allentian K37 Smart Bracelet Grey 29-35mm 70g

Who it fits

The allentian K37 Smart Bracelet in Grey is a wrist-worn companion for men who want call handling, activity tracking and basic health metrics on a single device. It pairs with Android and iOS phones and uses a round TFT touchscreen with a classic buckle silicone strap. The case measures 29-35mm across and weighs 70g, making it a compact option for everyday wear.

Sustained daily use

Continuous heart-rate, blood-oxygen and blood-pressure sensors run alongside step counting and sleep monitoring throughout the day and night. Bluetooth calling and smart reminders keep the display active, while the life-waterproof rating handles sweat and splashes. Wireless charging replenishes the battery without cable wear, and the aluminium-alloy case resists daily knocks during workouts or outdoor tasks.

Check before ordering

Verify that your phone runs a compatible Android or iOS version for the companion app. Confirm the 29-35mm case diameter suits your wrist and that the classic buckle strap can be adjusted to fit. Ensure you can place the watch on its wireless charger regularly, as no wired cable is included. Buyers needing built-in GPS mapping or third-party app installation should look elsewhere.
