Overview
A budget Android/iPhone smartwatch with a 1.8-inch touchscreen, built-in mic and speaker for calls, Alexa access, and over 120 sport modes. Tracks heart rate, SpO2, sleep, and stress with 3ATM water resistance for handwashing or rain, not swimming laps or hot water.
The watch handles calls and Alexa requests through its own microphone and speaker rather than relaying everything to a paired phone app, which is unusual at this price. Health readings for SpO2 and stress are labeled non-medical, so treat them as general trend data rather than clinical numbers. Compatibility is iOS 9.0+ and Android 6.0+ only, with no support for PCs or tablets.
- 1.8-inch touchscreen with customizable photo watch faces
- Built-in microphone and speaker for calls and Alexa
- 350mAh battery: 7 days heavy use, 30 days standby
- 3ATM water resistance for rain and handwashing
Who it's for
Suits someone who wants call and notification access on the wrist plus basic fitness and sleep tracking without paying smartwatch-brand prices. Not for anyone who needs swim tracking, since 3ATM resistance covers rain and handwashing but not pool or hot water use.
Pros and cons

- Alexa access for music, weather, and alarms from the wrist
- 120+ sport modes and 24/7 heart rate, SpO2, and sleep tracking
- 2-year warranty with vendor-provided tech support

Performance notes
A 350mAh battery is rated for 7 days of heavy use, 12 days of typical use, or up to 30 days on standby, with a full charge taking 1.5 to 2.5 hours. The 3ATM water resistance rating covers rain, handwashing, and light splashes but is not rated for swimming or hot water exposure. Heart rate, SpO2, sleep, and stress sensors run continuously, with the manufacturer labeling SpO2 and stress readings as non-medical.
