The case is 41 mm in diameter, water-resistant to 100 meters, and features brushed and polished surfaces and a thin, polished bezel. The curved, scratch-resistant sapphire crystal is treated with nonreflective coating on both sides; another sapphire window in the caseback displays Calibre 8, an automatic movement with 42-hour power reserve, rapid date correction function, and a rotor decorated with côtes de Genève. The TAG Heuer Calibre 8 movement — which consists of an ETA 2892-A2 base and a Soprod TT651 module that powers both the big date and GMT displays — is also a COSC-certified chronometer.
Six versions of the TAG Heuer Carrera Calibre 8 Grande Date GMT are available, all pictured below: dial options are black, silver and anthracite (the later two have a sunray pattern), each paired with either a matching-color alligator leather strap (except the silver dial, paired with a brown strap) or with the so-called Grand Carrera stainless steel bracelet, with three rows of links bearing alternating polished and brush-finished surfaces. The dials all have polished, hand-applied faceted indices and polished hour and minute hands, all with luminescent material, as well as a hand-applied TAG Heuer “shield” logo at 3 o’clock.
