HTC D3B Smart Watch 1.85" AMOLED

The HTC D3B is a lightweight smart watch built for daily health tracking and smartphone connectivity. It suits adults who want continuous heart-rate and blood-oxygen monitoring plus the ability to handle calls from the wrist.

128 MB storage and 100-plus sport modes

Onboard storage of 128 MB holds activity logs and firmware data without needing a phone nearby. Over one hundred sport modes let the watch auto-detect workouts such as walking, running or cycling and record calories, steps and distance for each session.

IP68 waterproof and Bluetooth pairing

The IP68 rating protects the 1.85-inch AMOLED screen and sensors during hand-washing, rain or sweat-heavy exercise. Pairing is a standard Bluetooth link to a smartphone; the only common snag is forgetting to grant the companion app notification and phone-call permissions on the phone side.

商品問答

How often will the 128 MB internal storage need clearing or replacement?

The 128 MB storage is fixed and non-expandable; it holds firmware and activity logs, so no user replacement is needed.

What limit appears first during continuous heart-rate and SpO2 tracking?

Continuous 24/7 sensor use will drain the battery before any other component reaches a limit.

Does the IP68-rated case get hot or noisy during all-day wear?

The watch has no fan or moving parts, runs silent, and stays at skin temperature during 24/7 monitoring.
