process used to create these facets, which enhances light reflection and gives the markers a sparkling, textured appearance. This technique makes the indexes stand out visually, adding depth and brilliance to the dial. The multi-faceted design ensures that the markers catch and reflect light from different angles, increasing their visibility and aesthetic appeal.
