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.

Helmut Sinn, a former World War II pilot, established the company "Sinn Spezialuhren" in Frankfurt am Main, Germany, in 1961. The company primarily focuses on crafting navigation clocks and pilot chronographs.The Sinn 103 stands as one of the earliest models in the brand's lineup, dating back to the 1960s as a classic pilot's chronograph equipped with hand-wound calibers. Now, the brand releases the newest limited edition timepiece that adheres to that tradition, marking the first manual-wind 103 chronograph in two decades, the 103 St Ty Hd.

The timepiece is housed in a 41mm stainless steel case, boasting a thickness of 14.8mm and featuring a domed acrylic crystal. The black-coated bidirectional bezel includes a Super-LumiNova triangle and a fully graduated 60-minute scale. The watch is equipped with a push-pull crown and non-screw-down pushers, maintaining its pressure resistance of up to 200 meters.

The Tri-Compax chronograph showcases a 30-minute counter positioned at 3 o'clock, a 12-hour counter at 6 o'clock, and a small seconds subdial at 9 o'clock, all set against a matte black dial. The symmetrical V-shaped layout of the counters in a matte-silk light yellow hue creates a harmonious and innovative design. Additionally, the first ten minutes are alternately indicated in black and red. The dial is adorned with faceted hour and minute hands, designed with a luminous effect to ensure legibility even in low-light conditions. Additionally, the interior bezel hosts a tachymeter scale, measuring speeds ranging from 60 km/h to 600 km/h.

The timepiece is powered by the Sellita SW 510, a hand-wound movement operating at a frequency of 28,800 vph (4 Hz) and boasting a power reserve of 58 hours. The watch comes with a green boar leather strap featuring red contrast stitching, as well as a black boar leather strap with decorative perforations and white contrast stitching. It is limited to 1,000 pieces and is priced at EUR 2,590, equivalent to AED 10,250.
