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.

Ornamental gems

Ornamental gems, also known as decorative stones, refer to precious stones used as decorative elements in watch designs. These gemstones are selected primarily for their aesthetic qualities and their ability to enhance the visual appearance of the watch.

Ornamental gems used in watches can include natural gemstones such as diamonds, sapphires, blue sapphires, emeralds, and pearls, as well as synthetic or imitation stones that mimic the appearance of natural gemstones. They come in various colors, shapes, and sizes to cater to different design preferences.
