The cornerstone of a growing collection when it was introduced in 2015, The Carrera Heuer-01 is the signature chrono from TAG Heuer. It brought a new design with skeleton dial, a new in-house movement – the Heuer 01, based on the 1887 – and a new modular case concept whose twelve elements enable multiple combinations of colours and materials. Three new references extend the collection in 2016, including one in ceramic and rubber. Case, bezel, lugs and case middle - all parts which are exposed to friction - are in black ceramic to minimise signs of wear. A textured black rubber strap completes the style. For technical reasons, so as to guarantee water-resistance to 100 metres, steel is present on all the functional parts.
