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.

brace or bridle

brace or bridle

Is a thin, curved metal piece used to support and secure the balance wheel and its associated parts. It is typically made of a durable and corrosion-resistant material such as steel or specialized watch alloys. The shape of the brace or bridle is designed to ensure proper alignment and stability of the balance wheel, allowing it to oscillate freely within its designated range. The shape and materials of the brace or bridle may vary in watches depending on the watch movement and design.
