Franck Muller Cintrée Curvex 'Casablanca'

In the world of haute horlogerie, where time is not merely measured but celebrated, Franck Muller remains something of an overlooked luminary. Founded in 1991, the brand set out with a clear vision: to elevate timekeeping to an art form, blending serious mechanical watchmaking with bold expressions of individuality. Few collections embody that philosophy better than the now-iconic Cintrée Curvex line. Introduced during the creative surge of the mid-1990s and early 2000s, these distinctive 'tonneau-shaped' watches walk a careful line between classical watchmaking and playful design. Often referred to as the “Master of Complications” (the title even appears on the caseback), Muller built his reputation on watches that were both technically accomplished and visually unmistakable. This example, reference 5850 Q 24, showcases that signature aesthetic beautifully. The curved 18k yellow-gold case measures 32mm by 40mm and sits comfortably on the wrist while delivering the architectural presence that defines the Cintrée Curvex. The dial is a two-tone silver guilloché (engine-turned) composition featuring center seconds, a date display via an inner graduation with central index, and a 24-hour AM/PM indication distinguishing daytime and nocturnal hours through a subsidiary dial at 6 o’clock. Large stylized numerals and sweeping hands reinforce the brand’s playful yet refined design language. This piece is part of a numbered limited edition, marked No. 09, adding an extra layer of collectability for those who appreciate early-era Muller production. Even better, it comes as a complete set, including the inner wooden presentation box, outer box, signed Certificate of Origin dated 2006, and service records from the mid-2000s — an uncommon level of documentation that speaks to careful stewardship over the past two decades. Inside beats the automatic Caliber 2800, providing reliable performance beneath the sculptural exterior. Paired with a leather strap and secured by an 18K yellow-gold pin buckle clasp, the watch is signed across the dial, case, and movement. A quintessential example: confident, expressive, and unmistakably Franck Muller!
