TAG Heuer Connected Calibre E5 – 40 mm – Steel – Steel bracelet

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 blending watchmaking emotion and digital innovation.

Guided by its philosophy “Emotion Beyond Technology”, TAG Heuer does not see the connected watch as just a high-tech gadget, but as a true horological instrument, carrying heritage, style, and performance.
Every detail – from the case design to the ergonomics of the interface – reflects the brand’s ambition to create a watch that appeals to mechanical watch enthusiasts as much as to those seeking advanced connectivity and sports performance.

The fifth-generation Calibre E5 goes beyond adding features: it reinvents the user experience with a redesigned interface, smoother navigation, and enhanced performance, all while retaining the distinctive aesthetics and finishing quality of TAG Heuer.

In this 40 mm stainless steel version with a steel bracelet, the Connected Calibre E5 captures TAG Heuer’s watchmaking DNA in a more refined and versatile format.
More compact and lightweight, it is designed to fit all wrists and accompany its wearer with the same precision and reliability, from daily life to sports activities, while delivering timeless urban elegance.

Design & Hardware

The TAG Heuer Connected Calibre E5 – 40 mm in stainless steel with a steel bracelet represents the perfect fusion of Swiss watchmaking expertise and the latest connected innovations.
It adopts a cleaner, more elegant style without compromising the robustness and precision that define the Maison.
This 40 mm format makes it particularly suitable for slimmer wrists and for those seeking the perfect balance between sportiness and sophistication.

A case inspired by traditional watchmaking

The polished and brushed 40 mm stainless steel case reflects TAG Heuer’s expertise in creating durable and refined sports watches: sharp lines, meticulous finishing, and proven robustness.
The absence of a separate bezel enhances the sleek design and highlights the domed sapphire crystal, which ensures excellent legibility and long-lasting scratch resistance.
The crown, adorned with the TAG Heuer logo, allows for smooth and precise handling, even on the move.
The two side pushers, redesigned for better grip and a more tactile click, provide intuitive access to essential functions while reinforcing the connection to the chronograph heritage.
With water resistance up to 50 meters, the watch is ready to face daily challenges as well as outdoor activities.

Readability and comfort

The 390 × 390 px HD AMOLED display is bright and highly contrasted, faithfully reproducing the details of the digital watchfaces with deep blacks and vivid colors.
Adaptive brightness automatically adjusts the intensity for optimal visibility, whether in bright sunlight or low-light conditions.
The stainless steel H-link bracelet combines durability and refined aesthetics, making the watch suitable for both urban and professional environments without compromising comfort.
The TAG Heuer quick-release system allows easy strap changes, enabling a seamless transition from an urban look to a sportier style with a leather or rubber strap.

Technological core

Beneath its refined watchmaking exterior lies a cutting-edge technological engine:

• Qualcomm Snapdragon 5100+ processor: ensures smooth and responsive navigation while optimizing energy consumption.
• Dual-band GNSS (L1 + L5): delivers ultra-precise GPS tracking, even in dense urban environments, forests, or mountainous terrain.
• Advanced biometric sensors for precise performance and wellness tracking:
  • Next-generation optical heart rate (PPG) sensor – improved for more stable and accurate readings,
  • SpO₂ sensor to measure blood oxygen levels,
  • HRV (Heart Rate Variability) tracking for stress and recovery analysis,
  • Sleep monitoring with detailed phase analysis,
  • Barometric altimeter for recording elevation changes,
  • Compass and gyroscope for orientation and stability in motion.

This combination transforms the watch into a true performance companion, delivering precise data for athletes as well as for everyday wellness monitoring.

Battery life and charging

Optimized energy management provides up to 1.5 days of full usage and up to 2 days in Low Power mode.
Fast charging ensures you are never slowed down:

• 40 minutes to recover approximately one full day of power,
• full charge achieved in just 90 minutes.

Watch Experience & Software

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

Redesigned TAG Heuer OS

The fifth-generation Calibre E5 introduces a completely re-engineered 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.

• Seamless navigation: faster transitions between apps and watchfaces,
• Simplified, more visual menus designed for intuitive use on the wrist,
• Enhanced responsiveness when launching apps or tracking sports activities.

Customization and watchfaces

The watchmaking spirit of TAG Heuer shines through in a curated collection of exclusive digital watchfaces.
These faces draw inspiration from the iconic Carrera, Monaco, and Aquaracer chronographs, showcasing the same attention to detail and finishing.

• Customizable complications: users can display the most relevant information (battery level, heart rate, weather, training progress, etc.) directly on their chosen watchface.

Sport, Outdoor & 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 accurate and actionable data.

For sport 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,
• High-precision route tracking thanks to dual-band GNSS, even in challenging environments,
• Direct integration with the TAG Heuer Sports app to review history, compare performances, and optimize training.

For wellness and daily health:

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

• Daily activity tracking (steps, calories burned, active time),
• Continuous heart rate monitoring (resting, active, and recovery phases),
• HRV measurements for stress and recovery assessment,
• Detailed sleep analysis: duration, cycles, deep and light phases,
• Recovery and balance indicators to avoid overtraining and promote overall well-being,
• Progress charts and personalized goals, accessible directly on the watch or via the TAG Heuer Wellness app.

This complete ecosystem makes the Calibre E5 much more than a connected watch: it is a premium health and performance tracking tool designed for regular sports enthusiasts and for those wishing to better understand their condition and daily habits.

Comprehensive connectivity

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

• Call management when paired with a compatible smartphone,
• Notifications,
• Media control to manage music and audio content without taking out the phone.

All these functions are grouped into a clear interface, ensuring the watch remains a practical and fluid tool without becoming an intrusive gadget.
