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.

Sapphire is a natural gemstone known for its deep red color and beautiful luster. It is considered one of the most precious gemstones and is highly popular in the luxury watch industry. Sapphire is used in several parts of the watch, including the watch case, the dial, and the control buttons. Sapphire is a hard and durable material, making it ideal for use in watchmaking as it provides high resistance to scratches and corrosion. In addition to its attractive beauty, sapphire is considered a symbol of strength and elegance.
