Waterproof Smart Watch with Bluetooth Calls DEVIA Smart Watch WT3 (Blue)

Description

The DEVIA Smart Watch WT3 (factory reference Z123) in its blue version is a top-choice technological piece of equipment for resellers and phone shops. Designed to offer an excellent compromise between premium features and price accessibility, this smartwatch targets active users looking for a versatile daily assistant. Its modern design, highlighted by a blue sports silicone strap and a sleek metallic dial, makes it a high-turnover product in B2B displays.

In terms of embedded features, the DEVIA WT3 stands out for its native management of phone calls via a stable bidirectional Bluetooth link. Thanks to the integration of a high-sensitivity microphone with echo reduction and a waterproof micro-speaker, the user can dial numbers or answer callers directly from their wrist without taking out their smartphone. Physical performance analysis is provided by a triaxial accelerometer and a photoplethysmography (PPG) sensor placed in contact with the skin, allowing real-time monitoring of heart rate, blood oxygen level (SpO2), and sleep cycles.

The watch case is machined from a lightweight and resistant zinc alloy, complemented by a 2.5D tempered glass lens that protects the touch screen from daily micro-shocks. IP67 certified, the internal structure benefits from a hermetic assembly protecting it against the intrusion of fine dust and the effects of temporary immersion. The fluid software interface offers multiple internal sports modes, notification synchronisation (SMS, messaging apps) as well as optimised energy management ensuring several days of continuous battery life.

Workshop Advice & Usage

During the sale or initial configuration for the end customer, remind them that the IP67 waterproof rating excludes exposing the watch to pressurised water or hot fluids. Use in the shower or in a bath is a frequent cause of premature oxidation not covered by after-sales service, as water vapour can infiltrate through the speaker membrane. For pairing, ensure you connect the watch first via the dedicated app for health data synchronisation, then secondly in the smartphone's Bluetooth settings to activate the "Audio/Calls" function of the watch.
