The Patek Philippe Nautilus reference 5711/1A-018 is a highly exclusive luxury sports watch created to commemorate the 170th anniversary of the partnership between Patek Philippe and Tiffany & Co. Limited to only 170 pieces, this model is distinguished by its vibrant Tiffany Blue lacquered dial, which features the double signature of both brands. The 40mm stainless steel case maintains the iconic rounded octagonal bezel and porthole-inspired construction, measuring a slim 8.3mm in height. The dial is adorned with blackened gold applied hour markers and baton-style hands, all fitted with luminescent coating for legibility, while a blackened gold frame surrounds the date window at the 3 o’clock position.

The timepiece is powered by the self-winding caliber 26-330 S C movement, which includes a 21k gold central rotor and provides a power reserve ranging from 35 to 45 hours. This movement features hacking seconds for precise time setting and is visible through a sapphire crystal caseback that bears the commemorative inscription 170th Anniversary – 1851-2021 – Tiffany & Co. – Patek Philippe. The watch offers a water resistance of 120 meters and is equipped with an integrated stainless steel bracelet featuring a folding clasp.

General reviews of the 5711/1A-018 often describe it as one of the most coveted and culturally significant timepieces of the modern era due to its extreme rarity and the legendary status of the collaborating houses. While horological critics note that the movement is mechanically standard for the Nautilus line, the aesthetic impact of the Tiffany Blue dial is widely praised for its boldness and modern appeal. However, the watch has also been a subject of discussion regarding the intense market speculation it generates, as evidenced by a single example reaching a multi-million dollar result at a charity auction. Despite its polarizing nature among traditionalists, it is regarded by collectors as the ultimate version of the discontinued steel 5711 series.
