Pre-owned IWC Aquatimer Chronograph ref IW376804 (2014). The Aquatimer has been an important part of the brand’s catalog since the late 1960s, with a purpose-built watch designed for underwater exploration. This example features a robust 44mm stainless steel case and a legible black dial. The chronograph layout is arranged in a classic tri-compax configuration, while twin windows at 3 o’clock display both the day of the week and the date. Large hands, bold hour markers, and generous luminous material ensure excellent visibility in low-light conditions, whether you’re underwater or simply checking the time after dark. One of this Aquatimer’s defining features is its inner rotating dive bezel. Rather than placing the timing scale on the outside of the watch, IWC integrated a 60-minute rotating bezel beneath the crystal. This system helps protect the scale from accidental impacts while giving the watch a distinctive appearance compared to traditional dive watches. Shop IWC Aquatimer Collection
