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.

It's the process of applying numbers, symbols, or indicators onto the dial of a watch to indicate the time or other functions. These markers are typically designed in a decorative manner to add an aesthetic touch to the dial and the watch as a whole.

Applied markers in watches are typically made from Superluminova, Tritium, or metal, and sometimes diamonds or gemstones.
