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.

Sterling silver

Sterling silver

Is an alloy composed of 92.5% silver and 7.5% of other metals, typically copper, to increase its hardness. Sterling silver is known for its lustrous appearance and elegant beauty. It is used in the manufacturing of watch cases, bezels, and bracelet links.

Sterling silver is softer than stainless steel and requires proper care and maintenance to preserve its beauty.
