Green 1.3-inch Smart Watch for Daily Fitness

The OEM Tools D13 is a wearable technology device with a 1.3-inch colour touchscreen that shows larger text and responds to tap input. It pairs with Android and iOS phones through Bluetooth 4.0 to deliver call alerts, message previews and music control from the wrist. A vibration motor provides silent notifications for apps such as Facebook, WhatsApp and Twitter.

Upgrade from Basic Bands Without Sensors

Moving up from a simple step counter adds continuous heart-rate tracking, blood-oxygen spot checks and automatic sleep analysis recorded in the companion app. The jump is worth it when you want 24-hour health trends rather than only daily step totals. Buyers who need clinical-grade blood-pressure accuracy or medical diagnostics should not rely on this device.

80 mAh Battery Handles a Week of Tracking

The 80 mAh cell delivers up to 7 days of standby time while running heart-rate, sleep and notification features. Daily charging is not required for typical use. Users who want always-on display mode or multi-day GPS logging will find the capacity runs out sooner.
