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.

Strap

A band made of materials such as leather, canvas, rubber, or other non-metallic materials. It is attached to the lugs of a wristwatch to secure the watch to the wearer's wrist, serving as an alternative to a metal bracelet.

The strap is designed to provide comfort and flexibility while keeping the watch securely in place. It can be adjusted to fit the wrist size and often features a buckle or clasp for easy fastening.
