Bühlmann Decompression 02

The evolution of the mother of all dive watches. By integrating the Bühlmann decompression calculator and by featuring and entirely new usability for divers, the Bühlmann Decompression 02 is one of the most ingenious and impressive mechanical dive machines ever made. From the Swiss pioneer of depth and dive security. Angel round October 2025.

ZH-L 16B

The patented dial design features the ZH-L 16B Bühlmann decompression stops calculator.

575m

The Decompression 02 is water-resistant up to 575m - 1668ft.

5° Inclination

A case inclination of 5 degrees ensures optimal information legibility.

Double bezel

The only dive watch featuring two counter-rotating diving bezels for decompression stops and TDT.

Fly-no Fly

The BD02 features an ingenious fly-no fly indicator which you can set after every dive.

XXL Minute hand

The BD02 features the signature Bühlmann XXL dive minute hand to measure decompression stops.

The mother of all dive watches

Safe diving started with decompression science. By allowing the calculation of the decompression stops using the Bühlmann ZH-L 16B calculator, the Decompression 02 deserves the defintion of "mother of all diving watches".

1000 overpressure tests

Dr. Albert Bühlmann incorporated the empirical results obtained in over 1.000 overpressure tests in the sea and in the Druckkammer into a computer model to enable the dive calculations across different variables like: dive height (ABSL), dive length, dive depth, dive profile, breathing gas used and type of dive (single or repetitive).

Decompression stops dial

The Bühlmann Decompression 02 features an entirely new usability. In this second model of the Bühlmann saga, the decompression stops data has been moved to the dial. This patented design allows an easy calculation of the decompression stops in combination with the decompression stops time bezel.
