Montblanc Zero Oxygen Men's Limited Edition Leather Watch

This “Zero Oxygen” timepiece, limited to 290 pieces, has several benefits for explorers who need their equipment to work in some of the harshest environments. Zero oxygen inside the movement not only eliminates fogging, which can occur with drastic temperature changes at altitude, but also prevents oxidization. Without oxygen, all the components last far longer and will provide greater precision over time. Each timepiece comes with a zero oxygen certificate that attests to the fact that the watch has been successfully encased without oxygen. In addition to the certificate, each timepiece undergoes the Maison’s unforgiving 500-hour test.
