The Rado True Round Automatic Open Heart White Dial is a contemporary mechanical timepiece that combines Rado’s distinctive high-tech ceramic construction with an elegant open-heart dial design.

The official Rado R27115012 features a 40mm polished white high-tech ceramic monobloc case and crown, creating a clean monochromatic appearance. The case measures 10.4mm in thickness, giving the watch a refined profile while retaining the distinctive presence of the True Round collection.

The white sunray dial is enhanced by rose-gold-colored bevels and a grey printed minute track. Super-LumiNova® details on the hands and indexes provide additional readability in lower-light conditions. The open-heart aperture offers a view of the mechanical movement beneath the dial.

Powering the watch is Rado Calibre R734, an automatic mechanical movement equipped with an antimagnetic Nivachron™ hairspring. Rado specifies an 80-hour power reserve, and the movement is tested in five positions for accuracy.

The transparent sapphire caseback is mounted over a titanium caseback, allowing the mechanical movement to remain visible from the rear. The watch is completed with a polished white high-tech ceramic bracelet and a titanium three-fold clasp.

With 50m water resistance, the Rado True Round Automatic Open Heart offers practical protection for everyday wear while maintaining its sophisticated mechanical-watch character.
