Designed with professional divers in mind, the Aquaracer Automatic (model CAF2012.BA0815) from TAG Heuer combines state-of-the-art timekeeping technology with sporty, prestige styling. Equipped with calibre 16 automatic movement, this watch winds itself with the natural motion of your wrist and does not require a battery. It features a round blue dial with luminescent hands and markers, a monochrome TAG Heuer logo, and day-and-date calendar at the three o’clock position. Three subdials display 1/10 second, small seconds, and 30-minute registers. A stationary inner bezel, with a seconds ruler, frames the dial, surrounded by a unidirectional rotating outer bezel with a dive time scale and a luminous marker. Set in a 46mm (1.81-inch) brushed steel case that fits comfortably to the contours of your wrist, this watch presents on a handsome and durable steel link bracelet with brushed and polished pieces. The bracelet features an extension system for divers and fastens with a double safety clasp. Other notable features of this watch include a highly scratch-resistant sapphire crystal and a screw-down crown and caseback for water resistance to 300 meters.
