What we like about Tag Heuer Calibre E4

  • Exceptional build quality and luxurious design that mimics high-end mechanical watches
  • Stunning, sharp, and high-contrast AMOLED display with excellent outdoor visibility
  • High-quality watch faces developed by TAG Heuer that offer a professional, premium aesthetic
  • Fast and accurate GPS performance, especially noted in the specialized Golf Edition
  • Comfortable, high-quality strap options with an infinitely adjustable clasp system
  • Improved battery life over previous generations, typically lasting a full day with regular use

What we don't like about Tag Heuer Calibre E4

  • Extremely high price compared to other smartwatches with similar or better technical features
  • Inconsistent heart rate sensor accuracy, particularly during high-intensity or HIIT workouts
  • Older software (Wear OS 2 at launch) and some reported lag or performance bugs
  • Limited long-term value due to planned obsolescence inherent in smartwatch hardware
  • Reported issues with the rubber crown cover falling off and tarnish on charging contacts over time
  • Lack of advanced health features like LTE support or sleep tracking (due to size/weight)

Verdict

The TAG Heuer Connected Calibre E4 is a luxury smartwatch available in 42mm and 45mm case sizes, featuring premium materials like grade 2 titanium or stainless steel, a ceramic bezel, and a high-resolution AMOLED display protected by sapphire crystal. Powered by the Qualcomm Snapdragon Wear 4100+ chipset and running Wear OS, it offers specific fitness and wellness tracking—including a specialized Golf Edition with maps for 40,000 courses—alongside a heart rate monitor, altimeter, GPS, and 50m water resistance. Main pros include its exceptional Swiss-inspired build quality, vibrant always-on display, and comfortable interchangeable strap system, while primary cons include a very high price point, the lack of a blood oxygen (SpO2) sensor or sleep tracking, and battery life that typically requires daily charging.
