Tag Heuer Connected Calibre E4 Review

As I laced up my running shoes and strapped the Tag Heuer Connected Calibre E4 to my wrist, I couldn’t help but feel a surge of excitement. This wasn’t just any smartwatch – it was a luxury timepiece that promised to elevate my workout experience. As I set off on my morning jog, the E4’s vibrant display came to life, tracking my pace and heart rate with precision. The TAG Heuer smartwatch felt substantial yet comfortable, a reminder of its premium pedigree. It’s not often that a device bridges the gap between high-end horology and cutting-edge technology so seamlessly.

The significance of the Tag Heuer Connected Calibre E4 in the watch world can’t be overstated. It represents TAG Heuer’s commitment to innovation while maintaining its luxury heritage. This isn’t just a smartwatch; it’s a statement piece that belongs in the same conversation as traditional luxury timepieces. The E4 stands out in the smartwatch category by offering a level of craftsmanship and attention to detail that’s typically reserved for mechanical watches.

As I continued my run, I couldn’t help but wonder: how does the Tag Heuer Connected Calibre E4 stack up against other luxury smartwatches in terms of performance and style? Let’s dive deeper into its features and design to find out.

Features & Design

The Tag Heuer Connected Calibre E4 is a marvel of modern watchmaking, blending traditional luxury with cutting-edge technology. At its heart lies a powerful processor that ensures smooth performance across all apps and features. This isn’t just about speed; it’s about providing a seamless user experience that matches the watch’s premium status.

One of the standout features of the E4 is its stunning OLED display. With a resolution of 454 x 454 pixels, it offers crisp, vibrant visuals that are easily readable even under bright sunlight. This high-quality display isn’t just for show – it enhances the functionality of every feature, from fitness tracking to notifications.

Speaking of fitness tracking, the E4 takes this to another level. It’s equipped with an array of sensors including an accelerometer, gyroscope, heart rate monitor, and GPS. These work in tandem to provide accurate data on a wide range of activities. Whether you’re running, cycling, or swimming, the E4 captures detailed metrics to help you improve your performance.

The E4 battery life is impressive for a smartwatch of this caliber. It can last up to a day with normal use, including workout tracking and always-on display. For those longer adventures, there’s a battery-saving mode that can extend the life up to 5 days while still providing basic time and activity tracking.

Design-wise, the Tag Heuer Connected Calibre E4 is a testament to TAG Heuer’s expertise in crafting luxury timepieces. The 45mm case is made from sandblasted titanium, striking a perfect balance between durability and lightweight comfort. The sapphire crystal face offers superior scratch resistance, protecting the beautiful display beneath.

The rotating crown isn’t just an aesthetic nod to traditional watches; it’s a functional element that allows for easy navigation through the watch’s interface. This thoughtful design choice showcases TAG Heuer’s commitment to blending classic watchmaking elements with modern smartwatch functionality.

Customization is a key aspect of the E4’s design philosophy. The watch faces are incredibly detailed, mimicking the look of TAG Heuer’s mechanical watches down to the smallest details. You can even add complications to these faces, allowing you to see relevant information at a glance.

Water resistance is a crucial feature for any sports watch, and the E4 doesn’t disappoint. With a water resistance rating of 5 ATM, it can withstand depths of up to 50 meters. This means you can confidently wear it while swimming or in the shower without worry.

The strap options further enhance the E4’s versatility. From sporty rubber straps perfect for workouts to elegant leather options for more formal occasions, there’s a strap to suit every style and situation. The quick-release system makes it easy to switch between straps, allowing the E4 to adapt to your changing needs throughout the day.

On the software side, the E4 runs on Wear OS by Google, providing access to a wide range of apps and services. The integration with Google services is seamless, allowing you to use Google Pay for contactless payments, Google Maps for navigation, and Google Assistant for voice commands.

One unique feature that sets the E4 apart is its golf-specific functionality. Developed in collaboration with professional golfers, it offers detailed course maps, shot tracking, and score keeping. This level of specialized functionality showcases TAG Heuer’s commitment to creating a smartwatch that goes beyond the basics.

Pro’s & Cons

The Tag Heuer Connected Calibre E4 offers a compelling blend of luxury and technology, but like any device, it has its strengths and weaknesses. Let’s examine these in detail to provide a balanced view of this premium smartwatch.


  • Exceptional build quality with premium materials
  • Stunning OLED display with high resolution
  • Comprehensive fitness tracking capabilities
  • Elegant design that looks and feels like a luxury watch
  • Customizable watch faces with intricate details
  • Water-resistant to 50 meters
  • Specialized features like golf tracking
  • Smooth performance thanks to powerful processor
  • Good battery life with power-saving options

Despite these impressive features, there are some aspects of the E4 that might not appeal to everyone. Let’s look at some of the potential drawbacks.


  • High price point compared to other smartwatches
  • Large 45mm case may be too big for some wrists
  • Battery life, while good, still requires daily charging for full smartwatch use
  • Limited watch face options compared to some competitors
  • Wear OS can be less intuitive than some other smartwatch operating systems

Comparable alternatives to the Tag Heuer Connected Calibre E4

While the Tag Heuer Connected Calibre E4 stands out in the luxury smartwatch market, it’s worth comparing it to other high-end options. The Apple Watch Series 7 is a popular alternative, offering a sleek design and seamless integration with iOS devices. The Apple Watch provides a more extensive app ecosystem and arguably more intuitive interface. However, it lacks the traditional watch aesthetics and luxury brand appeal of the E4. The Apple Watch’s battery life is comparable, but it doesn’t offer the same level of water resistance or specialized features like the E4’s golf tracking.

On the other hand, the Garmin Forerunner 945 caters more to serious athletes. It offers more comprehensive fitness tracking features and significantly longer battery life – up to two weeks in smartwatch mode. However, it sacrifices the luxury look and feel of the E4, opting for a more utilitarian design. The Forerunner 945 also lacks the premium materials and customizable watch faces that make the E4 stand out. While it may be a better choice for hardcore fitness enthusiasts, it doesn’t offer the same versatility for transitioning from workout to formal wear.

Tag Heuer Connected Calibre E4 Value & Availability

The Tag Heuer Connected Calibre E4 comes with a premium price tag, reflecting its position as a luxury smartwatch. While it’s significantly more expensive than many mainstream smartwatches, it offers a level of craftsmanship and brand prestige that justifies the cost for many watch enthusiasts. The E4 is widely available through TAG Heuer’s official website, authorized dealers, and select high-end retailers. Its availability may vary depending on specific models and configurations. While it’s not an investment piece in the traditional sense of mechanical watches, the E4 offers value through its blend of luxury aesthetics and advanced technology, making it a unique proposition in the smartwatch market.
