A reference you don’t often see, this is a Franck Muller Master of Complications Regulateur, Ref. 7501 SR, crafted in 18k white gold. Its silver-toned regulator dial has beautiful guilloché detailing, and features a subsidiary hours dial at 12 o’clock and a subsidiary seconds dial at 6 o’clock. The minutes are elegantly tracked by the central hand, sweeping across the outer minute ring with blue Arabic numerals at five-minute intervals.

The case, in Franck Muller’s iconic Cintrée Curvex silhouette, measures 29mm x 39mm and houses the manual-wind movement Calibre 7500. This example comes fitted on a steel deployant buckle and is accompanied by its Certificate of Guarantee and leather pouch.
