Vivo iQOO Watch GT

Manufacturer: Vivo

The Vivo iQOO Watch GT is a smartwatch designed for active daily use, offering a 1.85″ OLED touchscreen with Always-On Display support and a 322 ppi pixel density, housed in a compact 45.8 x 39.6 mm case that weighs just 33 g with an 11.2 mm profile. The band is replaceable at 22 mm width, the watch is water resistant, and it is compatible with both Android and iOS devices. It is not designed specifically for kids, and the display uses neither sapphire glass nor branded damage-resistant glass.

On the connectivity side, the iQOO Watch GT includes an eSIM slot with cellular support, Bluetooth 5.3, NFC, and Galileo satellite navigation, though Wi-Fi and ANT+ are absent. Health tracking covers heart rate, blood oxygen levels, resting heart rate, and a full suite of activity metrics including steps, distance, pace, elevation, calories burned, and sleep with detailed reports. The 505 mAh battery is rated for up to 21 days and is rechargeable but not removable or solar-powered, and wireless charging is not supported. The watch also supports call answering and control via a built-in microphone, wrist notifications, a stopwatch, silent and vibrating alerts, inactivity alerts, goal setting, coaching, and a camera remote shutter function.

Pros
  • Built-in eSIM with a cellular module allows the watch to make and receive calls independently without relying on a paired phone
  • A 505 mAh battery rated for up to 21 days provides extended use between charges, reducing daily charging dependency
  • The sensor suite covers heart rate, blood oxygen, GPS, accelerometer, gyroscope, and compass, giving a solid foundation for fitness and navigation tracking
  • Comprehensive women's health features in the app include period notifications, fertile window tracking, ovulation prediction, and start date prediction
  • Activity tracking spans steps, distance, pace, elevation, sleep with reports, automatic activity detection, route tracking, exercise tagging, calorie intake, and food tracking
  • NFC and Galileo satellite support broaden payment and location tracking capabilities beyond basic Bluetooth connectivity
Cons
  • Multi-sport mode is not available, limiting structured workout variety for users who regularly switch between different sports
  • No ECG technology or irregular heart rate warnings are present, which reduces the watch's utility for users with cardiac health monitoring needs
  • Wireless charging is not supported, requiring a wired connection each time the battery needs replenishing
  • The companion app is not ad-free, meaning users will encounter advertisements within a health and fitness tracking application
  • Auto pause during workouts is absent, requiring manual intervention when stopping mid-activity
  • No passcode protection is available, leaving the device and its data without a basic security lock
Who is this for?

The Vivo iQOO Watch GT is well matched to users who want a smartwatch capable of operating independently from a smartphone, thanks to its built-in eSIM with cellular support for calls and connectivity on the go. Those who prioritize long battery life for extended trips or busy schedules will benefit from the 21-day rated battery, reducing the need for frequent charging. The watch also suits health-conscious users and everyday fitness trackers who want comprehensive monitoring across sleep, activity, heart rate, blood oxygen, and GPS-based route tracking, as well as women who want menstrual cycle and fertility tracking built into their daily wearable routine.

Who is this NOT for?

Users who engage in diverse structured sports training will find the absence of multi-sport mode limiting, as the watch does not offer dedicated profiles for switching between different athletic disciplines. Those with cardiac health concerns requiring more advanced monitoring will be underserved, since ECG technology and irregular heart rate warnings are both absent. The watch is also a poor fit for security-conscious users, as it offers no passcode protection, and for athletes who expect auto pause during workouts, the lack of that feature requires manual interruption management during interval training or rest stops.

Final Verdict

The Vivo iQOO Watch GT positions itself as a capable everyday smartwatch with a meaningful focus on independent connectivity and endurance, headlined by its built-in eSIM with cellular support and a 21-day battery rating that together reduce reliance on a paired smartphone. Its health and activity tracking suite is broad enough for general fitness users, and the inclusion of women's health features adds practical value for a wider audience. Some gaps — notably the absence of multi-sport mode, ECG, auto pause, and passcode protection — mean it falls short for more specialized athletes or security-minded users. That said, for users who want a lightweight, long-lasting smartwatch with independent calling capability and comprehensive daily health monitoring, the Vivo iQOO Watch GT delivers a well-rounded and functional package within its intended scope.
