Our factory direct promise
The Bühlmann design DNA is found in its oversized minutes hand which has the purpose of reading the dial and bezel diving data. This oversized hand allows the diver to focus on the diving information, in particular the actual dive time (ADT) and the decompression security stops time and depth, instead of on time.
Additionally, the case is inclined by 5 degrees to facilitate the data readability even more. To place the focus on the minutes hand, the hour hand is replaced by a hours digits disc.
We designed it like Albert Bühlmann would have done
Superluminova® pigments are Swiss made and offer the strongest possible afterglow performance. The pigments are non-radioactive, REACH compatible, highly temperature resistant and resistant to environmental influences.
Grade X1 used on the Decompression 01 shows a performance increase of up to 60% after two hours compared to standard grades. Long term legibility according to the ISO 3157 standard is extended by at least a factor of 1.6.
We designed the Bühlmann Decompression 01 like A. Bühlmann would have done. We have integrated 35 years of breathing science, empirical tests and depth records by functionally featuring his algorithm on the uni-directional turning bezel of the watch. This required a special re-design of the circular calculator itself, as well as a new dial and time reading configuration to make the scale usable on a timepiece and safe for diving. Together with Thomas Bühlman, the son of Alfred Bühlmann, and his team we have adopted new solutions for a diving watch to make it special, unique and professional.
The legacy of Prof. Bühlmann lives on in the Decompression 01.
