TAG Heuer Carrera Isograph

The Carrera Isograph is an automatic movement from TAG Heuer, introduced in 2020 and currently in production. It is based on the ETA 2892-A2, a widely used Swiss mechanical caliber, and features a carbon-composite hairspring—a lightweight, non-magnetic material that improves resistance to temperature fluctuations and magnetic fields compared to traditional metal hairsprings. This places the Isograph among the more technically differentiated TAG Heuer calibers, though it remains an adapted rather than in-house movement.
