Wear your Garmin Venu
and your mechanical watch
at the same time
Garmin Venu combines a vivid AMOLED display with Garmin's full health platform - Body Battery, SpO2, HRV status, stress tracking, advanced sleep staging, and wellness metrics designed for everyday life. Your Cartier Tank or Jaeger-LeCoultre Reverso requires no such justification. Smartlet One clips your Garmin Venu onto any mechanical watch strap via a 20mm adapter. Venu 2S, 3S, and Sq 2 (40mm) use an 18mm lug width, natively supported by Smartlet. Both watches occupy the same wrist simultaneously.
How it works
Classic, Shadow, or Titanium. Match your mechanical watch case material and aesthetic. No tools required at this stage.
Attach the Smartlet adapter to your watch lugs. The spring-loaded mechanism locks in place with zero metal-to-metal case contact. Fully reversible in seconds.
Attach the Smartlet adapter to your Garmin Venu. It locks securely. Both watches sit on the same wrist. All sensors remain in contact with your skin.

Frequently asked
Can I wear a Garmin Venu and a mechanical watch at the same time?
Yes. Smartlet One is a modular adapter that clips onto any mechanical watch via an 18mm to 24mm adapter, allowing you to simultaneously wear your Garmin Venu on the same wrist. Both watches operate independently. No modification required.
Which Garmin Venu models are compatible with Smartlet?
Garmin Venu 2, 2 Plus, 3, and Venu Sq 2 are all compatible with Smartlet. The standard Venu 2, 2 Plus, and 3 use 20mm or 22mm lugs and are natively supported. The S variants (Venu 2S, 3S) and Venu Sq 2 (all 40mm) use 18mm lugs, which are natively supported by Smartlet. No adapter required.
Will Garmin Venu sensors still work when attached to Smartlet?
Yes. All Garmin Venu sensors including SpO2, optical heart rate, HRV, and stress tracking maintain full wrist contact via Smartlet. Body Battery calculations and sleep staging accuracy are unaffected.
Does Smartlet work with Garmin Venu 3?
Yes. The Garmin Venu 3 (45mm) uses a 22mm lug width and is fully compatible with Smartlet. The Venu 3S (40mm) uses 18mm lugs, which are natively supported. No adapter required.
