Rado DiaStar Original Open Heart Men’s Automatic 35mm Silver

Rado’s DiaStar Original Open Heart, model R12063103, brings a sharp silver-toned profile in a compact 35 mm case. The black sunray dial is detailed with rhodium-coloured bevels and six cubic zirconia, while the open-heart layout adds visual depth. A vertical faceted sapphire crystal sits over a hardmetal bezel and stainless-steel middle part, keeping the design clean and precise. Inside, the automatic movement offers an 80-hour power reserve and an antimagnetic Nivachron hairspring. Finished with a folded stainless-steel bracelet and clasp with openers, it’s a refined everyday watch with a neat, balanced fit.
