Roger Dubuis Excalibur Biretrograde Perpetual Calendar Review
The Roger Dubuis Excalibur Biretrograde Perpetual Calendar blends the brand’s signature biretrograde calendar format with the modern Excalibur case, delivering a lavishly layered dial featuring “Astral Blue” mother‑of‑pearl inlays, a striking pink‑gold moon phase, and finely finished snail cams for day and date. Housed in a 40 mm 18k pink‑gold case with a sapphire crystal and 100 m water resistance, the watch incorporates the new RD850 movement, which offers a traditional gear train, a 60‑hour power reserve, and enhanced reliability through jewelled bearings and polished bridges. The design’s bold aesthetic, including a controversial third lug and a serrated bezel, emphasizes both exclusivity and technical excellence, positioning the piece alongside other high‑end Geneva‑sealed perpetual calendars from brands like Piaget and Vacheron Constantin. Limited to 188 pieces and priced at US $109,000, the Excalibur Biretrograde Perpetual Calendar is available exclusively through Roger Dubuis boutiques. Its intricate finishing, automatic winding, and comprehensive complications—hours, minutes, seconds, perpetual calendar, retrograde day and date, and moon phase—highlight the brand’s commitment to haute horlogerie while offering a modern, reliable timepiece for discerning collectors.
Buying Time Analysis: This review highlights the Roger Dubuis Excalibur Biretrograde Perpetual Calendar as a pivotal example of haute horlogerie, marrying the brand’s historic biretrograde design with modern technical advancements and luxurious craftsmanship, underscoring its significance in the luxury watch market.
