Rado HyperChrome Automatic Open Heart R32021102

The Rado HyperChrome Automatic Open Heart R32021102 is a 42mm watch with a case combining Plasma high-tech ceramic and steel, and an open-heart dial revealing the oscillating balance wheel — distinct in material and construction from the steel Captain Cook and the ceramic-monobloc True Square already in the catalog. It runs the automatic R734 caliber with 80 hours of power reserve. We have no verified price observations for this reference as of today (n=0).

History

Rado was founded in 1917 in Lengnau, Switzerland, and built its brand identity around materials research, with milestones like the 1962 DiaStar and, more recently, the monobloc high-tech ceramic of the True line.

The HyperChrome family is the most eclectic branch of Rado's catalog in terms of finishes and complications, mixing advanced materials — here, matte-grey Plasma ceramic — with steel and PVD components in the same case, unlike the True Square's monobloc construction with no metal core.

The R32021102 adds an open-heart complication to that base: a dial-side cutout at 6 o'clock exposing the oscillating balance wheel, with the automatic R734 caliber (based on the antimagnetic-hairspring ETA C07.611 with Nivachron) delivering 80 hours of power reserve.

This is Rado's third reference in Cazador's catalog. Alongside the Captain Cook (steel, vintage dive) and the True Square (monobloc ceramic, no metal core), the HyperChrome Open Heart illustrates a third path for the brand: mixed materials with a focus on displaying the movement itself.

Frequently asked questions

How much does a Rado HyperChrome Automatic Open Heart R32021102 cost?

Cazador has no verified price observations for this reference (0 PricePoints recorded as of today). We do not publish estimates without our own sourced market data.

What is the 'open heart' complication?

It's a cutout in the dial, usually near 6 o'clock, that reveals the movement's balance wheel oscillating in real time.

How does it differ from the Rado True Square, the brand's other ceramic piece in Cazador?

The True Square uses monobloc ceramic construction with no internal metal core; the HyperChrome combines Plasma ceramic with steel and PVD components in the same case.

What is the Nivachron hairspring in the R734 caliber?

It's a titanium-based alloy developed by Swatch Group that reduces the movement's sensitivity to magnetic fields and temperature swings compared to traditional steel.

Is it suitable for swimming or diving?

Its 5 bar (50 m) water resistance allows splashes and occasional swimming, but it is not a certified dive watch.

Since when has Rado existed?

Since 1917, founded in Lengnau, Switzerland; the brand centers its identity on researching wear-resistant materials.
