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.

Round Cut

Round Cut

It is a type of cutting used for gemstones, characterized by a circular shape. It is one of the most popular gemstone cuts and is known for its symmetrical design, consisting of 57 or 58 facets. These facets work to reflect light, creating a brilliant effect that catches the eye.

The round cut is chosen because it gives the gemstone a classic and sophisticated look in a watch. Additionally, the round shape is versatile and complements various styles and designs of watches, making it a common choice among manufacturers and consumers.
