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.

Platinum

Platinum is one of the rarest precious metals and is known for its exceptional durability. It is harder than gold and silver, does not tarnish, and has a brilliant white luster. It is classified as a noble metal due to its high resistance to corrosion.

Platinum is used in various aspects of watch design, including watch cases, bracelets, buckles, bezels, and other watch components. It is a popular choice for luxury watches, especially limited edition timepieces.
