Everyday wearable with 1.3in display

The OEM Tools D13 smart watch uses a 1.3-inch colour touchscreen for clear readouts and smooth operation. It pairs with Android and iOS devices over Bluetooth 4.0 to deliver call alerts, message notifications from Facebook, Twitter, WeChat and WhatsApp, plus sedentary reminders and alarm functions. A metal case and skin-friendly silicone band fit wrists from 160mm to 240mm for comfortable all-day wear. The IP67 rating handles everyday splashes and brief immersion.

Plug-in USB charging and health sensors

The strap detaches to reveal a direct USB plug so the 80mAh battery recharges without a proprietary cable, reaching up to seven days standby. An optical heart-rate sensor tracks pulse around the clock and logs trends in the companion app, while the watch also reports blood-oxygen levels and sleep patterns. Vibration alerts keep notifications discreet, and the touch button adds a layer of accidental-press protection.

Tracks core fitness metrics not medical data

The D13 comfortably handles step counting, calorie estimation, sleep management and continuous heart-rate monitoring for general wellness awareness. It is not a medical device and cannot diagnose heart or blood-pressure conditions; buyers who need clinical-grade accuracy should use approved healthcare equipment. The 39.8mm square dial and 260mm band suit most adult wrists, but the fixed 80mAh cell limits multi-day heavy GPS or music use.

Questions about this item

How often will the 80mAh battery need recharging under normal use?

The 80mAh battery provides up to 7 days of standby time before requiring a recharge via the built-in USB plug.

What limits continuous heart-rate tracking during all-day wear?

Continuous optical heart-rate monitoring relies on the 80mAh capacity, so the battery will deplete faster than the 7-day standby figure.

How warm or noisy does the device get when worn 24 hours a day?

The watch has no fan or moving parts, runs silently, and the TPU band stays skin-friendly without noticeable heat buildup.
