KOSPET Tank M4 Silver AMOLED Bluetooth Calling Smart Watch (1.96-inch)

The KOSPET Tank M4 Silver is a feature-rich smartwatch built for everyday durability, clear wrist interaction, and hands-free communication. With a 1.96-inch AMOLED display and Always On Display support, you can check time, notifications, and health metrics quickly—even when you’re outdoors. The watch is designed for both male and female users, making it a practical choice for daily commuting, office use, and active lifestyles where you want quick access to key information without constantly reaching for your phone.

Vivid AMOLED display with Always On convenience

Featuring an AMOLED panel with a 410 x 502 resolution and up to 1000 nits brightness, the Tank M4 Silver delivers sharp visuals and strong readability in bright sunlight. The display is protected by Corning Gorilla Glass 3, helping resist everyday scratches and wear. Always On Display means you don’t have to raise your wrist every time to glance at the screen—ideal for morning routines, meetings, and quick status checks throughout the day.

Bluetooth calling for real wrist communication

This smartwatch supports in-watch voice calling with Bluetooth connectivity (Bluetooth 5.3). You can receive and dial calls directly from your wrist using the built-in microphone and loudspeaker, giving you a more convenient, hands-free way to stay connected while walking, traveling, or working. It also supports real-time notifications for calls, messages, and apps, so you can respond faster—especially useful when you’re in a situation where pulling out your phone is inconvenient.

Health tracking that supports daily wellness

The Tank M4 Silver includes heart rate monitoring and blood oxygen (SpO₂) measurement, helping you keep an eye on key wellness indicators. It also supports stress level and mood tracking, along with sleep stages (including REM), naps, and sleep schedule insights. For users who want a more structured view of recovery and daily routine, these features make it easier to understand patterns over time—compared to basic step-only trackers that don’t provide deeper physiological context.

GPS and multi-sensor support for training and navigation

For outdoor activities and route-based workouts, the watch includes GPS positioning with multi-constellation support (GPS, Galileo, GLONASS, BeiDou, QZSS, NavIC/IRNSS). It also includes a range of sensors such as a VC9213-4PD sensor, 6-axis gyroscope, geomagnetic sensor, ambient light sensor, and temperature sensor. With features like route records, route deviation reminders, route back, offline maps, and real-time navigation, it’s well-suited for walking, running, and exploring new areas—especially when you want guidance without relying solely on your phone’s screen.

Sports modes and training tools for active users

The Tank M4 supports ApexMotion Sports with 23 modes and Freestyle Training Modes with 160 options, helping you choose training profiles that match your routine. It also offers heart rate zones, SWOLF, lap count, stroke recognition, and other activity metrics such as average pace, cadence, and step rate. If you’re comparing this to simpler fitness bands, the added training depth and navigation features make it a stronger option for users who want both performance insights and route guidance in one device.

Rugged build with IP69K water resistance

Built with a stainless steel body and liquid silicone strap, the Tank M4 Silver is designed to handle daily wear. It is waterproof with an IP69K rating, along with dustproof and shockproof support, making it suitable for outdoor activities and everyday exposure. This level of protection is especially helpful for users who sweat during workouts, commute in unpredictable weather, or want a smartwatch that can keep up with an active routine.

Battery and charging for day-to-day reliability

The watch uses a 500mAh battery and supports magnetic charging. The theoretical charging duration is approximately 2 hours, and the system supports 24H health monitoring features such as heart rate, blood oxygen, stress level, and mood. For practical use, this means you can track key metrics throughout the day while still maintaining a manageable charging routine—ideal for people who want consistent monitoring without frequent top-ups.

Compatibility and app ecosystem

The Tank M4 is compatible with Android 7.0 and above, and iOS 14.0 and above. It syncs with Apple Health and Strava, and it supports Apexmove for data synchronization. This makes it easier to integrate smartwatch insights into your existing fitness workflow, whether you prefer tracking in Apple Health or using Strava for training logs and performance trends.

Warranty support

The KOSPET Tank M4 Silver comes with a 1 Year warranty. Warranty claims must be made with the original box and all accessories, helping ensure proper service eligibility.
