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.

Micro Rotor

Micro Rotor

A micro rotor, also known as a miniature oscillating weight, is a balanced rotating component commonly found in automatic and self-winding watches. It rotates with the movement of the wearer's wrist, continuously winding the main spring of the watch. This allows the watch to operate without the need for manual winding or hand winding. The micro rotor can rotate in one direction or bidirectionally.

The micro rotor is typically installed in the back part of the watch and is often visible through a transparent glass. It is considered an advanced technology in watchmaking, offering a combination of elegance and mechanical performance.
