Where it all began.
The Decompression 01 marked the first mechanical translation of Bühlmann decompression theory into a wristwatch.

It was not designed to follow the codes of traditional dive watches, but to serve a specific purpose: making decompression logic mechanical and independent.

Developed in colllaboration with the scientific partners of Dr. A. Bühlmann, it established the foundation for everything that followed.

Produced in a limited production run, it quickly found its place among divers, professionals, and collectors who understood its purpose.

Today, it is no longer available.
The Watch
Decompression 01 represents the first mechanical implementation of Bühlmann decompression principles in a wrist-worn format.

Its architecture was defined by usability and clarity under real conditions, prioritising decompression readability over traditional dive watch conventions.

By translating a scientific model into a purely mechanical interface, it established the foundation for a new class of horological instruments.

This foundation is carried forward in the Decompression 02.
