Rado Captain Cook R32136323, 42mm, Stainless Steel Bracelet

The Rado Captain Cook Open Heart is a Swiss automatic men's dive-style watch for those who want a modern take on a nautical classic. It pairs a round 42 mm case with a green gradient lacquered dial and a yellow gold coloured bracelet.

The case is built from stainless steel with PVD and high-tech ceramic, topped with a sapphire crystal. The automatic movement runs on a power reserve of 80 hours, and water resistance is rated at 30 bar, or 300 m, with a push-button foldover clasp on the bracelet.

What stands out in daily wear is the long power reserve, which lets the watch sit unworn over a weekend and still keep time. At 12.3 mm thick, it has a solid wrist presence, and the glow-in-the-dark and anti-magnetic features add practical value for diving and sport.

Rado's Captain Cook line carries a long dive-watch heritage, and the Open Heart version reworks it for buyers who want mechanical character with a polished, contemporary finish. Here it is a 42 mm round Swiss automatic with a green gradient lacquered dial and a bracelet in yellow gold colour.

The technical story starts with the 80 hour power reserve, well beyond many automatics, so the watch survives a weekend off the wrist. The case combines stainless steel with PVD and high-tech ceramic, and the dial sits under a sapphire crystal that resists scratches in daily wear.

The trade-off is size and weight. At 12.3 mm thick and with a heavy bracelet, it will feel substantial on smaller wrists, and the PVD coating on a daily-worn bracelet can show wear at the edges over the years. The foldover clasp with push-buttons is secure but offers no obvious fine-adjustment detail in the specifications.

It suits someone who wants a genuine 300 m rated automatic that looks dressier than a typical tool diver. If you prioritise pure dive-tool utility at a similar price, a steel-bracelet diver from the Swiss mid-range is worth cross-shopping.
