Rado True Square Automatic Open Heart

R27073702

White was one of the three colours of the True Square Open Heart at its 2020 launch, beside black and plasma grey, and this white reference sets twelve diamonds as hour markers on its dial, 0.096 carat in all. When Harper's Bazaar Malaysia presented the black and white models as a his-and-hers pair, the diamonds were the white watch's distinguishing touch. The case is an injected monobloc of polished white high-tech ceramic, 38 mm across and 9.7 mm thick, and the bracelet is the same white ceramic with a titanium three-fold clasp. Luxuo reported at launch that Rado fitted a titanium caseback to keep the weight down, and the complete watch comes to 120 g. Through the open heart you see the R734 automatic, which has an antimagnetic Nivachron hairspring and 80 hours of reserve, and the hands carry Super-LumiNova. It lists at $3,600.
