Rado Watch Centrix Diamonds Unisex R30021712. The classic Centrix Quartz Diamonds watch has been reworked not only technically, but also aesthetically. The modified model has a rounded sapphire crystal that extends all the way to the edge, as well as a curved case blending with the curved crystal edge. The adjusted case lugs and the bracelet made of polished stainless steel with black high-tech ceramic middle links complete the overall appearance of this iconic timepiece. The black lacquered dial with 4 diamonds, emphasised with the printed “jubilé” logo, matches perfectly with the rhodium-coloured hands. Thanks to the PreciDrive and HeavyDrive features in the calibre R073 quartz movement, the watch has greater accuracy and resistance to shocks. The watch is water-resistant down to 50 m.
