Smart Watch for Android and iOS

The OEM Tools smart watch pairs with Android and iOS devices over Bluetooth 4.0 and uses a touch-controlled rectangular LED dial. It tracks steps, calories, distance and running trajectory during exercise while continuously monitoring heart rate. The alloy and resin case measures approximately 25 cm in total length with a 4 cm dial diameter and 1 cm thickness. A silicone band with buckle clasp secures the 30 g unit to the wrist.

Standalone fitness tracker with phone notifications

No separate charging cable is required; the watch plugs directly into a USB port or charging head for power. The 170-200 mAh battery supports daily activity logging and heart-rate recording without a tethered phone. Water resistance is limited to hand-washing and face-washing; the device must be removed before bathing, swimming or diving. All data is viewed on the watch screen or synced to the companion app after a workout.

Low-power wearable for all-day wear

Bluetooth 4.0 and the small LED display keep power draw modest so the 170-200 mAh cell lasts through normal daily use. The lightweight 30 g construction and smooth silicone band produce no audible noise and generate negligible wrist heat during continuous wear. Because the watch is not rated for immersion, moisture from heavy sweat or rain should be wiped off promptly to maintain reliable skin contact for the heart-rate sensor.

The watch has no fan or moving parts, so it runs silently and stays at skin temperature during normal use.
