The Aquanaut marked the beginning of a new generation of luxury sports watches for Patek Philippe, inspired by the unmistakeable lines of the Nautilus. In 1997, the manufacture introduced the ref. 5060, which was followed a few years later by the ref. 5066, which added an open caseback to the original design.
The Story of the Aquanaut
With the Nautilus having famously been penned by Gérald Genta, Patek Philippe decided to produce their own take on the luxury steel sports watch, designed entirely in-house. In 1997, they delivered the 5060A, which is widely considered as the first Aquanaut to have been introduced, integrating the signature elements that have endured to this very day: a stainless steel case, the recognisable checkerboard dial and a rubber strap.
These design elements were geared towards something much sportier and more contemporary than the manufacturer was then known for at the time. Though unconfirmed, rumour suggests that the model was first commissioned by high-level military personnel, hence the utilitarian design and dial pattern reminiscent of a grenade. Ever since its introduction, the Aquanaut has acted as a sort of modern canvas for experimentation, giving the manufacturer the ability to deviate from their otherwise reserved and classical offering.
A year after the model was first released, Patek Philippe introduced three more references, further developing their offering: the ref. 5064, with a practical quartz movement, the ref. 5065, which became the largest of the first generation Aquanauts and finally the ref. 5066, integrating an open caseback. The latter is the most faithful to the original Aquanaut design from 1997, whilst also offering the appeal of an open caseback.
A captivating design
With a texture reminiscent of a hand grenade, this military-inspired dial stands apart from the manufacturer’s more traditional designs. Each accurately bevelled brick gives a satisfying depth and definition to the otherwise pared-back colour scheme. This texture is extended over to the brick styled rubber strap, with both of them complementing each other and creating a general sense of coherence.
This early reference also features high contrast indices, hands and date wheel, which help with legibility, further proof that the watch was designed with usability in mind. The simplistic style of handset is still used to this day, showing a continuity from the earliest of designs. We also find polished and applied Arabic numerals, alongside a stark white seconds hand.
An interesting feature of this example is the tritium lume used on the hour markers, which has developed a warm patina over time. Patek Philippe used tritium between approximately 1998 and 2004, before transitioning to superluminova for their later pieces, between 2004 and 2006. Even if the tritium dials were used for longer, it is believed that Patek Philippe scaled-up production of the reference in the final two years, such that superluminova dials and hands are understood to be more common. Thanks to their tendency to develop patina with age, earlier examples have become particularly sought after, displaying some vintage elements which are lost on later pieces.
With finely polished edges and a flat, brushed bezel that frames the dial, well-executed finishing is found throughout the case. At 36mm, this watch wears well on a variety of wrist sizes, balancing its vintage and contemporary aesthetics. The watch has a heft and robustness about it, synonymous with sports watches. A highlight of the 5066 is the view into the inner workings of the watch, which is enabled by the addition of a sapphire caseback.
