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.

Carl F. Bucherer is a Swiss luxury watchmaker renowned for its high-quality timepieces. The company was founded in 1888 by Carl Friedrich Bucherer in Lucerne, Switzerland. Throughout its history, Carl F. Bucherer has upheld a reputation for excellence in watchmaking craftsmanship and innovation.

In 2019, the brand introduced the Heritage BiCompax Annual, a timepiece that pays homage to the distinctive design ethos of the 1950s. This piece has become one of the brand's best sellers, embodying CFB’s commitment to craftsmanship. Now, Carl F. Bucherer adds a new silver-gray dial to the along with a new strap option.

The watch comes in a stainless steel case that measures 41 mm in diameter and 14.15 mm in thickness. The timepiece showcases a double-domed sapphire crystal, treated with anti-reflective coating on both sides, ensuring a clear display of the dial. The watch features a transparent sapphire crystal case back, giving us a glimpse of the movement.

The BiCompax dial design showcases two symmetrically arranged rhodium-plated sub-dials, with the small seconds positioned at 3 o'clock and the 30-minute counter at 9 o'clock. Additionally, the dial is encircled by a printed tachymeter scale and printed Arabic numerals, with a date window beneath the 12 o'clock marker and a month indicator frame positioned at 4:30. The watch displays both the month and date with an annual calendar complication that automatically counts months of different lengths, necessitating adjustment only once a year.
