What customers don't like about Matrix PowerWatch X

  • Extremely bulky and thick design (50mm case) that may not suit smaller wrists.
  • Limited smart features, with notifications only showing icons rather than full message content.
  • Basic fitness tracking lacking essential sensors like GPS and heart rate monitoring.
  • Unreliable Bluetooth connectivity and buggy data syncing between the watch and the mobile app.
  • Weak backlight that is difficult to use in low-light environments.
  • High price point relative to competitors that offer significantly more functionality.

Verdict

The Matrix PowerWatch X is a rugged, 50mm industrial-style smartwatch distinguished by its thermoelectric technology that generates power from body heat, theoretically offering infinite battery life without traditional charging. It features a 1.2-inch monochrome always-on reflective display, an Ambiq Apollo MCU, and a reinforced bezel with a 200-meter water resistance rating. Core capabilities include a proprietary calorie counter, pedometer, sleep tracking, and basic smartphone notifications delivered via vibration. While it excels in power efficiency and durability, its primary drawbacks include a bulky 17mm-thick design, limited notification content, and the absence of high-drain features like GPS, heart-rate monitoring, or a touchscreen.
