What it is and who it's for

The HTC ZenWatch 2 IDW25 is a new smart watch with a 1.04" screen and Bluetooth 5.3 connectivity. It targets users who want call handling, notifications and health tracking from a single wrist device. Built-in Alexa provides voice control for reminders, weather and smart home functions. The watch weighs 1.6 ounces and offers 1 GB of storage expansion.

Upgrade path and when it matters

This watch replaces a basic fitness band that lacks calling or voice assistant features. The jump is worthwhile when you need to answer calls directly from the wrist and view WhatsApp, Telegram or Facebook alerts on a colour touchscreen. It adds continuous heart rate, sleep and blood oxygen monitoring plus over 100 sport modes. Buyers who want a larger 1.83" display or message reply support should look elsewhere.

Installation ease and common pitfalls

Pairing is done through the companion app on a Windows-compatible smartphone; the process is straightforward for most users. A frequent issue is forgetting to grant all notification and phone permissions, which stops alerts and call audio from reaching the watch. Battery life reaches 30 days in standby but drops significantly with daily Bluetooth calling and 24/7 sensor use. The IP68 rating handles sweat and rain but not high-pressure water.

The battery delivers up to 30 days of operating or standby time, so expect a full recharge roughly once a month under typical use.
