IWC Aquatimer Chronograph Ref. IW376803 – 42mm Stainless Steel with Black Dial on Black Rubber Strap

Purpose-built for precision under pressure, the IWC Aquatimer Chronograph 42mm in stainless steel with a black dial exemplifies IWC’s mastery of professional diver’s watchmaking. Rugged yet refined, this timepiece merges technical innovation with a timeless aesthetic, engineered for explorers who demand reliability at depth and elegance on land.

The stainless steel case projects strength and purpose, complemented by IWC’s patented SafeDive internal/external rotating bezel, designed for secure and accurate dive-time measurement. The black dial balances clarity and complexity, featuring luminous hands, bold indexes, and a tri-compax chronograph layout that includes 12-hour, 30-minute, and small-seconds subdials. A day-date display at 3 o’clock adds practical functionality to its professional instrument design.

At its heart beats the IWC Calibre 79320 automatic chronograph movement, offering a 44-hour power reserve and the precision expected of the Schaffhausen manufacture. The black rubber strap, durable and comfortable, adapts seamlessly from sea to shore.

Water-resistant to 300 meters, the Aquatimer Chronograph stands as an icon of endurance — a perfect balance of technical capability, sport-driven design, and IWC’s legacy of fine Swiss watchmaking.
