Pre-Owned IWC Aquatimer Chrono ref IW371933 (2007). This generation of the Aquatimer was produced from 2004 to 2009 and takes a different approach to the dive watch formula, with a more technical, purpose-built design set than IWC’s pilot lineup. Most notably, the internal rotating bezel, adjusted via the lower crown, protects the timing scale while giving the case a distinctive dual-crown look. The black dial is clean but functional, with a chronograph layout and a day-date display at 3 o’clock. The 42mm stainless steel case wears solid on the wrist, paired with an integrated rubber strap that’s sporty and durable. It’s a slightly under-the-radar IWC, but one that has a lot of utility and a design you don’t see nearly as often. Shop IWC Aquatimer Collection
