Stepping up in the same colour and case shape
The Centrix is Rado's long-running argument for ceramic as a material of substance rather than novelty, and this 28mm variant makes that case in a particularly considered way. The bracelet alternates yellow gold PVD steel with black high-tech ceramic links — two materials that agree on geometry while staying visually distinct — and the integrated titanium butterfly clasp continues that line without interruption. At 6.7mm thin, it disappears against the wrist in the way that only a properly resolved case profile can. The black dial keeps almost nothing on it: gold-tone hands and four diamond indices at the cardinal positions, which gives it a formality the specifications alone would not suggest. The ETA 956.112 earns its place here not through complication but through the end-of-life indicator that moves the seconds hand to four-second jumps when the battery needs attention — a small courtesy that matters more than it sounds when the watch is dressed up and out.

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?
No. At 30m it will survive rain and handwashing, but not submersion of any kind.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
What size strap does it take?
14mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Is it a men's or women's watch?
Listed as women's.
