Since its introduction in 2007, the popularity of the Aquanaut 5167A has followed on the coattails of the Nautilus Ref 5711/1A. And now for the occasion of the Watch Art Grand Exhibition in Singapore, Patek Philippe has unveiled a special-edition Aquanaut ref. 5167A-012 with red accents and a red strap.

The dial features the Aquanaut’s traditional chequerboard motif, but with red minute markers and a red central hand. The addition of colour is a nod to Singapore’s flag, which is red and white. Though the cosmetic changes are minimal, the overall effect of which is nonetheless striking and appealing.

Depth rated to 120m, the case remains 40mm in diameter and is paired with a red composite strap. It houses the cal. 324 S C, which is visible through a sapphire case back that has been printed with the inscription “Patek Philippe Singapore 2019”.

The cal. 324 S C is the brand’s central-rotor automatic movement that is fairly ordinary but attractively finished. It offers a short 35- to 45-hour power reserve, and as with all of Patek Philippe’s current movements, it is fitted with a Gyromax balance wheel, which is essentially a free-sprung, adjustable mass balance, as well as a silicon Spiromax hairspring.
