Swiss luxury watchmaker TAG Heuer has officially lifted the covers off the Connected Calibre E5, which comes with improved features and even a stunning New Balance collaboration. The fifth generation of its pioneering connected timepiece collection is the brand’s most refined expression of its Avant-Garde philosophy to date.
For over a decade, TAG Heuer has redefined what a smartwatch can be. Fusing innovation with craftsmanship and emotion, the timepiece is redefined through the lens of traditional Swiss watchmaking.
The Calibre E5 serves as the next exciting chapter of the model, which continues to embody a digital heart and a mechanical soul. Designed for those who navigate modern life with intention, it offers a seamless blend of physical artistry and intelligent technology, uniting the realms of performance and personal expression.
Refined And Robust
Available in the signature 45mm size and now a new, smaller 40mm case, the Calibre E5 offers a tailored fit for every wrist. Each detail has been meticulously considered, including reworked pushers and sharper faceted lugs to an updated strap integration system that enhances both comfort and aesthetic harmony.
Materials are equally sophisticated. Stainless steel and black DLC-coated titanium define the 45mm models, while the 40mm variant introduces a polished stainless-steel case with domed sapphire crystal and a warm rose golden PVD option. The new interchangeable strap system allows for effortless personalisation, with options in rubber, leather, metal and high-performance textiles.
Paired with the most comprehensive collection of digital watch faces ever developed by TAG Heuer, including designs inspired by the Carrera, Aquaracer and Formula 1 lines, the Calibre E5 offers both heritage and innovation on the wrist.
Digital Heart
At its core is TAG Heuer OS, a proprietary operating system crafted entirely in-house to deliver a seamless digital experience. This latest version offers cleaner visuals, improved legibility and intuitive navigation, all enhanced by custom TAG Heuer haptics and audio design. Activity tracking, heart rate monitoring, and wellness insights are integrated with ease, while extended battery life (up to three days for the 45mm model and two for the 40mm) ensures the watch is ready for whatever lies ahead.
TAG Heuer x New Balance
From refined design to performance-driven functionality, the TAG Heuer Connected Calibre E5 is a statement of modern luxury, built not just to measure time, but to support wellbeing, ambition, and movement with purpose. And now comes with a stunning new collaboration.
Expanding its commitment to performance and lifestyle, TAG Heuer has dropped a unique collaboration with New Balance. Best yet, the TAG Heuer Connected Calibre E5 40mm x New Balance Edition smartwatch, arrives alongside the New Balance FuelCell SC Elite v5 running shoe.
Together, they form a dual release designed for runners who demand precision, power and style for both the wrist and the track. Crafted in ultra-lightweight black DLC-coated Grade 2 titanium, the 40mm New Balance Edition features a deep English Purple hue inspired by elite athletic performance.
The dial introduces a newly developed 0–100 performance scale, complemented by an engraved New Balance logo on the caseback. The patented Cushion Comfort System strap blends a flexible rubber base with a high-tech textile overlay, paired with an additional stretch textile strap embroidered with the New Balance emblem.
For Active Types
Powered by the next-generation TAG Heuer OS and Qualcomm Snapdragon 5100+ chipset, the watch supports advanced wellness tracking, dual-band GPS, extended battery life, and six exclusive New Balance running plans.
Included are guided sessions, real-time pace feedback, and automatic sync to the TAG Heuer Connected app. Each designed to enable athletes to train smarter and track progress with precision. Exclusive purple and grey watch faces, Casual, Balance, and Reskin, complete the experience.
The collaboration continues with the release of the New Balance FuelCell SC Elite v5, a performance running shoe featuring a co-branded engineered mesh upper, FuelCell midsole with carbon fibre plate, and an ultra-responsive PEBA cushioning system. Together, the watch and the shoe deliver a lifestyle-meets-performance proposition for those pushing boundaries on every front.
