  • Elegant and premium traditional watch-inspired design
  • Vibrant 1.39-inch AMOLED display with no 'flat tire' effect
  • HyperCharge technology providing 60% charge in about 15 minutes

  • IP67 water resistance suitable for rain and splashes

What customers don't like about ASUS ZenWatch 3 WI503Q

  • Inconsistent battery life that often requires daily charging
  • Occasional sluggish performance or lag with Android Wear software
  • Lack of NFC, preventing the use of mobile payment services like Google Pay
  • Fixed-angle band design can feel rigid on very small or non-standard wrists

Verdict

The ASUS ZenWatch 3 WI503Q is a circular Android Wear smartwatch featuring a 1.39-inch AMOLED display with a 400x400 resolution (287 ppi) and Gorilla Glass 3, housed in a 316L stainless steel frame. Powered by a Qualcomm Snapdragon Wear 2100 processor with 512MB of RAM and 4GB of storage, it includes three physical side buttons, a 340mAh battery with HyperCharge fast-charging (60% in 15 minutes), and IP67 water resistance. Main pros include its elegant, jewelry-grade design, vibrant display, and highly responsive customisable buttons for app launching. However, significant cons include the absence of a heart rate monitor and GPS, proprietary lug design that limits strap options, and sluggish performance or decreased battery life when updated to newer software versions.
