The Patek Philippe Nautilus Ref 5711/1A-010 is arguably the world’s most desirable steel luxury sports watch. And now it’s discontinued. The rounded octagonal shape of its bezel, the ingenious porthole construction of its case, and its horizontally embossed dial, the Nautilus has epitomized the elegant sports watch since 1976. Forty years later, it comprises a splendid collection of models for men and women. In steel, rose gold, white gold or two-tone combinations they accompany the most active lifestyles with incomparable class.   The blue dial of this luxury steel watch has been one that has been highly sought-after. This is a watch you would like to be in your collection. This watch is unworn and considered “New Old Stock” (NOS). It is in amazing condition and is available to purchase today.
