K65 FAQs

Can the K65 make and receive phone calls?

Yes. The K65 supports Bluetooth calling: once paired with your phone you can answer, reject and make calls from the watch using its built-in microphone and speaker. Keep your phone within Bluetooth range, around 10 metres.

Is the K65 waterproof?

The manufacturer does not list an IP water-resistance rating, so treat it as splash-safe only and take it off before washing up, showering or swimming.

How long does the battery last?

Expect around 5–10 days of typical use from its 530 mAh battery. Bright screens, always-on display, frequent calls and continuous heart rate tracking use more power. See our smartwatch battery life guide for tips.

Does the K65 work with iPhone and Android?

Yes, it is compatible with iOS and Android phones via the companion app.

Are the health readings medically accurate?

No smartwatch in this range is a medical device. Heart rate, blood oxygen, blood pressure, temperature and similar readings are estimates to help you spot trends in your general fitness and wellbeing. They are not suitable for diagnosing or managing a medical condition, so always speak to a healthcare professional about health concerns.
