present the online première of the Docufilm:
the Swiss Pioneer of Dive Safety.
25th of June 2026 at 4pm CEST
For recreational and technical divers, it is a return to first principles—and a reminder that every dive profile rests on decades of disciplined inquiry.
Dr. Albert A. Bühlmann (1923–1994) was a Swiss physician and pioneering researcher in decompression science at the University Hospital of Zurich. His work on inert gas kinetics and tissue compartment modeling led to the development of the Bühlmann decompression algorithms, which remain the foundation of modern dive planning and are widely implemented in dive computers today. Through decades of rigorous experimentation in hyperbaric chambers and real-world conditions, he transformed decompression from empirical practice into a structured scientific discipline.
Prof. Alessandro Marroni is a physician, researcher, and founder of DAN Europe, one of the world’s leading organizations dedicated to diving safety and medical research. A key figure in the advancement of diving medicine, he has led extensive studies on diver physiology, risk prevention, and decompression practices. In recent years, his work has focused on developing the ideal decompression algorithm—building on and extending the legacy of Dr. Albert A. Bühlmann to further refine personalized and data-driven approaches to diving safety.
In Depth Magazine is an independent publication dedicated to advanced and technical diving, exploring the science, technology, and human factors behind underwater exploration. Known for its rigorous editorial approach and contributions from leading experts in the field, it provides in-depth analysis on decompression theory, equipment, and diving practices. The magazine serves as a reference platform for divers seeking a deeper understanding of the principles that underpin safe and informed diving.

Better, bolder and safer, it is conceived as an effective analog mechanical back-up instrument inspired by the science of safe diving.
The twin turning dial features the 0-700m ASL Bühlmann circular decompression table, operated in connection with the Twin Safety Bezel to measure decompression stops and total dive time.
Powered by the sophisticated and reliable Swiss made SW300 automatic movement and produced in a limited edition of 575 pieces, the Decompression 02 is not merely a professional dive watch - it is a tribute to the scientific foundations of modern diving.
