TAG Heuer Connected Calibre E5 Running Edition: Built for the NYC Marathon

Timing the Five Boroughs

TAG Heuer returns for a second consecutive year as Official Timekeeper of the TCS New York City Marathon. To mark the partnership, the Swiss watchmaker introduces the Connected Calibre E5 Running Edition, a 45mm smartwatch developed specifically with runners and endurance athletes in mind. It combines a lightweight case made from titanium grade 2 with dedicated running functions and a stretch strap designed for an active fit. This is the third sport-specific model of the Connected TAG Heuer has launched this year, in June introducing the Connected Calibre E5 Golf Watch in collaboration with TaylorMade, and before that introducing the Connected Calibre E5 x Formula 1 Edition in February. 

TAG Heuer’s role at the event extends beyond the watch itself. During race week, the brand will provide the official countdown clock at the TCS New York City Marathon Expo, as well as branded clocks at the start, along the course and at the finish line. The partnership also encompasses two additional New York Road Runners events, the United Airlines NYC Half and the Abbott Dash to the Finish Line 5K. The 2026 TCS New York City Marathon marks 50 years since the race expanded beyond Central Park to its current five-borough course in 1976, while the event itself dates back to 1970.

Designed For Running

The Connected Calibre E5 Running Edition builds on TAG Heuer’s fifth-generation Connected platform and runs on TAG Heuer OS. Its case features integrated pushers and a non-linear running-scale bezel reinforcing its athletic character. A PPG heart-rate sensor provides continuous heart-rate tracking, while the ergonomic stretch strap is designed to remain comfortable during longer runs and training sessions. The watch is priced at $2,400.

Dedicated to New York 

The marathon partnership also brings two dedicated digital watch faces to the Connected E5 collection, developed in collaboration with New York Road Runners. The Timekeeping X NYRR display takes a minimalist approach, with large orange hour, minute and seconds indications against a dark textured background and the TCS New York City Marathon emblem.

The TRKR x NYRR watch face is geared toward runners, combining a central digital time display with data including the day, date, step count, calories burned and ambient information. Both designs will be available across the core Connected E5 models through the TAG Heuer Connected app.
