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.

Brushing

Brushing, also known as satin finishing, is a technique used to create a specific pattern resembling a fabric texture on the surface of watch components. It involves the use of a brush or abrasive material to create parallel and fine lines.

Typically, the brushing technique is applied to metal surfaces, such as stainless steel or titanium, although it can also be used on other materials like gold or platinum. It is commonly used on watch cases, bracelets, and dials to enhance their appearance and create a distinctive visual effect.

The brushing technique involves creating fine and evenly spaced lines that can be horizontal, vertical, or diagonal, depending on the desired effect. These lines give the surface a textured and satin-like finish, adding depth and visual interest to the watch.
