A collector’s dream come true, this 40th anniversary edition is the rightful heir of the original Nautilus of 1976 by Patek Philippe. Crafted in solid platinum and limited to just 700 watches, Ref. 5711 displays the subtle evolution of the model over the last four decades and, in keeping with the current vogue for larger watches, has a diameter of 44mm. The dial, made of 18-carat gold features a dark blue hue with a bright to dark gradation from the centre to the periphery of the dial. Baguette-cut diamonds are used as hour markers and the horizontal embossing on the dial bears the anniversary citation “40” and “1976-2016”. Equipped with automatic caliber 324 SC, the heavy central rotor in 21-carat gold delivers the power needed for fast and reliable winding and, along with the beautifully finished touches on the movement, are visible through the sapphire crystal caseback. Each watch is individually numbered and comes in an anniversary box made of natural brown cork, an authentic replica of the 1976 original.
