Technical Brilliance

The IWC Aquatimer series exemplifies a seamless blend of functionality and high-tech engineering, setting a benchmark in the domain of dive watches. 

Each timepiece in this collection has been developed with an emphasis on robust construction and high-pressure resistance, ensuring that it remains impenetrable even at depths where pressure is exceedingly high.

Here’s a look at its watches’ technical features:


  • Depth Tolerance: Water-resistant to 30 bar

Rotating Bezels:

  • Purpose: For tracking dive time
  • Operation: Externally or internally mounted, with IWC’s SafeDive system


In luminescent detailing, IWC leverages Super-LumiNova® to ensure that Aquatimer watches maintain their legibility under the murky realms of the ocean. This glow-in-the-dark coating on the hands and markers becomes a pivotal feature for divers who rely on absolute clarity to monitor time during underwater expeditions.

The movements powering IWC’s Aquatimer watches are equally impressive. Their recent shifts to in-house movements underscore a commitment to precision and durability. 

Notably, a transition from the conventional ETA 2892-A2-based 30120 movement to their automatic manufacture movement is marked by substantially increased power reserves.

Power Reserve:

  • Before: 42 hours
  • After: A generous 120 hours (approximately)

The in-house movements are not just about longevity; they also signify IWC’s dedication to craftsmanship and innovation. These mechanical hearts beating inside the Aquatimer models are a testament to the brand’s prowess in combining traditional watchmaking techniques with state-of-the-art technology.

The Aquatimer Automatic stands as an epitome of technical brilliance, offering divers a dependable and technically sound companion for their oceanic adventures.
