Description
Rado True Round Automatic Open Heart
The Rado True Round Automatic Open Heart brings together contemporary ceramic construction and traditional mechanical watchmaking. Reference R27107172 features a 40mm polished black high-tech ceramic monobloc case and crown, paired with a matching black high-tech ceramic bracelet.
Its open-heart design reveals part of the automatic movement through the dial, creating a distinctive visual connection between the watch’s exterior design and its mechanical mechanism.
Black Sunray Open-Heart Dial
The black sunray dial gives the watch a refined monochromatic appearance. Rose-gold-colored bevels add contrast, while the grey printed minute track provides additional definition.
Super-LumiNova® details are applied to the indexes and hands for enhanced readability in lower-light conditions.
Rado Calibre R734 Automatic Movement
Powering the watch is Rado Calibre R734, an automatic mechanical movement with an approximately 80-hour power reserve.
The movement incorporates an antimagnetic Nivachron™ hairspring and is tested in five positions for accuracy.
Black High-Tech Ceramic Construction
The case and bracelet use polished black high-tech ceramic, giving the True Round Open Heart a smooth and contemporary appearance.
The case measures 40mm in diameter and 10.4mm in thickness, while the transparent sapphire caseback incorporates black PVD-coated titanium and allows the movement to be viewed from the rear.
Sapphire Crystal and Display Caseback
The watch uses sapphire crystal for durability and a transparent sapphire caseback that provides a view of the R734 automatic movement.
The combination of ceramic, sapphire and titanium creates a modern technical character while maintaining the minimalist appearance of the True Round collection.
