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.

Tungsten

Tungsten

Is a heavy and brittle metal with high density that is characterized by its shiny white color. Tungsten has the highest melting point and second highest boiling point of all elements. It is used in the construction of various watch components such as watch cases, bezels, and watch bracelets due to its scratch-resistant properties and its ability to maintain its polished appearance over time.
