TAG Heuer Connected Calibre E5 – 45 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 pursuit of perfection, taking another step forward in the fusion of watchmaking emotion and digital innovation.

Guided by its philosophy “Emotion Beyond Technology”, TAG Heuer does not see the connected watch as a mere high-tech gadget, but as a true watchmaking instrument, imbued with heritage, style, and performance.
Every detail – from the case design to the interface ergonomics – reflects the brand’s aim to create a watch that resonates both with mechanical watch enthusiasts and those passionate about connectivity and sports performance.

The fifth-generation Calibre E5 does not merely add new features: it reinvents the user experience, with a redesigned interface, smoother navigation, and enhanced performance, while preserving the aesthetics and craftsmanship that define TAG Heuer.

In this 45 mm steel version with a rubber strap, the E5 fully expresses the brand’s DNA: a blend of sporty elegance and refined design, ready to accompany users from daily life to their most demanding activities.

Design & Hardware

The TAG Heuer Connected Calibre E5 – 45 mm steel with rubber strap illustrates the brand’s watchmaking heritage while incorporating cutting-edge innovation.
It draws inspiration from the iconic aesthetic codes of TAG Heuer’s mechanical collections, reaffirming its identity as a genuine watch first.

A case inspired by traditional watchmaking

The 45 mm polished and brushed steel case reflects the craftsmanship of TAG Heuer’s sports watches: with its sharp lines, meticulous finishing, and proven robustness.
The polished black ceramic bezel, engraved with silver markers, evokes the sport chronograph universe and offers excellent scratch resistance.
The crown, adorned with the TAG Heuer logo, ensures smooth and precise handling, even on the move.
The two redesigned side pushers, with improved grip and a more tactile click, provide easy access to key functions and reinforce the link with the mechanical chronograph language.
The whole is protected by a flat sapphire crystal, guaranteeing readability and durability over time.
With a 50-meter water resistance, the watch is ready to face the challenges of both daily life and outdoor activities.

Readability and comfort

The 454 × 454 px AMOLED HD display, with its bright and high-contrast visuals, faithfully reproduces the details of digital watch dials, delivering deep blacks and vivid colors.
Its adaptive brightness automatically adjusts for optimal visibility, whether in bright sunlight or low-light conditions.
The perforated black rubber strap, lightweight and breathable, ensures lasting comfort, even during extended activity.
Thanks to the TAG Heuer quick-change system, the strap can be easily swapped, allowing the wearer to adapt the watch’s style to any occasion.

Technology at its core

Beneath its watchmaking exterior lies a concentration of advanced technology:

• Qualcomm Snapdragon 5100+ processor: delivers smooth, responsive navigation while optimizing energy consumption.
• Dual-band GNSS (L1 + L5): ensures ultra-precise GPS tracking, even in dense urban environments, forests, or mountainous terrain.
• Advanced biometric sensors for accurate tracking of performance and health:
  • Next-generation optical heart rate sensor (PPG) – enhanced 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 with detailed analysis of rest phases.
  • Barometric altimeter for recording elevation changes.
  • Compass and gyroscope for orientation and motion stability.

This combination transforms the watch into a reliable performance companion, capable of delivering accurate data for both athletes and those focused on daily wellness tracking.

Battery life and charging

The optimized energy management allows for up to 2 days of use in standard mode and up to 3 days in Low Power mode.
The fast-charging system is designed to keep up with your lifestyle:

• Just 30 minutes to recover about 1 day of use.
• A full charge is achieved in only 90 minutes.

Watch Experience & Software

While the Connected Calibre E5 impresses with its watchmaking-inspired design, it also stands out for its completely redesigned software experience.
TAG Heuer has developed an interface that reflects the elegance of a Swiss timepiece while offering the fluidity and feature-rich performance expected from a premium connected watch.

Redesigned TAG Heuer OS

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

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

Customization and watch faces

The watchmaking soul of TAG Heuer shines through a collection of exclusive digital watch faces.
These faces take inspiration from the iconic design codes of the brand’s legendary chronographs, such as the Carrera, Monaco, and Aquaracer, with the same attention to detail and refined finishes.

• Customizable complications: users can display the most relevant information (battery, heart rate, weather, sport progress…) right on their watch face.

Sport, 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 deliver precise, 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, and heart rate zones integrated into each activity.
• Utilization of 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 optimize training.

For daily wellness and health:

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

• Daily activity tracking (step count, calories burned, active time).
• Continuous heart rate monitoring (at rest, during exercise, and recovery).
• Heart rate variability (HRV) measurement – a key indicator for tracking stress and recovery.
• Detailed sleep analysis: duration, sleep cycles, deep and light phases.
• Recovery and balance indicators to avoid overtraining and improve overall well-being.
• 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 just a connected watch: it is a premium health and performance tracking tool, designed for both active lifestyle enthusiasts and those who wish to gain better insights into their well-being and daily habits.

Comprehensive connectivity

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

• Call management when paired with a compatible smartphone.
• Smart notifications (SMS, emails, and third-party apps).
• Media control to manage music and audio content without reaching for your phone.

All these features are brought together in a clear, streamlined interface, ensuring that the watch remains a practical and fluid tool, rather than an intrusive gadget.
