Designed for active men

The allentian K55 smart watch in green targets men who want a compact wrist device for daily fitness tracking and smart notifications. Its 29-35 mm square aluminium alloy case weighs 160 g and fits a sporty silicone strap. Compatibility covers Android and iOS platforms.

Touch and button operation

Operation relies on a touchscreen plus a physical button, so no proprietary dock or special app is required beyond standard Bluetooth pairing. The magnetic charging cable snaps on quickly, freeing you from fiddly ports. An IPS display keeps data readable in bright conditions.

Life waterproof rating

The watch carries a life waterproof grade suitable for sweat, rain and hand washing but not for swimming or diving. Battery life stays under seven days per charge, so weekly top-ups are normal. Sensors handle heart rate, blood pressure, blood oxygen and body temperature without active cooling.
