Durable watch for work and outdoor activities
The KOSPET TANK T4C smartwatch is ready for demanding daily use, fieldwork and outdoor activities. The stainless steel bezel, complemented by a zinc alloy body, creates a robust design that is perfect for environments with dust, rain, moisture and frequent movement. This makes the watch ideal for sports, travel, outdoor work and everyday wear.
AMOLED display with high brightness
The large 1.5" AMOLED display offers a sharp and clear view of your data during sports, work and daily use. A resolution of 466×466px, a pixel density of 438 PPI, a 60Hz refresh rate and a brightness of up to 1000 nits help maintain excellent readability in various lighting conditions. The integrated ambient light sensor automatically adjusts the display brightness to suit your environment.
5 ATM and IP69K water resistance
The KOSPET TANK T4C has 5 ATM water resistance and an IP69K rating, so it can handle rain, splashing water, dust and swimming in a pool. The watch is suitable for everyday wear, outdoor activities and work environments where it might come into contact with water or dirt. It is not designed for hot showers, saunas or environments with high temperatures and humidity. With 5 ATM water resistance and swimming features, the KOSPET TANK T4C is also great for pool training. The watch tracks metrics like SWOLF, average pace, stroke recognition, pool count, stroke rate and heart rate while swimming. This gives you an overview of not just your overall activity, but also your performance in the water.
LED torch with 5 brightness levels
The practical built-in LED torch helps out when you need a quick light without reaching for your phone. It offers 5 brightness levels, so you can use it for work in low-light conditions, evening walks, camping, or everyday situations at home and on the go. Its placement right on the watch means it's always at hand.
Walkie-talkie for quick communication
The walkie-talkie feature enables fast communication between compatible watches. It's useful for group work, hiking, cycling, or when you're out in the field and need to talk quickly without pulling out your phone. Communication can take place between up to four devices, with the actual range depending on the environment, obstacles, and surrounding conditions.
GPS and 6 satellite systems
KOSPET TANK T4C supports GPS and six satellite systems – GPS, Galileo, GLONASS, BeiDou, QZSS, and NavIC. This helps you track your route during outdoor activities like running, walking, hiking, or cycling. The watch records your route and offers a return-to-start function, which is invaluable when navigating unfamiliar terrain. For outdoor activities, you’ll appreciate the compass, barometric altimeter, and air pressure monitoring. The watch displays your direction, current altitude, and changes in barometric pressure, helping you to better understand your surroundings. It also provides information on the weather, moon phase, tides, and sunrise and sunset times.
Over 170 sports modes
The KOSPET TANK T4C smartwatch supports over 170 free training modes, making it easy to adapt to different types of exercise. You can use it for walking, running, cycling, swimming, yoga, weight training, and other activities. The watch tracks important data such as steps, distance, calories, pace, heart rate, and heart rate zones.
Continuous health tracking
KOSPET TANK T4C is equipped with a 4PD health sensor that tracks key indicators throughout the day and during exercise. The watch monitors heart rate, blood oxygen SpO₂, stress, mood, and sleep. It also offers alerts for unusually high or low heart rates and low blood oxygen levels. The one-touch measurement lets you quickly check selected values in one place.
Sleep and recovery overview
The watch helps you track your sleep quality, including deep, light, and REM sleep, as well as short naps during the day. In the Apexmove app, you can get a more detailed overview of your sleep duration and patterns and set your own sleep schedule. This gives you a better insight into how your resting habits are changing and how sleep relates to your recovery.
Long battery life
The 500mAh battery provides up to 12–15 days of typical use. With more intensive use, the watch lasts for approximately 8–10 days, with the Always-On Display mode for around 3–5 days, and up to 18–21 hours with continuous GPS use. Charging is done via a magnetic charging dock and takes about 2 hours for a full charge.
Apexmove OS and the Apexmove app
The Apexmove OS offers intuitive controls and connects with the Apexmove app. In the app, you can track health and sports data, customise watch faces, work with training plans, and tailor the watch's environment to your needs. It also supports synchronisation with Apple Health and Strava.
Watch faces and interface customisation
KOSPET TANK T4C lets you customise the look of the watch face and the interface to suit your preferences. In the Apexmove app, you can choose from a range of watch faces, set your own picture, use an AOD watch face, or customise the shortcut cards. This makes it easy to match your watch to your sports mode, workday, or everyday wear.
Smart features for every day
The watch features Bluetooth 5.3, a built-in microphone and speaker, so it supports Bluetooth calls and notifications from your phone. It displays notifications from apps, SMS messages, and incoming calls, and also supports quick replies on Android devices. It also includes an alarm, calculator, calendar, music controls, camera controls, Find Phone, SOS, Do Not Disturb mode, stopwatch, timer, voice assistant, world time, and weather.
