Third-party reviews

What customers like about Tag Heuer Calibre E3

  • Iconic TAG Heuer Swiss watch design and craftsmanship
  • High-quality materials including titanium/steel cases and ceramic bezels
  • Sharp and vibrant 1.39-inch OLED display with sapphire crystal
  • Seamless integration and customization through the dedicated TAG Heuer Sports app
  • Excellent ergonomic physical controls with two pushers and a rotating crown
  • Interchangeable strap system that is easy to use and very comfortable

What customers don't like about Tag Heuer Calibre E3

  • Short battery life often requiring daily charging, especially when using GPS
  • High price compared to smartwatches with similar or more advanced tech specs
  • Limited fitness data customization on the watch faces compared to dedicated sports watches
  • Reduced functionality when paired with iPhones (e.g., cannot reply to notifications)
  • Lack of 'Swiss Made' certification (manufactured in China)
  • Concerns over long-term value and rapid technological obsolescence

Verdict

The TAG Heuer Connected Calibre E3 is a premium 45mm smartwatch featuring a high-resolution OLED display protected by scratch-resistant sapphire crystal and housed in a 15.27mm thick stainless steel or titanium case with a ceramic bezel. Key characteristics include a 440 mAh battery providing roughly 20 hours of life (full day), 50m water resistance, and a comprehensive sensor suite including GPS, heart rate, compass, and accelerometer. It runs on Wear OS, offering specialized sports tracking for golf, running, and cycling via dedicated TAG Heuer apps. Main pros are its luxury Swiss craftsmanship that mimics a traditional mechanical watch, a quick-change strap system, and a smooth, premium haptic feedback experience. However, notable cons include its high luxury price point compared to other Wear OS devices and a battery life that requires daily charging, which may be insufficient for multi-day use without its magnetic charger.
