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.

Anti-magnetic

Anti-magnetic

Is a feature or characteristic of a watch that allows it to resist or minimize the effects of magnetic fields. Magnetic fields can interfere with the proper functioning of a watch movement, causing inaccuracies in timekeeping. An anti-magnetic watch is designed with materials and components that are not easily affected by magnetic fields. It may include the use of anti-magnetic alloys, such as certain types of steel or non-ferrous materials, as well as additional shielding or protection measures. The purpose of an anti-magnetic watch is to maintain accurate timekeeping even when exposed to magnetic fields commonly encountered in daily life, such as those generated by electronic devices or magnetic closures.
