IWC Aquatimer Chronograph 42 IW371903 Titanium

The IWC Aquatimer Chronograph 42 Titanium with reference IW371903 is a sporty diving watch that combines uncompromising functionality with IWC's signature engineering. The 42 mm case and matching titanium bracelet impress with their low weight, high resistance, and comfortable wearability. The striking black dial with luminous hands and markers ensures excellent readability even in low light conditions, while the internal rotating bezel is operated safely and precisely via the second screw-down crown.

Inside, the reliable IWC Calibre 79320 operates with automatic winding and a power reserve of around 44 hours. In addition to precise timekeeping, the watch features a chronograph function as well as a combined day-date display. The scratch-resistant sapphire crystal reliably protects the dial, while the screw-down crown and water resistance up to 10 bar (100 meters) make the Aquatimer a robust companion for everyday wear and water sports.

With its characteristic combination of technical design, high-quality titanium, and sporty elegance, the IWC Aquatimer Chronograph IW371903 is one of the sought-after models from the early Aquatimer generation. It combines the robustness of a professional diving watch with the precision of a Swiss chronograph and is an excellent choice for both active wearers and collectors of classic IWC sports models.
