The Grand Complication Reference 5316 takes on a new contemporary look with a platinum case and a blue metallized sapphire crystal dial with a black-gradient rim. Manually wound R TO 27 PS QR combines a minute-repeater, a tourbillon and a perpetual calendar with retrograde date display and moon-phase indication – five of the most sought-after complications among connoisseurs. The original face of this new model is enhanced by a navy blue embossed calfskin strap with a fabric pattern, contrasting cream-colored stitching and a platinum fold-over clasp.
