Oiviato S81 Smart Watch for Daily Health

The Oiviato S81 is a new smart watch with a 1.39 inch touch screen and a black silicone band. It targets adults who want continuous heart rate, blood oxygen (SpO2) and sleep analysis alongside 120 plus sport modes. IP68 water resistance lets it handle hand washing, swimming and surfing. Bluetooth connectivity pairs with Android and iOS smartphones for call handling and app notifications.

Pairing and Setup Experience

Pairing uses standard Bluetooth; the watch appears in the phone settings and a companion app completes the link. Most users finish pairing in a few minutes. Common issues include forgetting to grant notification access for specific apps, which silences Facebook, Instagram, WhatsApp or Twitter alerts. The microphone and Hi-Fi speaker handle calls directly on the wrist, but call clarity depends on phone signal strength and ambient noise.

Compatibility Check Before Ordering

Verify that your smartphone runs a recent Android or iOS version and supports Bluetooth. The watch requires the companion app for health data sync and firmware updates, so confirm the app is available in your region's store. No cellular radio is present; the watch must stay in Bluetooth range of the phone for calls and notifications. Buyers who need standalone LTE connectivity or onboard music storage should look elsewhere.

Questions about this item

How can I confirm the 1.39-inch touch screen and sensors are working after pairing the S81?

After pairing, open the companion app to see live heart-rate, SpO2 and step readings; the 1.39-inch display should show real-time data and respond to touch, confirming the optical sensors and screen are active.

What comes in the box with the black S81 and what must I supply myself?

The box includes the S81 smartwatch with its black silicone band and a charging cable; you only need to provide a compatible smartphone running Android or iOS and the free companion app.

Which version of the Oiviato S81 should I choose for the full feature set?

The S81 is offered in a single black 1.39-inch model with IP68 water resistance, 120-plus sport modes, Bluetooth calling and SpO2 monitoring, so no capacity or version choice is required.
