What the Gt40 smart watch delivers

The allentian Gt40 is a new wearable that combines Bluetooth calling, health monitoring and sports tracking in a single aluminium case. It runs on a TFT touchscreen with button control and offers up to two weeks of battery life between magnetic charges. The life-waterproof build suits daily wear and exercise.

When the Gt40 replaces your current band

If your existing tracker lacks on-wrist calling or only counts steps, the Gt40 adds voice calls, heart-rate monitoring, sleep analysis and smart reminders without needing a phone in hand. The jump is worth it when you want notifications, voice-assistant access and motivational fitness features on a medium-sized sporty strap.

What to verify on your phone before ordering

Confirm your handset runs Android or iOS and supports standard Bluetooth pairing within a five-metre range. Ensure you can charge via the supplied magnetic cable and that a TFT display with touch-plus-button operation matches your preferred interaction style. The European version type ships with a TPU strap in BlackSteel finish.

Questions about this item

What wrist size fits the medium BlackSteel case?

The medium case weighs 128 grams and uses a TPU sport strap that adjusts to most wrists; the aluminium case measures 40 mm wide so you can compare it to your current watch.

How do I pair the GT40 for Bluetooth calling and notifications?

Enable Bluetooth on your Android or iOS phone, open the companion app, select the watch from the device list, then grant call and notification permissions — skipping the permission step is the most common reason calls do not route to the watch.

What parts will need replacement after daily use?

The magnetic charging cable and TPU sport strap are the only wear items; the cable can fray at the connector and the strap may develop cracks, while the sealed aluminium case and TFT screen require no user service.
