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.

Mercedes Hands

Rolex sports watches, such as the Submariner and the GMT-Master, use "Mercedes" hands as a design feature. These hands derive their name from Mercedes Gleitze, a young British secretary, who etched her name in watchmaking history through a noteworthy feat. During her swim across the English Channel in 1927, the 26-year-old wore a Rolex Oyster, enduring over 10 hours in the cold waters between France and Great Britain. Following the swim, the waterproof wristwatch was proclaimed to be in a working condition, marking a significant moment in horological innovation.
