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

Sapphire, also known as blue sapphire, is a precious gemstone commonly used in watchmaking due to its durability, hardness, and enchanting appearance. It is distinguished by its rich blue color, although it can be found in other colors such as pink, yellow, and green. Sapphire is highly valued for its scratch resistance, making it an ideal material for the glass crystals used in watchmaking. These crystals protect the watch face, providing clarity and transparency for easy time reading.
