Korean actor and screen star Ji Chang-wook is a Rado global brand ambassador and co-designer of his own limited-edition True Square Open Heart. The elegant, matt black monobloc high-tech ceramic case holds a flat sapphire crystal glass with anti-reflective coating on both faces, offering illuminating views of the wide-open dial and its hour markers – 12 bright rubies with matching red Super-LumiNova® highlights on the hands.

The sandblasted titanium case back with smoked sapphire crystal presents the words LIMITED EDITION, ONE OUT OF 987, along with the Ji Chang-wook’s signature, all in white. This stunning new model is powered by Rado calibre R734, a 25-jewel, 3-hand automatic that exceeds standard test requirements and features an anti-magnetic Nivachron™ hairspring and a remarkable 80-hour power reserve.
