The TAG Heuer Carrera Chronograph Tourbillon 45mm (Ref. CAR5A90) is a high-end luxury Swiss watch that combines two of horology's most prestigious complications: a one-minute flying tourbillon and a column-wheel chronograph. It is celebrated in the watch community for making the tourbillon complication accessible at a disruptive price point relative to traditional haute horlogerie brands.

  The dial is completely open-worked (skeletonized) with a vertical brushed finish, offering a techno-industrial view of the gear train and mainspring barrel. Silver-toned sub-dials sit at 3 o'clock (30-minute counter) and 9 o'clock (12-hour counter).

  The defining feature is the prominent flying tourbillon window at 6 o’clock. Because it lacks an upper bridge, the regulating organ appears to float freely. The movement operates at a high-beat frequency of 4 Hz (28,800 vibrations per hour) and holds an official chronometer certification from the Swiss Official Chronometer Testing Institute (COSC).
