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.

Stamping

Stamping

A manufacturing process that utilizes specialized molds to shape metal components through mechanical force. The metal sheets or strips are pressed onto the molds, causing the metal to take on specific shapes or patterns. This method is used to produce watch components such as dials, cases, and bezels, providing cost-effectiveness and efficiency for mass production. Stamped components undergo additional finishing processes like polishing, coating, or engraving to enhance their appearance and functionality.
