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.

Autoquartz

Autoquartz

Is a term used to describe a hybrid watch movement that combines both automatic and quartz technologies. In an autoquartz movement, the watch is powered by a rechargeable battery, similar to a traditional quartz watch. However, unlike a standard quartz watch that relies solely on the battery for power, an autoquartz movement also incorporates a self-winding rotor. This rotor harnesses the natural motion of the wearer's wrist to generate electrical energy, which is used to recharge the battery.
