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.

Liquid Crystal Display (LCD)

Liquid Crystal Display (LCD)

An LCD screen is a digital display used to show the time, functions, and other information on a watch using segmented numbers or a combination of numbers and alphabetic characters. These screens are made of liquid crystal material that alters its light-transmitting properties when an electric current is applied, resulting in the display of information.

Typically, the screen is backlit, allowing for easy readability in low-light or dark conditions. LCD screens are known for their energy efficiency, consuming lower power in general, which helps to increase the battery life of the watch.
