Wear a smartwatch
with your Rado

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.

How it works

Three steps to both watches on one wrist

Choose your strap

Smartlet One is your new strap. It replaces the original bracelet or strap on your Rolex using the same spring-bar system. Lug widths 20mm / 21mm are all natively supported.

Clip in your watch

Attach the Smartlet strap to your Rolex by fitting the spring bars into the lugs, exactly as with any standard strap change. No tools required. Fully reversible in seconds.

Clip in your smartwatch

Slide your smartwatch into the Smartlet module. It locks onto the strap module on the wrist side of your wrist. All sensors remain fully operational. Both watches run simultaneously.
