Decompression 02 is a dive watch by Bühlmann Dive Watches and is produced and promoted by Watch Angels.

The Decompression 02 is the functional and usability evolution of the Bühlmann Decompression 01, first introduced in 2021. It is the first mechanical dive watch to feature a Twin Safety Diving Bezel and a Twin Decompression Stops Dial to safely manage decompression stops for dives in the “Golden Zone”.

The foundations of modern dive safety were laid by Prof. Albert A. Bühlmann, whose pioneering research from the late 1950s to the 1980s resulted in the ZH-L16 decompression algorithm, a model still employed by most dive computers and tables today. Bühlmann's work was revolutionary for its completeness, as it addressed decompression at sea level and at altitude, thereby creating a model applicable to the full range of diving environments.

The Decompression 02 incorporates the ZH-L16 decompression algorithm and has been conceived in collaboration with professional divers. Furthermore, it has been functionally validated by decompression science specialists, including former members of the Bühlmann research team, the Divers Alert Network (DAN) Europe and the World Underwater Federation Switzerland (CMAS Switzerland).
