The IWC Aquatimer Chronograph IW376803 takes the line's instrument-first design into a 44mm stainless steel case with a black dial and matching rubber strap. Its monochrome layout keeps the watch straightforward and functional, while the 17mm case gives it real presence on the wrist. The automatic movement combines a chronograph with a calendar for daily use. From 2021, it reads as a modern sports chronograph with IWC's clean, direct style.
