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.

KOLLOKIUM

Kollokium was founded in 2020 by three friends. After having collectively spent a lifetime contributing to the creations of numerous watch brands, Manuel Emch, Barth Nussbaumer and Amr Sindi’s mutual desire to build something from scratch became too strong to ignore. To create with no established or inherited framework. No existing brand, no defined artistic direction, no rehashed history, no constraints. The freedom to truly, fully manifest objects they envision without the compromises of structure. Positioned as a creative venture rather than a conventional brand, this eclectic approach mirrors its founders, all industry insiders hailing from various realms of watchmaking. Manuel Emch, a seasoned manager currently heading Louis Erard and Raketa, is equally renowned for his leadership roles at Jaquet Droz, where he became the youngest CEO in the Swatch Group at that time, and RJ-Romain Jerome. Barth Nussbaumer, a versatile designer with a diverse portfolio spanning from TAG Heuer to Petermann-Bedat, contributes his creative expertise. Amr Sindi, recognized as The Horophile, serves as an influencer and media consultant, adding a unique perspective to the team.
