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.

Blue Lapis Lazuli

Blue Lapis Lazuli, also known as Lazurite, is a precious gemstone occasionally used in watchmaking to enhance the watch’s aesthetics. This stone is renowned for its deep blue hue, often interspersed with irregular lines or golden and white specks, giving it a distinctive and captivating appearance.

In watchmaking, blue Lapis Lazuli is primarily used as a decorative element, often featured in the dial or crown. Its rich color lends an air of luxury and sophistication, making it a popular choice for high-end and prestigious timepieces as a symbol of exclusivity and exceptional craftsmanship.

Lapis Lazuli stones are meticulously cut and polished to achieve a smooth surface suitable for integration into watch components. Due to its natural variations, each piece of blue Lapis Lazuli is entirely unique.
