Stepping up in Rado's range
A compact 30 mm case in stainless steel, 11 mm thick with a lug-to-lug span of 35.6 mm, giving it a neat, close fit on the wrist. The polished platinum-coloured Ceramos bezel sits above the steel middle case, while a faceted sapphire crystal covers the yellow dial beneath. That dial is brushed in two directions, shifting with the light, and carries a moving gold-coloured anchor alongside a date window at six o'clock. Rhodium-coloured hands are treated with Super-LumiNova. The two-tone bracelet pairs silver and yellow gold PVD-coated steel, fastening with a three-fold deployant clasp. Inside runs the automatic Calibre R586, with a Nivachron hairspring for antimagnetic resistance and a 48-hour power reserve.

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 100m it is rated for swimming and snorkelling, though not for 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 48 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
Will it fit my wrist?
Lug-to-lug is 35.6mm, which suits wrists from roughly 15cm (6 inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as unisex, and at this size it suits any wrist that takes the dimensions.
