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.

Polishing

Polishing is a process in which the surfaces of watch components are polished. This technique is also used to remove scratches and surface defects from watch components, restoring their original shine.

This process is applied to various materials such as steel, gold, platinum, and others. Different materials are used to clean and polish the surfaces, whether they are metals, glass, ceramic, or other materials.

Polishing includes polishing watch cases, dials, front and back watch crystals, and other parts.
