In 2019, Tag Heuer celebrates its fourth consecutive year as official timekeeper of the London Marathon, with its #DontCrackUnderPressure slogan inspiring participants to push through the 26.2-mile course. The brand’s ethos of endurance, focus and precision is shared with runners, and Tag Heuer ensures the most precise calculations of marathon times. The watchmaker will also send a text message to competitors containing their official time when they cross the  finish line.
