For nearly three decades high-tech ceramic has played a central role in Rado’s approach to watchmaking. High-tech ceramic timepieces are objects of art and craftsmanship: Their smooth stylish surfaces can be metallic or matte, crafted in an ever-expanding array of colours.. They are also a gentle approach to glamour: Lightweight and hypoallergenic, high-tech ceramic watches are incredibly comfortable and can be worn by anyone with sensitive skin.
