Aquanaut Patek Style — 40mm Automatic Sport Watch, Five Dial Options
A 40mm automatic sport watch with a bold square case in stainless steel, 13mm thick, in five dial options: Blue, Black, Green, Orange, and Rose Gold. The Aquanaut-inspired square case design with sport-integrated proportions — a nautical aesthetic in a robust automatic package.
Key Specifications
What Makes It
Square Sport Case
The square case shape in the Aquanaut tradition gives this watch an architectural presence on the wrist that a round case cannot replicate. Bold geometry, sport proportions, and the nautical sport watch heritage it draws from.
Five Dial Options
Blue is the reference nautical colourway. Black is the most versatile. Green is the collector's choice. Orange is the boldest and most distinctive — rare on a sport automatic at any price. Rose Gold adds warmth.
Automatic Movement
Self-winding automatic movement — no battery, no winding required during regular daily wear. The movement winds from natural wrist movement over the course of the day.
Stainless Steel Construction
Stainless steel case with robust 13mm thickness — this wears as a purposeful sport piece rather than a thin dress proposition. Built for active daily use.
The Aquanaut-style square sport case is one of the most distinctive silhouettes in modern luxury sport watchmaking — a bold departure from the round case majority, with flat sides and integrated sport proportions that were designed for water and outdoor use from the beginning. Five dial options on the same 40mm steel case gives you substantial choice without changing the fundamental character: Blue is classically nautical. Black is the most universally wearable. Green is the current collector's favourite in sport watches. Orange is the most striking option on the market in this case format at this price. Rose Gold is warm and unexpected on a sport case architecture that typically trends toward cooler metals.
The 13mm thickness places this firmly in the sport watch category — it has wrist presence and sits with authority rather than disappearing. An automatic movement in a square sport case at this price is an unusual value proposition.
Styled For
Sport and Nautical
The Aquanaut design heritage is nautical in origin. Blue is the natural choice; all five dials carry the same robust sport-case specification.
Smart Casual
A square-case automatic in a non-round format is a statement choice that reads as design-aware at close inspection.
Collectors
Orange on a square sport automatic is an unusual and bold collector proposition. Green is the more mainstream collector's choice in the current market.
Gift
Five colour options and an automatic movement in a distinctive square case make this a strong gift choice for someone who follows watch design.
