IWC Aquatimer Chronograph IW379503 Charles Darwin
The IWC Aquatimer Chronograph IW379503 is a distinctive professional dive watch created as part of IWC’s Charles Darwin Foundation collaboration. Combining a substantial bronze case with a black dial, black rubber strap, and automatic chronograph movement, this Aquatimer delivers a rugged design with strong collector appeal.
The IWC Aquatimer Chronograph IW379503 features a 44mm bronze case with a matching bronze bezel. Bronze gives the watch a distinctive character that develops a natural patina over time, making individual examples increasingly unique through use.
Its black dial creates a strong contrast against the warm bronze case, while the sapphire crystal provides protection against scratches. The watch is rated to 30 ATM water resistance, reinforcing its purpose as a serious diving-oriented timepiece.
Powering the watch is the IWC Calibre 89365, an automatic mechanical movement with a 68-hour power reserve and 35 jewels. The movement provides both timekeeping and chronograph functionality, making the watch suitable for collectors who appreciate the combination of mechanical sophistication and practical timing functions.
The Aquatimer’s diving character is further emphasized by its rotating bezel and robust construction. The black rubber strap complements the bronze case while providing a practical material for a water-oriented watch. A bronze buckle completes the configuration.
The Charles Darwin designation connects this model to IWC’s conservation-focused Aquatimer editions associated with the Charles Darwin Foundation and the Galápagos Islands. This gives the reference additional significance beyond its technical specifications and makes it particularly interesting for collectors of limited or special-edition IWC sports watches.
This particular example is listed in used (very good) condition and shows only minor, intangible signs of wear. It is offered as a complete set with the original IWC box and original papers, adding value for collectors who prioritize original accessories and documentation.
The production year is unknown, so no specific production year is assigned to this individual example.

With its 44mm bronze case, black dial, automatic Calibre 89365, chronograph function, 30 ATM water resistance, and complete box-and-papers set, the IWC Aquatimer Chronograph IW379503 Charles Darwin is a compelling choice for collectors seeking a distinctive IWC diving chronograph with strong historical and environmental associations.
