Durable watch for demanding conditions
The KOSPET TANK M4 smartwatch is designed to handle both daily wear and more demanding outdoor activities. The stainless steel construction features the Inox 360 design, which includes the bezel, case, and physical buttons. The watch's durability has been tested against 20 MIL-STD-810H standards, including tests for high and low temperatures, humidity, shock, vibration, rain, dust, sand, and thermal shock. This makes it ready for training, hiking, travelling, and everyday use in changing environments.
10 ATM water resistance and IP69K rating
The KOSPET TANK M4 offers 10 ATM water resistance and an IP69K rating, making it suitable not only for everyday contact with water but also for swimming, water sports, and diving activities. The watch is designed to withstand water pressure equivalent to a depth of 100 metres and supports dives of up to 45 metres. This means you can use it for swimming, surfing, freediving, and recreational diving. The watch is not intended for hot showers, saunas, or activities involving high temperatures and humidity.
Diving modes for a better underwater overview
The KOSPET TANK M4 watch has three diving modes: Freedive, Scuba Dive, and Gauge. In freediving mode, it tracks metrics such as dive time, maximum depth, surface intervals, and average temperature. Scuba Dive mode lets you work with parameters like oxygen percentage or PO₂ limit, providing an overview of important data for recreational diving. Gauge mode serves as a basic bottom timer or a backup tool for more experienced divers, as it displays dive time and depth.
AMOLED display with auto-brightness
The large 1.96" AMOLED display shows data clearly during sports, everyday use, and outdoors. A resolution of 410×502px, a fineness of 331PPI, and a brightness of up to 1000 nits ensure good readability in various lighting conditions. The integrated ambient light sensor automatically adjusts the display's brightness according to the environment, so the watch is easy to use during the day, in the evening, and when moving quickly between indoors and outdoors.
ApexMotion sports modes
The KOSPET TANK M4 helps track your performance in running, cycling, swimming, skiing, hiking, and other sports. It offers 23 ApexMotion modes and another 160 free training modes, so it easily adapts to regular training and specific outdoor activities. The watch can track metrics like pace, cadence, distance, elevation, heart rate, heart rate zones, SWOLF, number of pools, or average swimming pace.
More accurate motion tracking with a 6-axis gyroscope
The built-in 6-axis gyroscope helps the watch better track movement, changes in direction, posture, and dynamics during training. This lets the KOSPET TANK M4 capture intense workouts, rapid changes in movement, and sports activities with greater precision. The measured data then provides a better overview of your performance and progress during regular training.
Dual-band GPS and 6 satellite systems
The KOSPET TANK M4 uses dual-band L1+L5 GPS and supports six satellite systems—GPS, Galileo, GLONASS, BeiDou, QZSS, and NavIC. This enables it to more accurately track your route during running, hiking, cycling, and other outdoor activities. The OPDR algorithm helps maintain a more accurate activity log even in challenging conditions, such as in urban areas, under bridges, or in places with a weaker GPS signal.
Offline maps and route import
With the KOSPET TANK M4 watch, you can use offline maps, import routes, record your route, return along the same route, and get real-time navigation. You can import GPX or KML files via the Apexmove app, or prepare your own route. Thanks to the 32GB of storage, you can save offline maps to the watch and set off without constantly relying on your phone.
Storage for music and maps
The internal 32GB of storage offers space for both offline maps and music. The watch can hold approximately up to 100 offline maps or up to 5000 songs, making it suitable for sports and travel without needing your phone handy at all times. The actual available capacity may vary depending on system software, file format, and usage.
Walkie-talkie for communication in the field
The built-in walkie-talkie function enables quick communication with other users of compatible watches. When cycling, hiking, or out in nature, a simple press and hold provides an instant connection. The range may vary depending on surrounding conditions, terrain, and obstacles.
Continuous health tracking
The KOSPET TANK M4 is equipped with an advanced 4PD health sensor for continuous monitoring of important metrics. The watch monitors heart rate, blood oxygen SpO₂, stress level, mood, and sleep, including sleep stages and REM. It also offers alerts for unusually high or low heart rates and low blood oxygen levels. One-touch measurement lets you quickly check selected values in one place.
Sleep and recovery overview
The watch helps you monitor your sleep quality, including main sleep stages, REM sleep, and short naps. In the app, you can create a custom sleep plan and get an overview of your sleep duration and patterns in the morning. This gives you better insight into how your resting habits are changing and how sleep relates to your overall recovery.
Long battery life
The 500mAh battery provides up to 14–15 days of life with typical use. With heavier use, the watch lasts for approximately 9–10 days, around 5–6 days in Always-On Display mode, and up to 21–22 hours with continuous GPS use. The magnetic charging dock enables convenient charging, and a full charge takes approximately 2 hours.
Apexmove OS and the Apexmove app
The Apexmove OS provides clear controls, a personalised environment, and a connection to the Apexmove app. In the app, you can track detailed health and fitness data, manage training plans, create routes and points on the map, download offline maps, or sync music directly to the watch. It also supports synchronisation with Apple Health and Strava.
Watch faces and environment customisation
The KOSPET TANK M4 lets you customise the look of the watch face and environment to your preferences. In the Apexmove app, you can choose from a wide range of watch faces, edit widgets, upload your own image, set an AOD watch face, or customise shortcut cards. Several menu styles, icon themes, and transition animations are also available.
Smart features for every day
The watch is equipped with a built-in speaker and microphone, so it supports Bluetooth calling. It alerts you to phone notifications and offers practical outdoor functions like a compass, barometric altimeter, torch, temperature sensor, and information about the weather, moon phase, tides, and sunrise/sunset times. This makes it useful not only for sport but also for everyday use.
