    Verdict

    The Sony SmartWatch 3 (SWR50) is a sport-focused wearable featuring a 1.6-inch transflective LCD (320x320) that remains highly legible in direct sunlight. It is powered by a 1.2GHz quad-core ARM Cortex-A7 processor with 512MB of RAM, 4GB of internal storage for offline music, and a 420mAh battery offering up to two days of use. Key highlights include built-in GPS for phone-free tracking, NFC, Wi-Fi connectivity, and a high IP68 water and dust resistance rating. Its main advantages are the convenient micro-USB charging port (no proprietary cradle needed) and its robust fitness capabilities. However, notable drawbacks include the lack of a heart rate monitor, poor viewing angles and color vibrancy on the display, and a silicone strap that often attracts lint and dust.
