Compatibility guide

Yes. The Rolex Submariner is compatible with Smartlet One, which includes a dedicated Whoop 5.0 adapter. The Submariner mounts on the outer wrist via its 20mm or 21mm lug width. Whoop clips into the Smartlet module on the inner wrist with full skin contact. Continuous HRV, sleep, and strain tracking remain fully operational.
Context
Why serious athletes wear a Rolex Submariner and Whoop together
Performance data without removing the Submariner
Whoop's appeal is its discretion, a screenless device focused entirely on recovery, HRV, and sleep quality. The Rolex Submariner is the watch they choose for everything else.
Smartlet solves the daily frustration of switching between the two by making both permanent fixtures on the same wrist. Whoop's inner wrist sensor placement via Smartlet maintains the continuous skin contact required for accurate HRV and sleep tracking. No gaps, no repositioning during the night.
