Wear a smartwatch with your Rado

In short Smartlet One is compatible with all Rado Captain Cook, DiaStar, and Centrix references using 20mm to 22mm lug widths, natively supported with no adapter. Installation uses the standard spring-bar system - no modification to the watch, fully reversible in seconds.

Rado pioneered hard metal and ceramic in watchmaking at a time when steel was the only serious material on the market. The DiaStar of 1962 used tungsten carbide. The HyperChrome uses plasma high-tech ceramic that resists scratching better than sapphire crystal. Rado collectors value materials science alongside horology. Smartlet One uses SS316L steel and PVD-coated titanium - materials that sit without conflict on the same wrist as ceramic.

Wear yours How it works
The problem
Choosing between health data and horological heritage every morning.
The solution
Smartlet One replaces your Rado's strap via the standard spring-bar system and positions your smartwatch on the same wrist. Both watches run simultaneously, with no modification to the watch and full reversibility in seconds.

Questions

Frequently asked questions

  • Does Smartlet work with Rado watches?
    Yes. Rado references from 18mm to 22mm lug width are natively supported by Smartlet One.
  • Will Smartlet affect the ceramic case?
    No. Smartlet uses the same spring-bar slots used for strap changes. The ultra-hard ceramic is completely untouched.
  • Which Rado models have guides?
    The Captain Cook has a full reference table covering 110 references across 37mm to 43mm case sizes.
  • Beschädigt oder verändert Smartlet meine mechanische Uhr?
    Nein. Smartlet ersetzt Ihr Standard-Uhrenarmband mit dem vorhandenen Federstift-System. Es werden keine dauerhaften Änderungen am Uhrengehäuse, den Hörnchen oder dem Zifferblatt vorgenommen. Der Vorgang ist vollständig reversibel und dauert nur Sekunden. Ihre mechanische Uhr bleibt unbeeinträchtigt und kann jederzeit unabhängig getragen werden, indem Sie einfach das Originalarmband wieder anbringen. Smartlet ist nach Uhrmacher-Toleranzen konstruiert und wird mit der gleichen Sorgfalt getestet, die auch in die Uhren fließt, mit denen es kombiniert wird.
