Durable watch for demanding conditions
The KOSPET TANK M4 Special Edition smartwatch is engineered to handle both everyday wear and more demanding outdoor activities. The stainless steel construction uses the Inox 360 solution, which includes the bezel, case, and physical buttons. The watch's durability has been tested according to 20 MIL-STD-810H standards, including tests for high and low temperatures, humidity, shocks, vibrations, rain, dust, sand, and thermal shock. This makes it ready for training, hiking, travelling, and general use in changing environments.
Premium style with steel craftsmanship
The KOSPET TANK M4 Special Edition combines the durability of a sports watch with a more elegant look for everyday wear. The stainless steel gives the watch strength, resilience, and a timeless appearance that is suitable not only for training, but also for work or a day in the city. Thanks to the interchangeable 22mm straps, you can easily adapt the watch to your current activity, outfit, and usage.
10 ATM water resistance and IP69K rating
KOSPET TANK M4 Special Edition offers 10 ATM water resistance and an IP69K rating, making it suitable not only for daily 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 overview underwater
KOSPET TANK M4 Special Edition features three diving modes – Freedive, Scuba Dive, and Gauge. During freediving, it tracks metrics such as dive duration, maximum depth, speed, surface intervals, and average temperature. The Scuba Dive mode allows you to work with data important for recreational diving, including an overview of dive time and safety intervals. The 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 automatic brightness
The large 1.96" AMOLED display shows data clearly during sports, daily use, and outdoors. A resolution of 410 × 502 px, a pixel density of 331 PPI, and a brightness of up to 1000 nits ensure good readability in various lighting conditions. An 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
KOSPET TANK M4 Special Edition helps you 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 gain, heart rate, heart rate zones, SWOLF, pool laps, 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 allows KOSPET TANK M4 Special Edition to capture intense exercise, rapid changes in movement, and sports activities with greater accuracy. The measured data then provides a better overview of your performance and progress during regular training.
Dual-band GPS and 6 satellite systems
KOSPET TANK M4 Special Edition 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 stable activity log even in challenging conditions, such as in built-up urban areas, under bridges, or in places with a weak GPS signal.
Offline maps and route import
With KOSPET TANK M4 Special Edition, you can use offline maps, route import, route recording, return-to-start, and real-time navigation. Through the Apexmove app, you can import GPX or KML files, or prepare your own route. Offline maps need to be downloaded in advance via the app, and their availability depends on the size and detail of the map data.
Storage for offline maps and data
KOSPET TANK M4 Special Edition features 512MB of ROM storage, which is used for the system, offline maps, and selected data. This allows the watch to use map data and navigation even in places without a network connection. The actual available capacity may vary depending on the system software, stored maps, files, and usage.
Walkie-talkie for communication in the field or office
The built-in Walkie-talkie function enables quick, short-range communication with other users of compatible watches. This makes it easier to coordinate a group during work, cycling, hiking, or outdoor activities without needing to take out your phone. The range may vary depending on surrounding conditions, terrain, and obstacles.
Continuous health monitoring
KOSPET TANK M4 Special Edition is equipped with an advanced 4PD health sensor that enables continuous monitoring of important indicators. The watch monitors heart rate, blood oxygen SpO₂, stress levels, mood, and sleep, including sleep stages and REM. It also offers alerts for unusually high or low heart rates and low blood oxygen levels. A one-touch measurement feature lets you quickly check selected values in one place.
Overview of sleep and recovery
The watch helps you monitor sleep quality, including major sleep stages, REM sleep, and short naps. In the app, you can create your own sleep plan and get an overview of your sleep duration and patterns in the morning. This gives you a better insight into how your rest habits are changing and how sleep relates to your overall recovery.
Long battery life
The 500mAh battery provides up to 14–15 days of battery life with typical usage. With heavier usage, the watch lasts approximately 9–10 days, with the Always-On display mode approximately 5–6 days, and with continuous GPS use up to 21–22 hours. 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. Syncing with Apple Health and Strava is also supported.
Watch faces and environment customisation
KOSPET TANK M4 Special Edition allows you to adjust the appearance 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 picture, 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 Bluetooth 5.3, a built-in speaker and microphone. It alerts you to calls, texts, and app notifications, and for Android phones, it also supports quick call replies. It also offers practical outdoor features such as a compass, barometric altimeter, temperature sensor, weather information, moon phase, tide, and sunrise/sunset times. This makes it useful not only for sports but also for everyday use.
Reminders for a better daily routine
Via the Apexmove app, KOSPET TANK M4 Special Edition can display reminders for hydration, medication, and long periods of sitting. The watch helps you maintain a more regular daily routine, even during a busy workday or while travelling. You can use these reminders as simple support for a more active and organised daily routine.
