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.

Stippling

A decorative technique used to create patterns that involve applying closely spaced small dots or small incised marks on the surface of a watch's enamel, case, or other components. This decorative pattern is achieved using specialized engraving tools. The craftsman carefully creates the desired pattern by applying precise and controlled strikes on the component's surface. The resulting effect is a series of dots or marks that create an attractive visual texture or design.

The choice of engraving pattern, density, and the size of the dots or marks can vary, allowing for a wide range of creative possibilities. Skilled craftsmen employ their expertise and artistic sensibility to apply engraving techniques in a precise and consistent manner, resulting in unique and visually appealing designs for watches.
