Rado True Round Automatic Open Heart

The Rado True Round Automatic Open Heart brings together contemporary materials and traditional mechanical watchmaking in a refined round design. Its open-heart dial provides a view of the mechanical movement, creating a distinctive focal point while maintaining the clean character of the True Round collection.

The 40mm case is based on Rado’s plasma high-tech ceramic construction, a material associated with the brand’s modern watchmaking approach. The case measures approximately 10.4mm thick, giving the watch a relatively streamlined profile. Rado’s verified True Round Open Heart platform uses a transparent sapphire caseback with a titanium structure.

Brown Open-Heart Dial

The brown dial gives this configuration a warm and sophisticated appearance. The open-heart aperture adds mechanical character by exposing part of the movement, while contrasting details provide visual definition across the dial.

Note: Rado’s official R27108112 documentation identifies its dial as grey sunray, so the brown dial should only be published as the color shown on your actual product rather than as an official Rado factory specification.

Rado R734 Automatic Movement

The verified True Round Automatic Open Heart platform is powered by Rado Calibre R734, an automatic mechanical movement with an approximately 80-hour power reserve. It uses an antimagnetic Nivachron™ hairspring and is tested in five positions for accuracy.

Plasma High-Tech Ceramic Construction

The plasma high-tech ceramic construction gives the watch a contemporary appearance while keeping the design smooth and minimalist. On the verified R27108112 configuration, Rado uses plasma high-tech ceramic for the monobloc case and bracelet, with a titanium three-fold clasp.

Transparent Sapphire Caseback

The transparent sapphire caseback allows the wearer to observe the mechanical movement from the rear. The caseback incorporates titanium and sapphire crystal as part of Rado’s technical construction.
