Overview
The IWC Aquatimer Chronograph reference IW376803 combines the brand's long-running diver line with integrated chronograph functionality in a 44 mm stainless steel case. Its black dial and purpose-built architecture reflect the Aquatimer collection's commitment to legibility and underwater utility. Calibre 79320 provides the movement foundation, delivering reliable timekeeping and elapsed-time measurement in a single package.
History
IWC introduced the modern Aquatimer generation in the early 2010s, consolidating the collection around a distinctive internal/external bezel system that allows safe, glove-friendly rotation without exposing the bezel to accidental knocks. The IW376803 variant, produced from 2014 onward, brought chronograph capability into this architecture, appealing to collectors who value both diving credentials and stopwatch utility. The Aquatimer line itself traces its roots to IWC's earliest water-resistant sport watches, giving the reference a lineage that resonates with tool-watch enthusiasts.
