Smartlet One
One concept. Three different personalities
Rolex Datejust and Apple Watch on the same wrist
Compatibility guide
Rolex Datejust & Apple Watch on the same wrist
Yes. The Rolex Datejust 36 uses a 20mm lug width and the Datejust 41 uses a 21mm lug width, both natively supported by Smartlet One. Apple Watch mounts on the inner wrist via the Smartlet module. The Datejust's jubilee or oyster bracelet can be reinstalled at any time.
Context
Why Rolex Datejust owners wear Apple Watch too
The boardroom watch and daily functionality
The Rolex Datejust has been in continuous production since 1945. Worn in boardrooms, at formal events, and as an everyday companion.
The Apple Watch adds health monitoring and notifications without disrupting the Datejust's place on the wrist. Smartlet Classic's polished SS316L finish pairs naturally with the Datejust's aesthetic. The combination works precisely because neither device announces itself.

Questions
Common questions about wearing a Rolex Datejust and Apple Watch together
Does Smartlet work with the Datejust on a jubilee bracelet?
Smartlet replaces the strap or bracelet entirely using the same spring-bar slots. Whether your Datejust came on an Oyster or jubilee bracelet, installation is identical. Your original bracelet can be reinstalled at any time.
Which Datejust references are compatible with Smartlet?
Datejust 36 (ref. 126200, 126234, 126233, 20mm) and Datejust 41 (ref. 126300, 126334, 126333, 21mm) are all compatible. Lady-Datejust uses smaller lug widths and is outside Smartlet's current range.
Is the Classic or Shadow finish better for the Datejust?
The Smartlet Classic's polished and brushed SS316L is the most natural pairing with the Datejust's Rolesor or steel cases. The Shadow's PVD black coating offers a more contemporary contrast. Both are compatible and the choice is purely aesthetic.
