The sale of the collection was timed to coincide with the 150th anniversary of TAG Heuer, that now belongs to the luxury conglomerate LVMH. Several of the pieces were bought by the brand for the TAG Heuer museum in La Chaux-de-Fonds, including a rare 'Chronomatic' Carrera. The sale offered the chance for collectors to purchase iconic models from this house known for its association with the world of racing. A special edition of the Silverstone Calibre 11 chronograph was made for the auction. The signature of the Honorary Chairman Jack Heuer, who designed the original Silverstone in 1974, appears on the red dial. The watch sold for £10,000 and the proceeds were donated to the charity Green Cross International.
