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.

Arnold & Son

Arnold & Son is a Swiss watch brand that was founded in 1764 by English watchmaker John Arnold. The company has a rich heritage in watchmaking and is known for its technical innovation and precision timepieces.

Arnold & Son watches are designed and manufactured entirely in-house. The brand's signature feature is the use of multiple complications in its watches, such as tourbillons and moon phases, all of which are expertly integrated into the design of each timepiece.

One of the most notable models in the Arnold & Son collection is the Constant Force Tourbillon, which uses a unique mechanism to maintain constant force to the escapement, resulting in unparalleled accuracy. The Globetrotter, on the other hand, is a world time watch that allows the wearer to keep track of the time in multiple time zones simultaneously.
