Wear a smartwatch with your Omega Seamaster 300M | Smartlet

Yes. The Omega Seamaster 300M uses a 19mm / 20mm / 21mm lug width and is fully compatible with Smartlet. Smartlet replaces the standard strap via the spring-bar system and positions your smartwatch on the same wrist. The Omega Seamaster 300M requires no modification, no drilling, and no adhesive. The setup is fully reversible in seconds and your Omega can be worn independently at any time by reinstalling its original strap.

No. Smartlet makes no contact with the Omega Seamaster 300M case, bezel, or crystal. It replaces the strap only, using the existing spring-bar slots. The module is manufactured in 316L stainless steel or titanium with polished and brushed finishing, and all contact points are non-abrasive. Your Omega Seamaster 300M is protected throughout. The system is fully reversible and leaves no trace.

Smartlet is compatible with Apple Watch (all series), Samsung Galaxy Watch (4, 5, 6, 7), Garmin Fenix (6, 7, 8), Garmin Forerunner, Garmin Venu, Google Pixel Watch, Polar Vantage, Fitbit Charge, Huawei Watch GT, Withings ScanWatch, Coros, Suunto, and Whoop. The Omega Seamaster 300M with its 19mm / 20mm / 21mm lug width is compatible with the full Smartlet range. All smartwatch sensors remain operational when worn via Smartlet.
