Stepping up in the same dial colour
The Integral began in 1986 as the watch that introduced high-tech ceramic to the industry, and this reference keeps faith with that original: the same rectangular case, the same edge-to-edge bracelet integration, the same insistence that nothing interrupts the line from wrist to dial. Nearly four decades on, the material itself remains the point — black ceramic that will not scratch and will not dull, banded with yellow gold-toned PVD steel in a combination that reads closer to jewellery than to sport. At 31mm wide and 7.5mm thick, the proportions are deliberate. The rectangular case sits flush and flat, and at that profile it disappears under a shirt cuff without lifting the fabric. Four diamonds mark the cardinal points on the black dial — restrained enough that they register as structure rather than ornament. The titanium deployment clasp closes with a push-button release and sits light against the skin, the bracelet flowing into the case without a visible join.

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?
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?
No. It is hand-wound, so it needs winding every day or two but never a battery.
Quartz, automatic and solar comparedWill it fit my wrist?
Lug-to-lug is 41.1mm, 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 men's.
