A Bühlmann Watches & DAN Europe
PRODUCTION
The Story of Albert A. Bühlmann
Through rare archival footage and interviews with his son Thomas Bühlmann, former collaborators, and leading experts from DAN Europe, the documentary retraces the scientific quest that sought to answer one of diving’s greatest challenges: how to return safely from the depths.
More than a story about diving, this 36min Docufilm is a story of curiosity, perseverance, and a father and son connected by a scientific legacy whose impact continues to protect millions of divers around the world.
That makes this project more than a commemorative object. It is a chance to pause and look again at the history behind the tools we often take for granted and how they are shaping the future.
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.
InDEPTH is a free , independent online publication focused on the core pillars of modern advanced diving: exploration, training, science, conservation, human factors, and advanced diving equipment. It brings together long-form articles, expert voices, interviews, field reports, and thoughtful analysis for the technical diving community. With a clear focus on knowledge, safety, and responsible exploration, InDEPTH serves as an accessible reference and community platform for divers who want to better understand the underwater world and the decisions behind safe diving. www.indepthmag.com

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.
