TAG Heuer Aquaracer 300M Chronograph Ref. CAY211A.BA0927

The 2019 TAG Heuer Aquaracer 300M Chronograph, reference CAY211A.BA0927, is a striking instrument for professional water sports enthusiasts and lovers of robust Swiss chronographs. With its powerful 43 mm stainless steel case, distinctive black ceramic bezel, and dial featuring a signature horizontal striped pattern, this model carries forward the brand’s rich maritime heritage, which dates back to Heuer’s first water-resistant pocket watches in 1895. Equipped with the extremely reliable Calibre 16 automatic movement, reference CAY211A combines uncompromising functionality with a modern, masculine aesthetic.

• Impressive 43 mm stainless steel case: Crafted from finely brushed and polished 316L stainless steel. The case stands out with its distinctive angular lines and offers a striking presence on the wrist with familiar ergonomics.

• Scratch-resistant unidirectional rotating Ceramic bezel: The twelve-sided diver’s bezel features a high-strength black Ceramic insert. It has engraved 60-minute graduations and the six signature riders of the Aquaracer series for optimal grip, even when wearing diving gloves.

• Deep black dial with horizontal striped pattern: The dial features the iconic Aquaracer ribbed pattern, reminiscent of ship decks. Generously sized applied indices and hands are coated with Super-LumiNova® to ensure excellent legibility in deep water or in the dark.

• Three-register Chronograph layout: The classic subdial arrangement features a 30-minute counter at 12 o’clock, a 12-hour counter at 6 o’clock, and Small Seconds at 9 o’clock. Yellow accents on the Chronograph hands and model name add sporty contrast.

• Proven TAG Heuer Calibre 16 automatic movement: Inside beats the extremely robust and easy-to-service Calibre 16 (based on the legendary Valjoux 7750 / Sellita SW500). It operates at a frequency of 28,800 vibrations per hour (4 Hz) and offers a power reserve of approximately 42 hours.

• Scratch-resistant Sapphire Crystal with Cyclops magnifier: Protected by an anti-reflective Sapphire Crystal with an integrated magnifying lens over the date display at the 3 o’clock position.

• Professional water resistance (300 m / 30 ATM): The screw-down stainless steel crown with two O-ring seals, push-button Chronograph pushers, and solid screw-down case back ensure the case is sealed for professional diving depths.

• Embossed diver’s helmet case back: The stainless steel case back features the traditional, detailed engraving of the historic diver’s helmet (Diver's Helmet) as a mark of quality and origin.

• Three-row stainless steel bracelet with diving extension (Ref. BA0927): The watch is worn on a satin-finished three-row stainless steel link bracelet. The stainless steel folding clasp features double safety push-buttons and an integrated diving extension.

• The ultimate all-round tool watch Chronograph (2019): Reference CAY211A.BA0927 represents hard-wearing Swiss engineering: a robust, versatile Chronograph that performs just as well in extreme underwater conditions as it does in active everyday life.
