To celebrate 40 years of tennis partnership, Rado unveils the Captain Cook x Tennis Limited Edition—an homage to the brand’s first major sponsorship at the 1985 Swiss Open in Gstaad. Limited to 1,985 pieces, it reflects a legacy of precision, performance, and enduring ties to the sport. The 39 mm polished stainless steel case is paired with a polished stainless steel turning bezel and a brushed plasma ceramic insert, engraved with numerals, markers, and a triangle filled with white Super-LumiNova®. Topped with a box-shaped sapphire crystal—crystallised at over 2,000°C and coated with anti-reflective layers on both sides—the surface offers exceptional clarity and scratch resistance. The case is water-resistant to 30 bar (300 metres), underscoring its readiness for high-performance wear. At its core beats the Calibre R763, a self-winding movement developed for uncompromising reliability. Engineered with 25 jewels and regulated in five positions, it ensures precise timekeeping under the most demanding conditions. The movement is equipped with an antimagnetic Nivachron™ hairspring. With a robust 80-hour power reserve, the R763 exemplifies technical mastery and mechanical resilience, embodying the spirit of Swiss engineering and Rado’s continued pursuit of horological excellence. The ruthenium to white gradient dial reflects a pure expression of refined aesthetics. The hour and minute hands, along with the rhodium-coloured indexes, are coated with white Super-LumiNova® to ensure optimal legibility in low light. The date guichet at 3 o’clock and the iconic rotating anchor on a ruby backplate underscore the dial’s meticulous attention to detail. A ruthenium-coloured flange encircles the dial, punctuated by yellow Super-LumiNova® dots at 3, 6, 8, and 12 o’clock—subtle markers corresponding to 15, 30, 40, and game point in tennis scoring. The second hand features dark yellow Super-LumiNova®, adding a final layer of visibility and functional elegance. The design is completed by a polished and brushed stainless steel rice-grain bracelet, secured by a stainless steel three-fold clasp for a seamless fit. The watch also includes three additional textile NATO-style straps in blue, green, and orange, each fitted with a stainless steel pin buckle. All straps and the bracelet feature the EasyClip system, allowing for quick and tool-free changes.
