A new version of Rado's True Square Open Heart

Rado’s True Square has attracted a great deal of attention over the last year with its premiere. Its gently rounded corners, scratch-proof high-tech ceramic and smooth feel effortlessly combine apparent opposites. The Open Heart version also grants a sophisticated glimpse into its mechanical heart – which is now also presented with silver-grey accents.


he black dial of Rado’s new True Square Open Heart with an automatic movement has large cut-outs and features rhodium-coloured bevelled edges. The skeletonisation allows the finely decorated Swiss-made movement, which offers a power reserve of 80 hours and is a work of art in itself, to be seen. The hands and indexes are also rhodium coloured and filled with white Super-LumiNova®.

The polished black high-tech ceramic case is equipped with a titanium case back with black PVD coating and sapphire crystal. Its monobloc construction is created using injection moulding, which demands meticulous precision in manufacturing – a technique that we have perfected. This is actually the first square watch with a monobloc case made from high-tech ceramic. This timepiece is completed with a bracelet made from polished black high-tech ceramic.

The True Square Open Heart with an automatic movement combines everything that makes Rado what it is: unmistakable design, innovative materials, a sensual feel, maximum scratch resistance and Swiss precision.
