The Fossil Gen 6 boots one generation old Wear OS 2 out of the box. Therefore, the new features and functionalities of the Wear OS 3, such as watch face customisation, are missing here. The watch’s built-in GPS tracker is unreliable. It struggles to accurately register the steps, and health-related metrics like sleep tracking and SpO2 measurements are not always correct. The watch’s built-in speaker and microphone works fine with Google Assistant. But for telephony services, the speaker’s muted output is inadequate to attend calls on the go, and the built-in microphone struggles to pick up voice in noisy environments. Lastly, the watch’s on-battery time is far from desirable, especially with always-on display enabled. Thankfully, there is fast-charge support and the watch takes just about an hour to fully charge. But there is no wireless charging support.
