Everyday health companion

The allentian Ks03 Smart Watch in AllBlack Medium weighs 160 g and fits Android and iOS phones. It tracks steps, heart rate, sleep and body temperature while also handling Bluetooth calls and intelligent reminders. Voice assistants add hands-free convenience for busy users.

Battery and connection limits

The magnetic-charging cell lasts less than 7 days on a full charge. Wireless range tops out at 5 m, so the paired phone must stay nearby for calls and notifications to function. Life-waterproof rating protects against sweat and rain but not swimming or submersion.

Aluminium case with silicone sport strap

An aluminium alloy case and TFT touchscreen combine with a silicone sport strap for a secure, lightweight feel during workouts. Touch-plus-button operation works with sweaty fingers, while the magnetic cable snaps on without fumbling. The common-mold design keeps the profile slim for all-day wear.

Questions about this item

Which colour version of the allentian Ks03 should I choose?

The watch is offered in AllBlack and Silver And Black; the Medium size and sporty silicone strap are the same on both, so pick the finish you prefer.

What does the 160 g weight mean when I wear the watch daily?

At 160 g the aluminium-alloy case and TFT screen feel noticeable but not heavy on the wrist, comparable to a mid-size sports watch.

How does the magnetic charging and 5 m wireless range work in practice?

The magnetic cable snaps on for charging, and the Bluetooth link stays stable up to about 5 metres from your phone for calls and notifications.
