Watch of the Week: Patek Philippe Nautilus Ref. 5711/1P

The Swiss watch brand celebrates 40 years of its legendary Nautilus timepiece with this anniversary design.

This year is an exciting one for Patek Philippe as it marks the 40th anniversary of its iconic Nautilus timepiece. Ten months into 2016, and nearly seven since the brand first hinted at an exciting debut at Baselworld, Patek Philippe has just debuted two new watches in honor of the occasion.

The legendary, maritime-themed watch—see its porthole-style case shape inspired by the fine ocean liners of the time and the long lateral lugs on both sides of the case to emulate the lock and hinges of the porthole windows—was first unveiled to the world in 1976. As one of the first ever luxury watches to be presented in stainless steel, it was an immediate hit.  Throughout the past four decades, that signature shape has remained the same across numerous iterations of the watch, and that includes the two new anniversary pieces.

Our favorite of the pair, the Nautilus Ref 5711/1P, is crafted in solid platinum. Like the original Nautilus, this 44mm watch features the same ridged PVD blue-treated 18-karat gold dial. But for 2016, Patek adds 12 applied baton-shaped markers made of Top Wesselton baguette-cut diamonds, set in 18-karat white gold, and an embossed inscription that references the anniversary year.

Housed within the case is the in-house-made Caliber 324 S C, a self-winding mechanical movement consisting of 213 parts and 29 jewels. The high-tech movement, with patented Gyromax® balance, offers between 35 and 45 hours of power reserve and holds the Patek Philippe Seal, attesting to its benchmark craftsmanship and mechanics. Like its predecessor, the watch is sold in a specially crafted anniversary cork box, with just 700 pieces made in all. Price: $113,440;
