TAG Heuer Connected Calibre E5 – 45 mm – DLC Titanium – 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 forward in the union of watchmaking emotion and digital innovation.

Guided by its philosophy “Emotion Beyond Technology,” TAG Heuer does not consider the connected watch as a mere high-tech gadget, but as a true horological instrument, carrying history, style, and performance.
Every detail – from the case design to the ergonomics of the interface – reflects the desire to create a watch that resonates with mechanical watch enthusiasts as much as with those seeking connectivity and sporting performance.

The fifth-generation Calibre E5 goes beyond adding new features: it redefines the user experience with a redesigned interface, smoother navigation, and enhanced performance, while preserving the aesthetics and quality of finishing that are hallmarks of TAG Heuer.

In this 45 mm black DLC-coated titanium version on a black rubber strap, the Connected Calibre E5 embodies TAG Heuer’s watchmaking DNA in a truly sporty, lightweight, and modern design, built to accompany its wearer from daily routines to the most demanding activities.

Design & Hardware

The TAG Heuer Connected Calibre E5 – 45 mm in black DLC-coated titanium on a black rubber strap reflects the fusion of Swiss watchmaking expertise and cutting-edge connected innovation.
Its Grade 2 titanium case, treated with black DLC (Diamond-Like Carbon), combines lightness, shock resistance, and contemporary aesthetics, emphasizing the technical and sporty character of this edition.

An ultra-light case

The 45 mm black DLC titanium case, lighter than steel and particularly resistant, showcases TAG Heuer’s expertise in high-performance sports watches.
The polished black ceramic bezel, engraved with grey indexes, evokes the world of sports chronographs and offers excellent scratch resistance.
The crown, adorned with the TAG Heuer logo, ensures smooth and precise handling, even during activity.
The two redesigned pushers provide better grip and a crisper click, facilitating access to essential functions and reinforcing the link to the design language of mechanical chronographs.
The watch is protected by a flat sapphire crystal, ensuring long-lasting durability and excellent readability.
With water resistance up to 50 meters, it is ready to handle both daily challenges and outdoor activities.

Readability and comfort

The high-definition AMOLED display (454 × 454 px), bright and vibrant, faithfully reproduces the details of digital watchfaces, with deep blacks and vivid colors.
Adaptive brightness automatically adjusts screen intensity for optimal visibility in bright sunlight or low-light conditions.
The perforated black rubber strap, lightweight, breathable, and flexible, enhances the sporty and technical character of this edition.
It ensures optimal comfort, even during extended activity or outdoor adventures.
Thanks to the TAG Heuer quick-release system, the strap can be easily swapped for another style.

Technology at the core

Beneath its watchmaking exterior lies a concentration 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 areas, forests, or mountainous terrain.
• Advanced biometric sensors for precise performance and health tracking:
  • Next-generation optical heart rate (PPG) sensor for more stable and accurate measurement,
  • SpO₂ sensor for measuring blood oxygen saturation,
  • HRV (heart rate variability) tracking for stress and recovery analysis,
  • Sleep tracking with detailed analysis of sleep stages,
  • Barometric altimeter for tracking elevation gain,
  • Compass and gyroscope for orientation and measurement stability during movement.

This combination makes the watch a true performance companion, delivering accurate data for athletes as well as for daily wellness tracking.

Battery life and charging

Optimized power management allows up to 2 days of full use and up to 3 days in Low Power mode.
Fast charging ensures the watch is always ready to go:

• 30 minutes of charging provides around 1 day of use,
• a full charge is reached in just 90 minutes.

Watch Experience & Software

While the Connected Calibre E5 impresses with its watchmaking aesthetics, it also stands out thanks to a completely redesigned software experience.
TAG Heuer has developed an interface that reflects the elegance of a Swiss timepiece while delivering the smoothness and functionality expected from a premium connected watch.

Redesigned TAG Heuer OS

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

• Smoother navigation with faster transitions between apps and watchfaces,
• Simplified, more visual menus designed for intuitive wrist interaction,
• Improved responsiveness when launching apps or tracking sports activities.

Personalization and watchfaces

The watchmaking spirit of TAG Heuer is expressed through an exclusive collection of digital watchfaces.
These designs draw inspiration from the brand’s iconic chronographs, such as the Carrera, Monaco, and Aquaracer, with the same attention to detail and finishing.

• Customizable complications allow users to display the most relevant information (battery level, heart rate, weather, sports progress, etc.).

Sports, Outdoor, and TAG Heuer Wellness

Designed to be a true performance partner, the Connected Calibre E5 leverages its dual-band GNSS (L1 + L5) and advanced biometric sensors to provide precise and 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 into activities,
• Dual-band GNSS for precise route tracking, even in challenging environments,
• Direct integration with the TAG Heuer Sports app to review history, compare performance, and adjust training plans.

For daily health and wellness:

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

• Daily activity tracking (steps, calories burned, active time),
• Continuous heart rate monitoring (at rest, during effort, and recovery),
• HRV (heart rate variability) measurement, a key indicator for stress and recovery management,
• Detailed sleep analysis: duration, cycles, deep and light phases,
• Recovery and balance indicators to avoid overtraining and improve quality of life,
• Progress dashboards and personalized goals visible directly on the watch or in the TAG Heuer Wellness app.

This comprehensive ecosystem makes the Calibre E5 much more than a connected watch: it is a premium health and performance tracking tool, designed for fitness enthusiasts as well as those looking to better understand their condition and daily habits.

Complete connectivity

Designed for seamless integration into daily life, the Connected Calibre E5 offers:

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

All these features are presented within a clear interface, ensuring the watch remains practical and intuitive without becoming an intrusive gadget.
