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.

It is known for its transparency, high hardness, and scratch resistance, making it an ideal material for protecting the watch face. The sapphire crystal provides a clear view of the watch's dial, hands, and details, giving it an elegant appearance.

The synthetic sapphire crystal exhibits high resistance to breakage and corrosion, allowing it to withstand daily use while maintaining its quality and clarity for a long time.
