You work in tough environments, from dusty workshops to remote hiking trails. The Kospet Tank M4C smartwatch matches your lifestyle with rugged durability. Its IP69K rating and 5 ATM water resistance protect against dust, high-pressure jets, and submersion. The steel-reinforced body and scratch-resistant screen survive drops and scrapes.
This smartwatch helps you move faster. The vibrant 1000-nit AMOLED display stays readable in blinding sunlight, so you glance at stats without breaking stride. Built-in GPS precisely maps your route, while the heart rate sensor and SpO2 monitor track your effort. A barometer and altimeter provide real-time elevation data for climbing.
Stay connected without reaching for your phone. Take calls via Bluetooth, activate the voice assistant, and check notifications on your wrist. The battery lasts up to 16 days in standard mode, so you rarely charge it. Whether you log training effect after a swim or set a timer between sets, the Tank M4C adapts to your day.
