Watches TAG Heuer Connected Calibre E5: Emotion Beyond Technology

With the TAG Heuer Connected Calibre E5, TAG Heuer brings the codes of Swiss luxury watchmaking into the digital age — combining fine materials, bold design, and mechanical inspiration with the possibilities of wearable technology. Available in 45mm and 40 mm, in steel, titanium, or rose gold, the collection reflects the same high standards as the Maison’s icons. Straps in rubber, leather, or self-fastening textile, add versatility, while a growing palette of colors expands the scope of personal expression.

At its core lies an exclusive collection of digital watch faces inspired by the TAG Heuer Monaco, Carrera, or Aquaracer — fusing digital functionality with a visual language that has defined TAG Heuer for decades.

The TAG Heuer Connected Calibre E5 runs on TAG Heuer OS, a proprietary operating system developed entirely in-house. It offers a fluid, intuitive interface designed for seamless navigation: managing calls, accessing a voice assistant, or checking widgets for heart rate, activity, sleep, or weather.

Battery life reaches up to three days (45mm) or two days (40mm) in low-power mode, with a full day’s charge achieved in just 30 minutes. Certified under Apple’s MFi program, the TAG Heuer Connected Calibre E5 ensures reliable iPhone connectivity across ecosystems and lifestyles.

TAG Heuer has always gone beyond the stopwatch. With the TAG Heuer Connected Calibre E5, it transforms invisible rhythms into actionable insights. Wellness tracking covers calories, steps, active minutes, and advanced heart-rate monitoring — live, minimum, maximum, resting, and workout data. Sleep tracking captures phase cycles, breath rate, SpO₂, and heart-rate variability, turning rest into a measurable asset for performance.

The redesigned interface makes progress tangible through goals, daily stats, and weekly graphs — giving athletes and everyday wearers the tools to surpass their limits.

Running sits at the heart of the TAG Heuer Connected Calibre E5 experience. The watch integrates six exclusive training plans developed with New Balance, bringing structured guidance from a first 5K to a full marathon directly to the wrist. Gamified displays keep every step engaging, from warm-up to recovery, while enhanced screen readability ensures clarity even mid-stride. Dual-frequency GPS delivers pinpoint accuracy on pace and distance, and battery life — up to 17 hours on the 45mm model — lasts through the longest runs. With the TAG Heuer Connected Calibre E5, preparation becomes visible, measurable, and motivating — a true partner for every runner chasing progress.

For golfers, the dedicated TAG Heuer Golf app offers a new hole layout display, a smarter auto-scoring algorithm, and fast GPS convergence.

Whether chasing a personal best, recovering from intense effort, or staying connected on the move, the TAG Heuer Connected Calibre E5 is engineered as a partner in ambition.

The TAG Heuer Connected Calibre E5 generation carries forward the avant-garde philosophy that created icons like the Carrera and the Monaco. That same spirit of innovation now takes shape in silicon, sensors, and algorithms through a new timekeeping language, rooted in the Maison’s DNA.

For TAG Heuer, the future of watchmaking is defined by convergence. Mechanical mastery and digital intelligence share the same horizon. The TAG Heuer Connected Calibre E5 is proof: technology may keep time, but it is human emotion that gives it meaning.
