Wear a smartwatch
with your Rado Captain Cook
Smartlet is compatible with the Rado Captain Cook. Lug width: 18mm / 19mm / 20mm / 21mm / 22mm - natively supported with no adapter. Installation uses the standard spring-bar system. No modification to the watch required. Fully reversible in seconds.
The Captain Cook was introduced in 1962 as a professional dive watch. Rado revived it in 2017, and the revival landed harder than most revivals do - because the original design required almost nothing. Round case, bezel with diving scale, applied indices, hands with lume. The contemporary versions bring that language into high-tech ceramic, bronze, and titanium. The result is one of the most versatile dive watch catalogues at any price point. Smartlet works across the full range.References
