In May 2022, he will undertake an expedition to the summit of Mount Everest, without supplemental oxygen, while wearing the Zero Oxygen watch. Such is the commitment of the watchmakers to give explorers only their best through research, superior mechanics, and a resounding testament. The watch employs specific oils for the movement, which perform effectively a...
