Design & Craftsmanship
The Art of Open-Heart Transparency
The True Square Open Heart transforms traditional mechanical watchmaking into a wearable art form. The sculpted dial cutaways allow light to pass through the movement, showcasing the rapid oscillation of the balance wheel and the fine perlage decorations beneath polished hands and hour markers.
Master of Materials High-Tech Ceramic
Crafted entirely from Rado’s signature high-tech ceramic, the polished black surface is significantly harder than traditional stainless steel or gold. Ceramic adapts instantly to skin temperature, offering hypoallergenic wear, lightweight comfort, and permanent protection against scratches and fading.
Swiss Calibre R734 with Nivachron™
Inside beats the Swiss-made automatic Calibre R734. Equipped with a titanium-based Nivachron™ balance spring, the movement resists magnetic fields emitted by smartphones, laptops, and everyday electronic devices, ensuring reliable precision across an 80-hour autonomous power reserve.
