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.

Striking mechanism

Striking mechanism

A complication in mechanical watches that produces audible sounds at specific time intervals. It is designed to strike or chime, adding an acoustic dimension to the timekeeping function of the watch. The striking mechanism typically consists of a set of hammers, gongs, and other components that work together to produce the sound. The hammers are responsible for striking the gongs, which are coiled wires or bars with specific lengths and tensions. When activated, the hammers strike the gongs, producing different tones or sequences of sounds.
