The 40mm case and bold dial of this TAG Heuer Aquaracer make it an essential ally in your achievement, a heavy-duty diver that is both extremely technical, and offers a style that stands out. It is a tool that can endure any conditions Last year, TAG Heuer breathed new life into the Aquaracer story with the Aquaracer Professional 300, the brand\'s ultimate luxury diver\'s watch. That story began in 1978 when Jack Heuer introduced the Heuer Reference 844. Designed for men and women who loved outdoor sports and adventures in nature, on land or in the water, the watch defined a new high-performance category of versatile wristwatches that could be relied on in extreme conditions. The Aquaracer name was added in 2004 and continued the legacy of the family\'s six design codes: a uni-directional rotating bezel; a screw-down crown; water resistance to at least 200 metres; luminous markings; a sapphire crystal; and a double safety clasp. Hot on the heels of the Aquaracer Professional 300 comes the Aquaracer Professional 200, a sister model designed to be as comfortable speed flying or ice skiing as it is pounding the pavement. Like the larger 43mm Aquaracer Professional 300, it too picks up on those six design codes established more than forty years ago. At every turn, the new watches are about refinement. The larger of the two models that debut today is 40mm across and 11mm thick, giving a sleeker silhouette and a slenderer profile compared to the outgoing model it replaces, which was 41mm in diameter and 12mm thick. TAG Heuer\'s design and engineering teams have delivered a watch consistent with the Aquaracer\'s fundamental principles, only with greater sophistication and even more durability.
