Debuting in 1997, the Patek Philippe Aquanaut was released to engage with a new younger, sportier and trendier watch collector base that had found success thanks to the dot.com stock market explosion. Released under the same premise as the Nautilus in 1976, the Aquanaut was designed as a trendy watch for a new clientele. This caused the Aquanaut to raise suspicions from Patek's traditional collectors as it introduced a rubber strap to Patek's catalogue – something collectors saw as a cheap design option at the time. With the ref. 5167A's integrated black rubber strap and black embossed dial, this Aquanaut variant is a smart and stylish option for the collector who wants their timepiece to fly under the radar while still packing a hefty punch of horological history and an iconic design that has since become one of Patek Philippe's most emblematic offerings. Released in 2007, the ref. 5167A has emerged as one of Patek's most versatile offerings with its robust sports watch design and elegant aesthetic combining to create a timepiece that can be worn for most occasions and paired excellently with a wide variety of outfits.
