Stepping up in Rado's range

Price range £735 to £5,150 across 55 Rado watches in stock.

A compact 30mm case in yellow gold-coloured PVD-coated stainless steel gives this DiaStar a consistent warm tone throughout. The bezel is formed from Ceramos, a high-tech ceramic composite that combines scratch resistance with a polished metallic lustre. Above the yellow, dual-direction brushed dial sits a vertically faceted sapphire crystal with an internal anti-reflective coating, its facets catching light at varying angles. Gold-coloured hands carry white Super-LumiNova details, and the date appears at six o'clock with no numeral markers elsewhere on the dial. The Calibre R586 automatic movement runs on a Nivachron hairspring for antimagnetic protection, offers a 48-hour power reserve, and has been regulated across five positions. The bracelet pairs polished outer links with brushed centre links, all PVD-coated to match the case, and fastens with a three-fold butterfly clasp.

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.

Your new watch

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 explained

Will the glass scratch?

Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.

Sapphire, mineral and acrylic compared

Does 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 compared

How 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.

Is it a men's or women's watch?

Listed as unisex, and at this size it suits any wrist that takes the dimensions.
