TAG Heuer Connected Calibre E5 – 45 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 another step forward in the meeting 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 object, but as a true watchmaking instrument, carrying heritage, style, and performance.
Every detail – from the case design to the ergonomics of the interface – reflects this commitment to creating a watch that appeals both to mechanical watch enthusiasts and to those seeking connectivity and sports performance.

The fifth-generation Calibre E5 goes beyond simply adding new functions: it reinvents the user experience, with a redesigned interface, smoother navigation, and enhanced performance, while preserving the aesthetics and finishing quality that define TAG Heuer.

In this 45 mm steel version with a steel bracelet, the Connected Calibre E5 embodies TAG Heuer’s watchmaking DNA more than ever: a sporty yet elegant spirit, designed to accompany its wearer from everyday life to the most demanding activities.

Design & Hardware

The TAG Heuer Connected Calibre E5 – 45 mm in steel with steel bracelet exemplifies the fusion of Swiss watchmaking savoir-faire and cutting-edge connected innovations.
It draws on the aesthetic codes of TAG Heuer’s iconic mechanical collections – sharp lines, dynamic profiles, and refined finishes – affirming its identity as a true 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: sharp lines, refined finishes, and proven durability.
The polished black ceramic bezel, engraved with silver markers, evokes the world of sports chronographs and is remarkably scratch-resistant.
The crown, adorned with the TAG Heuer logo, allows smooth and precise handling, even in motion.
The two redesigned side pushers, offering improved grip and a crisper click, provide quick access to essential functions and strengthen the link with mechanical chronograph design language.
The entire watch is protected by a flat sapphire crystal, ensuring readability and long-term durability.
With 50-meter water resistance, the watch is ready to face the challenges of everyday life as well as outdoor activities.

Readability and comfort

The 454 × 454 px AMOLED HD display, bright and high-contrast, faithfully reproduces the details of digital dials, delivering deep blacks and vivid colors.
The adaptive brightness automatically adjusts intensity for perfect visibility, whether in bright sunlight or low-light conditions.
The stainless steel H-link bracelet, both robust and refined, gives the watch a more urban and sophisticated character without compromising on wrist comfort.
Thanks to TAG Heuer’s quick-change system, it can be easily swapped for a leather or rubber strap, allowing a seamless transition from an urban look to a sportier style.

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 areas, forests, or mountainous regions.
• Advanced biometric sensors for accurate monitoring of performance and health:
  • Next-generation optical heart rate sensor (PPG), enhanced for more stable and precise measurements.
  • SpO₂ sensor to measure blood oxygen saturation.
  • HRV (heart rate variability) tracking for stress and recovery analysis.
  • Sleep tracking with analysis of rest phases.
  • Barometric altimeter for recording elevation changes.
  • Compass and gyroscope for orientation and stability during movement.

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

Battery life and charging

Optimized energy management allows the watch to run for up to 2 days in regular use and up to 3 days in Low Power mode.
The fast-charging system is designed to keep pace with active lifestyles:

• 30 minutes are enough to recover approximately 1 day of use,
• a full charge is achieved in just 90 minutes.

Watch Experience & Software

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

Redesigned TAG Heuer OS

The fifth-generation Calibre E5 debuts a completely reimagined version of TAG Heuer OS, developed in-house by the brand.
The interface is smoother, more responsive, and more intuitive, thanks 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 use on the wrist.
• Improved responsiveness when launching apps or tracking sports activities.

Customization and watch faces

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

• Customizable complications: users can display key information such as battery level, heart rate, weather, and sports progress directly on the 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 various disciplines: running, cycling, swimming, hiking, golf, and training.
• Real-time metrics: distance, pace, speed, elevation gain, and heart rate zones integrated into each activity.
• Use of dual-band GNSS for precise route tracking, even in complex environments.
• Direct integration with the TAG Heuer Sports app to review history, compare performance, and adjust training.

For daily wellness and health:

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

• Daily activity tracking (step count, calories burned, active time).
• Continuous heart rate monitoring (resting, 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 prevent overtraining and improve quality of life.
• Progress charts 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 just a connected watch: it is a premium health and performance tracking tool, designed for fitness enthusiasts as well as those who want better insights into 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,
• Smart notifications,
• Media control for managing music and audio content without taking out your phone.

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