TAG Heuer's latest Connected Calibre E4 in a stunning green

The Swiss luxury watchmaker, a pioneer in the world of connected watches, presents its latest addition to the 45mm E4 line. This exquisite timepiece blends the traditional elegance of watchmaking with the cutting-edge technology of the connected world.


AG Heuer has been at the forefront of connected watchmaking, with the launch of its first TAG Heuer Connected Watch in 2015. These watches seamlessly blend the refinement of traditional timepieces with a digital experience designed for high performance.

This year, TAG Heuer goes a step forward to merge elegance with sports, embracing the ever-popular and sumptuous green color in the newest TAG Heuer Connected Calibre E4 with a deep and understated green shade that exudes sophistication. This alluring timepiece is designed to captivate trendsetting connected watch enthusiasts, offering a versatile and distinctive choice for everyday wear.

The TAG Heuer Connected Watch features a robust steel case in a 45 mm size. What sets this watch apart is the striking green ceramic polished bezel, perfectly complemented by a matching green rubber strap. TAG Heuer has expertly blended these elements to create a harmonious and visually captivating ensemble.

In terms of the product itself, the Calibre E4 remains true to its roots, featuring the standard steel case with a black-coated steel crown. For this watch, TAG Heuer offers three distinct watch faces, named Mirage, Prism, and Chromatic. These watch faces have been meticulously adorned with the different hues of green that mirror the bezel, offering a touch of animation without compromising on elegance. These watch faces have been designed to be applied to other regular E4 watches, extending the elegance onto everyone’s wrists.

Highlighting the versatility of the watch faces, TAG Heuer provides over 20 options. With thousands of possible combinations, TAG Heuer’s craftsmanship combines with the flexibility to match everyone’s style and look. The watch blends seamlessly into all aspects of the wearer’s life, either by keeping themselves connected during the working hours or recording their fitness sessions, while also tracking their daily activities. Both men and women will benefit from the impressive offering of the TAG Heuer Connected’s digital services and custom apps.

With the TAG Heuer Wellness app, the smart timepiece delves into the realms of wellness and performance, offering users a comprehensive overview of health metrics by monitoring live heart rate, daily step goals and burned calories.

The watch also seamlessly integrates with an active lifestyle using the TAG Heuer Sports app. From running and cycling to walking, swimming and various activities, the watch ensures precise sports tracking. It even includes the seven-minute workout with guided coaching directly on the watch. For enthusiasts of running and hiking in the mountains, the app provides precise altitude tracking, allowing wearers to review their pace and assess how the altitude impacts their performance.

And, of course, Golf aficionados can fully immerse themselves in the course with TAG Heuer Golf. The watch autonomously tracks shots from tee to green, intelligently refining club statistics over time. This allows players to focus solely on their shot, embracing the pure spirit of golf.

This elegant timepiece comes as an addition to the black and blue options available in the 45mm E4 series, expanding the range to cater to diverse tastes and preferences. As we step into the future of horology, TAG Heuer continues to set the standard for luxury and innovation. The TAG Heuer Connected Calibre E4 in green epitomises the brand’s commitment to blending tradition with technology, offering a connected watch that is not only ideal for sports but also increasingly elegant and wearable for everyday life.
