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.

Case

Case

The case is the outer structure of the watch, including the bezel, back cover, face glass, and additional components such as the buttons and crown. It protects the internal components of the watch, including the movement, hands, and indices.

The case is typically made from materials such as stainless steel, gold, platinum, titanium, or ceramic, and may feature various finishes, such as a polished finish, brushed finish, or a combination of the two. The shape and design of the case vary depending on the style and purpose of the watch, ranging from traditional round cases to square, rectangular, or asymmetrical designs.

The case plays a crucial role in protecting the watch from external factors like moisture, dust, and shock. In addition to protection, the case also contributes to the overall aesthetic and style of the watch. It often includes details such as embossed markings, logos, or decorative elements. Case size and thickness can vary, affecting the overall dimensions and wearability of the watch.
