Stepping up in Rado's range
At 42mm and 12.3mm thick, the Captain Cook sits with solid presence on the wrist. The lacquered dial shifts from green to black in a sunburst gradient, with rose-gold-coloured hands and applied indices both carrying white Super-LumiNova. The ridged bezel incorporates a green ceramic insert with yellow gold PVD plating, and the box-shaped sapphire crystal curves upward with an anti-reflective coating underneath. The three-link bracelet pairs polished stainless steel outer links with yellow gold PVD middle links, secured by a folding clasp. A screw-down crown and case back support 300 metres of water resistance. Inside, the R763 automatic movement runs an 80-hour power reserve and uses a Nivachron hairspring for antimagnetic protection.

Learn more about Rado
Rado began as Schlup & Co, a movement manufacturer founded by the Schlup brothers in Lengnau in 1917. It became one of the largest movement producers in the world before releasing watches under the Rado name in 1957.
The brand's entire identity rests on a single question: how do you stop a watch from looking worn? The DiaStar of 1962 was marketed as the world's first scratchproof watch, using hardmetal — tungsten carbide — and a sapphire crystal at a time when both were exotic in watchmaking.
Rado then spent decades pushing further into materials most watchmakers avoided because they are difficult to machine and impossible to correct. High-tech ceramic arrived in 1986 with the Integral, and the Ceramica of 1990 was made almost entirely from it. The company developed plasma high-tech ceramic, which is heated to 20,000 degrees to acquire a metallic sheen without any metal content, and Ceramos, a ceramic-metal composite.
The V10K of 2002 used high-tech diamond and reached 10,000 on the Vickers scale — the hardness of diamond itself, and a Guinness record.
Rado's design language is correspondingly clean and monolithic, with the True and Captain Cook lines carrying the modern collection. The company has been part of the Swatch Group since 1983.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 300m it is rated for swimming, snorkelling and recreational diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 80 hours fully wound — enough to sit off the wrist over a weekend and still be running.
Is it a men's or women's watch?
Listed as men's.
