TAG Heuer Connected Calibre E5
With its latest Connected watch, the Calibre E5, TAG Heuer marks a decade of evolution in luxury smartwatch design. Furthermore, the Swiss maison demonstrates its commitment to merging traditional craftsmanship with modern technology.
The Calibre E5 arrives in two sizes: the signature 45mm and a new 40mm case. Consequently, the collection now appeals to a broader range of wearers. Both versions feature refined case architecture with faceted lugs and reworked pushers. Additionally, a seamless interchangeable strap system eliminates the visual breaks of previous generations.
Materials have been thoughtfully selected throughout. The 45mm models come in stainless steel with ceramic bezels or black DLC-coated titanium. Meanwhile, the 40mm range showcases polished stainless steel with domed sapphire crystals. A rose gold PVD variant adds warmth to the smaller collection, paired with a beige rubber strap.
At its core sits TAG Heuer OS, a proprietary interface developed entirely in-house. The system offers cleaner navigation, improved legibility, and customisable widgets. Moreover, voice calls and voice assistant access are supported through integrated speakers and microphones.
Battery performance has been extended across both sizes. The 45mm model delivers up to three days of use, whilst the 40mm offers two. Notably, just 30 minutes of charging provides a full day’s power for the larger model.
Beyond timekeeping, the Calibre E5 focuses on wellness tracking. The Wellness Activity app monitors movement, calories, and steps with precision. Similarly, the Heart Rate app provides continuous readings with detailed daily insights. Sleep functionality will follow later this winter, analysing sleep phases, blood oxygen saturation, and heart rate variability.
For athletes, the watch introduces structured running plans and dual-band GNSS technology. The Golf Edition features an engraved bezel with hole numbers and a bi-material strap inspired by golf ball dimples. Over 40,000 course maps are available worldwide.
New Balance collab
In tandem with the release of its new Connected, TAG Heuer has partnered with American athletic brand New Balance on a smartwatch designed for serious runners. The collaboration brings together precision, performance and boundary-pushing innovation.
The Connected Calibre E5 40MM x New Balance Edition features a 40mm black DLC-coated Grade-2 titanium case with a sandblasted finish. Moreover, TAG Heuer has developed its user experience and interface in-house, powered by the proprietary TAG Heuer OS. Navigation is more intuitive, with cleaner visuals and optimised performance that deliver a truly seamless digital experience.
The timepiece offers advanced biometric tracking, built-in training plans and seamless post-run analytics. These enhanced wellness capabilities include heart rate monitoring, real-time activity tracking, and an evolving suite of tools designed to support overall well-being. Additionally, the dial includes a newly developed 0 to 100 scale that syncs with app-based training programmes.
The collaboration extends beyond the watch itself. The packaging features a bold, co-designed box with dynamic split design and vibrant green accents, reflecting New Balance’s signature athletic aesthetic. Furthermore, the partnership includes a matching pair of performance running shoes, the TAG Heuer x New Balance FuelCell SC Elite v5 running shoe,
The special-edition pairing targets athletes who train with intention, bridging luxury horology with functional sportswear. It’s a pragmatic fusion rather than mere branding exercise.
