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.

Malachite

Malachite is a type of gemstone known for its vibrant green color and unique natural patterns and designs, making it a beautiful artistic piece. It is used to decorate watch dials, watch bezels, and other elements of the watch.

Malachite is carefully cut and polished to achieve a smooth and shiny surface, allowing it to be perfectly fitted in the watch.

In addition to its natural beauty, malachite is also considered a symbol of protection, healing, and spiritual balance. Therefore, malachite can be added to watches as a symbol of strength and inner peace.

It is important to handle malachite with care to preserve its beauty and avoid scratches or damage. A special protective coating may be used to protect the surface of malachite and extend its lifespan in the watch.
