TAG Heuer’s Connected Calibre E5 Marks the Rhythm of New York
As Official Timekeeper of the TCS New York City Marathon, TAG Heuer synchronises precision engineering with the pulse of one of the world's most demanding endurance events. The new Connected Calibre E5 Running Edition 45mm becomes the instrument through which runners measure their performance across the city's five boroughs.

The marathon represents a singular convergence of human endeavour and mechanical precision, where each heartbeat, each stride and each increment of distance becomes a narrative written across the urban landscape. For half a century, the TCS New York City Marathon has commanded this stage, drawing together athletes from across the globe to test their mettle against themselves and one another. TAG Heuer, entrusted as the Official Timekeeper, understands that in such moments, the instrument on the wrist becomes something far more consequential than a mere accessory to tell the time.
The new Connected Calibre E5 Running Edition has been conceived with this exacting context in mind. Measuring 45mm across the case, the smartwatch distils the watchmaker’s expertise into a device engineered to capture those metrics that illuminate performance: pace and distance, certainly, but also stride and recovery, those finer gradations that separate adequate effort from excellence. The data flows in real time, offering the runner an intimate understanding of their biomechanics and endurance as the miles unfold.
Two distinct digital watchfaces, developed in collaboration with New York Road Runners, commemorate fifty years of this storied marathon. These faces serve as more than mere aesthetics; they anchor the wearer to the occasion, to the community of runners gathering across the five boroughs, to the collective endeavour that defines this event. They speak to the particularity of this moment, this place, this gathering.
The Rhythm of Race Day
TAG Heuer’s relationship with precision timing extends back through decades of horological achievement, and this partnership with the marathon represents a natural extension of that philosophy. From the starting line to the finish, the watchmaker sets the tempo, ensuring that every split time, every intermediate checkpoint, every moment of the unfolding drama is captured with the fidelity and accuracy that only a master horologist can deliver.
The Connected Calibre E5 Running Edition embodies TAG Heuer’s conviction that technology and tradition need not exist in tension. The smartwatch integrates contemporary connectivity with the Swiss watchmaker’s enduring commitment to precision engineering. It is a tool designed not merely to accompany the athlete, but to enhance their understanding of themselves in motion.
In the hours before the starting pistol sounds, as runners across New York conduct their final preparations, the Connected Calibre E5 becomes a companion to their ambition, a keeper of the metrics that will, in aggregate, tell the story of their marathon. TAG Heuer, as Official Timekeeper, ensures that no second passes unmeasured, that every moment of the race unfolds within the framework of metronomic precision that only a storied Swiss manufacture can provide.
