Aquatimer Automatic 2000

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.

What it is

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.

Buying notes

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.

Market read

Pre-owned IW358002 examples currently trade in the $4,500 to $6,500 range depending on service history, box-and-papers completeness, and case condition. The titanium bracelet version commands a modest premium over the rubber strap configuration because the metal bracelet is no longer available new. Lightly worn examples with original bracelet and recent service sit toward the top of that band.

The watch is not chased by speculators, which means pricing is rational and negotiable, particularly on examples with heavy case wear that suit a buyer who actually plans to use it.

Service expectations

The caliber 80110 carries an IWC-recommended service interval of approximately five years, with factory service running $600 to $900 depending on parts and the service center's region. Independent watchmakers familiar with ETA-derived movements can service it for considerably less, typically $250 to $450, though IWC will not re-certify water resistance unless the work is done in-house or by an authorized center. For a watch rated to 2000 meters, pressure testing after any service is not optional.
