Waterproof Smart Watch with Bluetooth Calls DEVIA Smart Watch WT5 (Grey)

Description

The DEVIA Smart Watch WT5 (factory reference Z139) in its grey version is a mid-range digital device perfectly calibrated for the catalog of resellers and professionals in the mobile ecosystem. Developed to offer a complete and accessible notification center, this watch targets users looking for a large display and integrated communication functions. Its grey metal alloy case gives it a sober, modern, and technological aesthetic, ensuring strong visual appeal in B2B retail spaces.

At the heart of its specifications, the DEVIA WT5 integrates a Dual-Bluetooth controller capable of separating health data streams from high-bandwidth audio streams. This architecture allows for native management of the wireless calling function: the technician or end-user can thus sync their directory, dial a number via a dedicated touch keypad, or take a call directly from their wrist thanks to the integrated omnidirectional microphone and speaker. Regarding biometric tracking, the WT5 is equipped with an optical photoplethysmography (PPG) sensor that continuously analyzes heart rate, oxygen saturation index (SpO2), and sleep quality.

The outer casing is entirely machined from a high-pressure injected zinc alloy, increasing its structural resistance against micro-shocks and abrasion. The capacitive touchscreen is protected by mineral glass with curved edges, promoting smooth gliding and optimal readability under bright light. IP67 certified, the watch benefits from proven water resistance against the intrusion of fine dust and fresh water splashes, while its hypoallergenic silicone strap ensures lasting comfort during sports sessions or prolonged daily use.

Workshop Advice & Usage

To ensure the longevity of the product and optimize the after-sales satisfaction rate, it is essential to warn the end customer that the IP67 certification formally excludes any immersion in seawater or use under a hot shower. Heat causes micro-expansion of the seals, which allows steam to saturate the microphone's acoustic chamber. During commissioning, guide the customer to perform the first pairing imperatively via the companion app by scanning the QR code in the manual, then the secondary pairing in the smartphone's Bluetooth settings to activate the audio channel dedicated to phone calls.
