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.

Tapisserie

Is a decorative technique commonly used in luxury watches. It involves engraving or carving a pattern of small, closely interlocking squares or rectangles on the watch dial. This intricate process is carried out manually using specialized carving tools or machines to create the complex design on the dial.

One prominent example of the Tapisserie technique can be found in the Audemars Piguet Royal Oak collection, where the brand introduced the famous "Grande Tapisserie" pattern. This pattern features a distinctive square or rectangular grid design that adds a unique and elegant character to the watch dial.
