A gorgeous watch by famed maker Franck Muller! The 18kt yellow gold Cintrée Curvex Master Calendar 5850, crafted in 2000, has a lovely tonneau shape and features a silvered guilloche enameled face. Concentric waves emanate from the center, shimmering beautifully as the watch is shifted. Large black numbers surround the face, the 2, 4, 8, and 10 replaced by black indices, the 3 and 9 not present as if they are out of frame. Royal blue numbers line the dial to indicate the date, the triple calendar completed by a rotating day-date and month. 5-minute intervals are detailed in red, separated by black markers to further specify the minute. "FRANCK MULLER GENEVE" and "SWISS MADE" are written in delicate black enamel while "MASTER CALENDAR" is marked in a matching red. The subtle blue steel watch hands tick smoothly as the internal automatic platinum movement runs. The weekday date, the day date, and the month are controlled by subtle buttons on the side next to the fluted crown displaying the Franck Muller logo The backside of the case is secured by four screws and is engraved with "FRANCK MULLER GENEVE Master of Complications № 173 5850 MC" next to a stamped "750" hallmark and a Swedish St. Bernard mark. A black alligator watchband, marked with a faded "FRANCK MULLER GENEVE" underneath, completes the look, its 18kt gold hardware marked with "750" and the Franck Muller logo. This watch is a beautiful example of Franck Muller's luxury timepieces and would be a phenomenal addition to any watch collector.
