Introducing Bühlmann Decompression 02: Where Swiss Watchmaking and Dive Science Form an Unparalleled Alliance

Published: 19 Dec 2025
The Bühlmann Decompression 02 watch reshapes the landscape of mechanical dive watches by fusing timeless Swiss horology with groundbreaking diving science.

Exceptional innovation is an elusive trait within the realm of mechanical watchmaking, and within the diving watch category, it’s more of an exception than a norm. Shattering this narrative, the Bühlmann Decompression 02 forges an unexplored path. It goes beyond merely borrowing visual cues from the world of diving, instead injecting key elements of diving science into its very fabric to enhance safety, functionality, and design.

At the heart of Decompression 02’s revolutionary design lies the genius of Dr. Albert A. Bühlmann, the Swiss physician and researcher who raised the bar for diving safety with his groundbreaking ZH-L16 decompression algorithm. Today, Bühlmann’s algorithm serves as the backbone for the majority of modern dive computers and continues to set global standards for dive tables. Bühlmann Dive Watches, helmed by Dr. Bühlmann’s son, Thomas Bühlmann, was born with the mission to carry forward his father’s vision and innovative approach.

This revolutionary dive watch stands out for its patented Bühlmann Twin Safety Bezel®, an unprecedented feature in a mechanical dive watch that allows divers to safely monitor both the total dive time and the decompression stop times. Additional standout characteristics comprise the Twin Decompression Dial®, reflecting decompression stop data, and a fly-no-fly indicator. All elements incorporated into this archetypal timepiece are engineered to perfectly align with the lifestyle and safety needs of recreational divers and technical divers alike. The Bühlmann Decompression 02 is more than a watch - it’s a testament to science, safety, and the spirit of exploration.
