The Franck Muller Long Island (Ref. 900 S6) is a magnificent synergy of mechanical watchmaking tradition and high-society Art Deco flair. This authentic ladies’ timepiece stands as an exquisite expression of the “Master of Complications'” signature design philosophy. Forged from solid 18-karat white gold, its elegantly curved, rectangular case measures a perfectly proportioned 23 mm × 32 mm, contouring seamlessly around the wrist for unmatched feminine comfort.
The pièce de résistance of this horological masterpiece is its radiant, silvered dial, decorated with a stunning, undulating guilloché texture that catches and plays with ambient light. This mesmerizing surface is beautifully contrasted by Franck Muller’s instantly recognizable, oversized stylized Arabic numerals and an elegant small seconds sub-dial located at the 6 o’clock position. Driven by a traditional, mechanical manual-wind movement, this watch is engineered specifically for connoisseurs who appreciate the tactile ritual of hand-winding a fine mechanical caliber. Kept in very good pre-owned condition and outfitted on a premium leather strap, it represents an investment-grade cornerstone of low-profile luxury.
The Architecture of Time: The Art Deco Romance of the Long Island Case and the Guilloché Canvas Franck Muller’s Long Island collection draws rich inspiration from the roaring 1920s and the geometric majesty of the Art Deco architectural movement. While many rectangular dress watches feature flat, unyielding geometries, Franck Muller revolutionized the rectangular shape by introducing a gentle, ergonomic curvature throughout the entire white gold case structure, ensuring it sits flat and comfortably on the delicate lines of a lady’s wrist. The dial layout serves as a textbook example of high-end horological dial design. The traditional engine-turned guilloché patterning originates from the center and ripples outward, visually grounding the oversized numerals that lend the watch its dynamic, playful charm. Complemented by heat-blued steel hands that offer a beautiful pop of royal contrast against the white gold backdrop, this 900 S6 reference is an elegant alternative to generic mass-production timepieces.
