Editorial
The Aquatimer 2000 is the dive watch IWC actually meant for the water. Rated to 2000 meters, built in titanium, and sized at 46mm, it targets saturation divers and serious underwater professionals rather than the lifestyle market. Discontinued in 2020 after a six-year run, it is now the most capable dive reference IWC has ever produced.
IWC introduced the IW358002 in 2014 as part of a full Aquatimer family refresh that also included 300m and 500m variants. The movement is the caliber 80110, a self-winding ebauche based on the ETA 2892 architecture, running at 28,800 vph with roughly 42 hours of power reserve. The defining mechanical feature is IWC's twin-bezel system: a rubber-armored outer bezel actuates an inner bezel through a push-through mechanism, keeping the timing ring inside the crystal and protecting it from accidental adjustment.
The titanium case kept weight manageable for a 46mm tool watch. IWC retired the line in 2020 without a direct replacement at the 2000m depth rating, leaving this generation as the only one to carry that specification.
The inner bezel coupling mechanism is specific to IWC and requires factory service if the clutch wears or slips. Check that the inner bezel clicks positively and does not drift when the outer ring is rotated, since a worn clutch is a service bill the seller rarely flags. The titanium case scratches readily and deep gouges from actual dive use are common; inspect under good light and decide whether a refinished case or honest wear marks matter to your collection.
Crown and case-back gaskets should be verified as recently serviced before any water use regardless of what the seller says, since gaskets age on the shelf as well as in service. The 80110 caliber is serviceable by any competent independent watchmaker, but IWC will ask for complete disassembly plus pressure testing, so budget accordingly.
