About the Aquaracer family
The Aquaracer was introduced in the early 2000s as TAG Heuer's main dive watch line, following earlier Heuer and TAG Heuer divers such as the 1000 and 2000 series. Its case has a unidirectional rotating bezel, often with distinctive tabs at the edges, and water resistance of 300 metres or more on most models.
The catalog includes a very wide range of quartz and automatic models, with calibers such as Caliber 5 and Caliber 7 GMT, chronographs with Caliber 16 and 45, and cases in steel, titanium, ceramic and DLC-coated steel. Dealers identify a piece by its full reference, which records size, movement and dial, and check the bracelet and bezel.
