A smartwatch can track your health, show notifications and even take calls. With so many models, here is what to check before you buy.
1. Compatibility
Make sure the watch works with your phone. Most budget and mid-range watches support both Android and iPhone, but some features work best on one platform. Check the supported OS version on the product page.
2. Display
A bright screen (500 nits or more) is easier to read outdoors. AMOLED displays have deeper colours; TFT screens are common on budget models and still work well.
3. Health and fitness tracking
- Heart rate and SpO2 (blood oxygen) monitoring
- Sleep tracking
- Step count and sports modes
These readings are helpful for everyday wellness, but a smartwatch is not a medical device. Speak to a doctor about any health concerns.
4. Bluetooth calling
Watches with a built-in mic and speaker let you answer calls from your wrist when your phone is nearby. It is handy when driving or cooking.
5. Battery life and water resistance
Many smartwatches last 5 to 7 days on a charge; always-on displays and calling use more battery. IP67 or IP68 protects against sweat, rain and hand-washing.
