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.

Pin buckle

Pin buckle, also known as tang buckle, is a metal frame with a pin (tongue) attached to one end of the watch strap and a series of holes on the other end of the strap. It is used to securely fasten the watch strap around the wrist. It is one of the traditional and simple closure mechanisms commonly found in various watches. The pin buckle is secured by inserting the pin into the designated hole, allowing the wearer to adjust the fit according to the size of their wrist.
