What we like about Agptek Smart Watch LW31

  • Excellent battery life (7-10 days of use, 30 days standby)
  • Elegant and stylish design with a high-quality zinc alloy finish
  • Large, bright 1.69-inch HD touch screen suitable for outdoor viewing
  • Comprehensive basic health tracking (heart rate, sleep, steps, blood oxygen)
  • Good value for money as an entry-level fitness tracker
  • IP68 water resistance suitable for swimming and daily use

What we don't like about Agptek Smart Watch LW31

  • Limited smart features: cannot answer calls or reply to messages directly
  • The companion 'OnWear' app receives mixed reviews for syncing and reliability
  • Lack of advanced connectivity like Wi-Fi, NFC, or built-in GPS
  • Some reports of long-term durability issues, such as the screen failing after months
  • No automatic brightness adjustment (must be changed manually)
  • Considered slightly bulky by some users despite its slim profile

Verdict

The AGPTEK Smart Watch LW31 is a budget-friendly wearable featuring a 1.69-inch HD full-touch color screen with a 240x280 resolution, housed in a zinc alloy body with an IP68 waterproof rating. It serves as a comprehensive fitness tracker by supporting 11 sports modes and 24-hour health monitoring for heart rate, sleep quality, blood oxygen levels, and female-specific health metrics. Key advantages include an impressive battery life of 7–10 days on a single 2-hour charge, high compatibility with iOS 10.0 and Android 5.0 or above via Bluetooth 5.0, and a lightweight, premium design with over 100 customisable watch faces. However, notable drawbacks include the inability to directly answer calls or reply to text messages from the watch, the lack of built-in GPS, and occasional reports of intermittent Bluetooth connectivity or charging issues.
