TAG Heuer Connected Calibre E5 – 40 mm – Steel – Black rubber strap

Connected by TAG Heuer

Since the launch of the first TAG Heuer Connected in 2015, the Maison has shaped a unique vision of connected watchmaking: combining the timeless elegance of a Swiss timepiece with the power of modern technology.
Ten years later, the new Connected Calibre E5 embodies this quest for perfection, taking a new step in the union between watchmaking emotion and digital innovation.

Guided by its philosophy “Emotion Beyond Technology”, TAG Heuer does not conceive the connected watch as a simple high-tech device, but as a true horological instrument, carrying history, style, and performance.
Every detail – from the case design to the interface ergonomics – reflects this desire to create a watch that speaks to both mechanical watch enthusiasts and lovers of connectivity and athletic performance.

The fifth-generation Calibre E5 does more than add new features: it reinvents the user experience, offering a redesigned interface, smoother navigation, and enhanced performance, all while retaining the aesthetics and finishing quality inherent to TAG Heuer.

In this 40 mm stainless steel version with a rubber strap, the Connected Calibre E5 captures TAG Heuer’s watchmaking DNA in a format that is both refined, versatile, and sporty.
More compact and lighter than the 45 mm model, it is designed to fit all wrists and accompany its wearer from daily life to sports activities, while maintaining a modern, streamlined elegance.

Design & Hardware

The TAG Heuer Connected Calibre E5 – 40 mm in stainless steel with a rubber strap showcases the fusion of Swiss watchmaking expertise and the latest in connected innovations.
It adopts a sleek, contemporary style, equally at home in a sporty context or an urban setting.
This 40 mm format is particularly well suited for those seeking a balance between comfort, style, and performance.

A case inspired by traditional watchmaking

The 40 mm polished and brushed stainless steel case, more compact and lighter than the 45 mm version, is designed for natural, all-day comfort.
The absence of a bezel enhances the clean design and highlights the domed sapphire crystal, providing excellent readability from all angles and durable protection against scratches.
The crown, adorned with the TAG Heuer logo, ensures smooth and precise handling, even on the move.
The two redesigned pushers offer a better grip and a crisper click, facilitating quick access to essential functions while maintaining the aesthetic link to TAG Heuer’s mechanical chronographs.
With 50 meters of water resistance, the watch is ready to face everyday challenges and outdoor activities.

Readability and comfort

The 390 × 390 px HD AMOLED display delivers vivid colors, deep blacks, and excellent contrast, faithfully reproducing the details of digital dials.
Adaptive brightness automatically adjusts to ensure optimal visibility in bright sunlight or low-light environments.
The black rubber strap, supple and breathable, enhances the technical and sporty character of this edition.
Designed for maximum wrist comfort, it adapts perfectly to long days and training sessions.
Thanks to the TAG Heuer quick-release system, it can be easily swapped for a steel or leather strap, allowing seamless transitions from a sporty look to a more refined style.

Cutting-edge technology

Beneath its watchmaking exterior lies a wealth of advanced technology:

• Qualcomm Snapdragon 5100+ processor: delivers smooth, responsive navigation while optimizing power consumption.
• Dual-band GNSS (L1 + L5): ensures ultra-precise GPS tracking, even in dense urban environments, forests, or mountainous terrain.
• Advanced biometric sensors for precise tracking of performance and wellness:
  • Next-generation optical heart rate sensor (PPG), improved for more stable and accurate readings.
  • SpO₂ sensor for measuring blood oxygen saturation.
  • HRV (heart rate variability) tracking for stress and recovery analysis.
  • Sleep tracking and phase analysis for rest optimization.
  • Barometric altimeter for recording elevation changes.
  • Compass and gyroscope for orientation and enhanced motion tracking.

This combination transforms the watch into a true performance companion, providing precise data for athletes as well as for daily wellness tracking.

Battery life and charging

Optimized power management allows up to 1.5 days of full usage and up to 2 days in Low Power mode.
Fast charging ensures the user never slows down:

• 40 minutes provide approximately 1 day of battery life,
• a full charge is achieved in just 90 minutes.

Watch Experience & Software

While the Connected Calibre E5 impresses with its watchmaking aesthetics, it also stands out for its completely redesigned software experience.
TAG Heuer has created an interface that reflects the elegance of a Swiss timepiece while offering the fluidity and advanced functionality expected from a high-end connected watch.

Redesigned TAG Heuer OS

The fifth-generation Calibre E5 introduces a completely redesigned TAG Heuer OS, developed in-house by the Maison.
The interface is smoother, more responsive, and intuitive, thanks in particular to the Qualcomm Snapdragon 5100+ processor and optimized software.

• Smooth navigation: faster transitions between apps and watch faces.
• Simplified, more visual menus designed for intuitive wrist use.
• Enhanced responsiveness when launching apps or tracking sports activities.

Customization and watch faces

The watchmaking soul of TAG Heuer shines through a collection of exclusive digital dials.
These dials draw inspiration from the iconic TAG Heuer chronographs, such as the Carrera, Monaco, and Aquaracer, with the same attention to detail and finish.

• Customizable complications: users can display key information on the dial (battery life, heart rate, weather, sports progress, etc.).

Sports, Outdoor and TAG Heuer Wellness

Designed to be a true performance partner, the Connected Calibre E5 relies on its dual-band GNSS (L1 + L5) and advanced biometric sensors to provide accurate, actionable data.

For sports and outdoor activities:

• Advanced tracking for multiple disciplines: running, cycling, swimming, hiking, golf, and training.
• Real-time metrics: distance, pace, speed, elevation gain, heart rate zones, integrated directly into activity tracking.
• Dual-band GNSS ensures precise route tracking, even in challenging environments.
• Direct integration with the TAG Heuer Sports app to visualize history, compare performance, and adjust training plans.

For daily wellness and health:

The TAG Heuer Wellness suite turns the watch into a discreet yet effective coach.

• Daily activity tracking (steps, calories burned, active time).
• Continuous heart rate monitoring (resting, effort, recovery).
• Heart rate variability (HRV) analysis, a key indicator for stress and recovery tracking.
• Detailed sleep analysis: duration, stages, deep and light sleep phases.
• Recovery and balance indicators to prevent overtraining and improve quality of life.
• Progress charts and personalized goals, viewable directly on the watch or in the TAG Heuer Wellness app.

This comprehensive ecosystem makes the Calibre E5 far more than a connected watch: it is a high-end health and performance tracking tool, designed for regular activity enthusiasts and for those who want to better understand their health and habits.

Complete connectivity

Designed to integrate seamlessly into daily life, the Connected Calibre E5 offers:

• Call management when paired with a compatible smartphone,
• Notifications,
• Media controls to manage music and audio content without reaching for the phone.

All these functions are presented in a clear, intuitive interface, ensuring the watch remains a practical and efficient tool without becoming an intrusive gadget.
