Most smartwatches end up looking like tiny phones strapped to your wrist. TAG Heuer and New Balance's surprise Connected Calibre E5 collaboration doesn’t. This is a luxury watch that just so happens to have smartwatch capabilities.
Here the brand that timed Ayrton Senna meets the brand that paces marathons to create a two-piece crossover built to run. This collab pairs the TAG Heuer Connected Calibre E5 40mm x New Balance Edition watch with the TAG Heuer x New Balance FuelCell SuperComp Elite v5 sneaker, a carbon-plated marathon shoe as tough as its matching timepiece.
The watch looks built as its footwear component. Its 40mm case is black DLC titanium, sandblasted for stealth looks and lightweight feel, with neon green and violet accents lifted straight from the SuperComp Elite’s race-kit palette. Even the strap mirrors the shoe’s mesh upper.
Flip it over and the New Balance logo is engraved on the caseback, a subtle reminder this isn’t a random crossover but a true kit.
Inside the timepiece, TAG dials in for athletes, offering built-in dual-band GPS, heart-rate tracking, and exclusive Running Plans functionality, allowing the wearer to prep their route. The customizable watchfaces riff on classic TAG shapes like the Carrera and Aquaracer, only now they feed in real-time racing splits. TAG timepieces were always functional but never quite like this.
TAG has always blended mechanics and microchips. In 1975, it dropped the Heuer Chronosplit, the first dual-display watch to pair analog hands with a digital LED. Pure ’70s racing energy, built to shave tenths off lap times.
By the 2000s, the Monaco Sixty Nine flipped from mechanical dial to digital screen, another hybrid born for sport. The Connected is just the latest lap, tuned for runners instead of drivers.
The accompanying New Balance shoe pulls the same trick. The FuelCell SuperComp Elite v5 sneaker is New Balance’s sharpest marathon racer yet, shedding weight to just 7.4 ounces in a men’s 9.5. A carbon plate inside a PEBA foam midsole makes every toe-off snappier, giving this quiet powerhouse an innately race-ready feel.
And yet it has the look of a daily driver, clean lines informing a sharp silhouette useful for daily jogs and hardcore record-setting alike.
Game recognize game. 2025 is TAG’s first year as F1’s official timekeeper, meaning that it's responsible for tracking the fastest machines on Earth down to a thousandth of a second. And New Balance's FuelCell SuperComp Elite v5 boosted runner Alex Yee to a record pace at the 2025 London Marathon. One good powerhouse deserves another.
