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.

Tremblage

Is a decorative finishing technique applied to the watch dial, using a burin tool (a sharp-edged metal blade resembling a chisel) to create small indentations on the surface. The individual indentation is created by placing the burin tool at a specific point on the dial or component and striking it with a hammer. This motion is repeated on the surface to create a fully adorned pattern.
