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.

Analog/Digital (or anadigi)

Analog/Digital (or anadigi)

An analog/digital (or anadigi) display is a type of display that combines elements of both analog and digital displays. This type of display typically features a traditional analog dial or pointer, but also includes a digital readout to display additional information.

Anadigi displays are commonly used in watches, where they can show both the time in analog form (with hands pointing to the hour and minute) and also display the time digitally (using a numerical readout). This allows for a quick and easy way to check the time at a glance, while still retaining the classic look of an analog watch.
