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.

Bagnolet

Is a term used to refer to a specific type of watch movement, known as the Bagnolet calibre. The Bagnolet calibre is a historical mechanical movement that was commonly used in pocket watches during the 18th and 19th centuries. It is named after the French town of Bagnolet, which was known for its production of high-quality watch movements. The Bagnolet calibre is characterized by its compact size and simple construction, making it popular for use in smaller pocket watches. It typically features a manual winding mechanism and basic timekeeping functions, such as hours, minutes, and sometimes seconds. While less common in modern watches, the Bagnolet calibre holds historical significance in the development of watchmaking and represents a specific era in horological craftsmanship.
