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.

Vermeil

Vermeil

A process or technique that involves coating a base metal, typically sterling silver, with a thick layer of gold using electroplating. The gold layer in vermeil is usually thicker than regular gold plating and is typically of a reddish hue (often 19-karat gold, containing 80% yellow gold and 20% other precious metals). This results in a more durable finish with an appearance resembling that of pure gold.
