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.

German silver ( Nickel silver )

Nickel silver, also known as German silver, is a type of alloy commonly used in various components of watchmaking. Despite its name, nickel silver does not actually contain silver. It is composed of a mixture of copper, nickel, and zinc. The term "silver" refers to its silver-like appearance rather than its composition.

Nickel silver is used in different parts of a watch, including the case, movement plates, bridges, and other components. It possesses various properties such as corrosion resistance, durability, and ease of polishing.
