As Official Timekeeper of Formula 1 from 2025, TAG Heuer provides the proprietary timing infrastructure that measures every race, qualifying session, and practice lap across the 24-race Grand Prix calendar. The system delivers millisecond-accurate measurements that determine sporting outcomes and are integrated into all broadcast graphics carrying the TAG Heuer name. The timing infrastructure is not a retail product but a commercial and functional asset central to the LVMH-Formula 1 partnership.
