Celebrating 30 years of the Maison’s journey, this creation is a tribute to Mr. Roger Dubuis, who dreamed of crafting timepieces that cannot be found anywhere else. Rewarded by the prestigious Poinçon de Genève, the watch reveals unexpected aesthetics and the combination of a perpetual calendar, a minute repeater and a tourbillon.A Grande Complication is any watch fitted with at least three additional functions. The Maison delivered its first version in 2009, and this newly released Excalibur Grande Complication yet again demonstrates a commitment to savoir-faire, expressivity, and excellence, while celebrating the Maison’s 30th anniversary. This complex timepiece includes a flying tourbillon for gravity-defying precision; a Minute Repeater that chimes the controversial “devil’s chord”; and a perpetual calendar, which automatically adjusts itself for leap years and months with 28, 30, or 31 days. Mr. Roger Dubuis co-patented his own retrograde display in the 1980s, and today, the Maison has revived it with two scales in the signature Roger Dubuis shape. The open-worked dial and overall fine aesthetics add to the expressive design.Case Pink Gold case Pink Gold bezel Pink Gold crown Pink Gold open case back Sapphire crystal with anti-reflective coating Size: 45mm Water Resistance: 5 bar (50 m) Dial Double surface flange, ridged black top and white polished slope, with transferred minute track, polished and gold-plated hour markets with white SLN in the center.
