Stepping up in the same dial colour
The Integral has been Rado's signature square dress watch for decades, its geometry softened just enough to sit comfortably without losing its architectural intent. This version leans into contrast: the gold PVD case and polished yellow gold hands against a lacquered black dial, with four diamonds standing in for the hour markers at the cardinal points. It is a restrained use of stone — 0.040 carats across all four — chosen to catch light rather than announce themselves. At 31.5mm with a square footprint, it wears closer to the wrist than a round case of equivalent width would, and the curved sapphire follows that geometry precisely, the glass doming to meet the wrist rather than sitting flat above it. The bracelet alternates steel outer links with black high-tech ceramic centres, which keeps the two-tone palette running from dial to clasp without a break — and ceramic wears against the skin in a way polished metal simply does not, smoother and cooler through the day.

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?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
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?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Quartz, automatic and solar comparedIs it a men's or women's watch?
Listed as women's.
Cheapest place to buy
