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.

Incabloc

Is a popular type of shock absorption system used in mechanical watches. It helps protect the delicate parts of the watch movement from sudden shocks and impacts. The system consists of a small spring and a jewel that are designed to absorb the energy from external shocks. The spring holds the jewel in place over the balance wheel staff, allowing it to move and shift when the watch experiences a sudden jolt or impact. This helps prevent damage to the delicate components of the watch, ensuring its smooth operation and longevity.
