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.

Mother of Pearl

Mother of Pearl

Mother-of-pearl, also known as nacre, is a composite material produced by certain freshwater mollusks as a thin layer or natural coating inside their shells. It is considered a precious and beautiful material.

Mother-of-pearl is used in watchmaking to decorate the watch dial, as well as other elements of the watch. It has a unique and multi-colored light effect, characterized by a pearlescent glow that changes with the angle of illumination and viewing, creating a distinctive and wonderful visual effect. Mother-of-pearl adds an elegant and feminine touch to watches and imparts a unique shine and beauty to the overall appearance of the watch.
