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.

The railtrack road design is applied to the main dial and sub-dial of a watch, inspired by the parallel tracks of a railroad. It consists of marks or minute lines resembling railroad tracks that encircle the edge of the main dial or sub-dial. The minute markers in this design are spaced evenly and often used to indicate the minutes on the watch, providing an accurate and clear time display. The railroad track design is commonly seen in classic and formal watches, adding a touch of elegance and sophistication to the timepiece.

The name railtrack road comes from its historical association with the railroad industry. In the past, precise timekeeping was crucial for safe and efficient train operations, and train engineers used pocket watches specifically designed with the railroad track design to ensure timing accuracy.
