1858 Geosphere Chronograph 0 Oxygen Limited Edition

The Montblanc 1858 Geosphere Chronograph 0 Oxygen Limited Edition of 290 pieces is totally devoid of oxygen to guarantee the watch's performance and precision over time, even in some of the harshest mountain environment. 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. The timepiece comes in a lightweight 44mm polished titanium case. It is powered by Montblanc's MB 29.27 Manufacture automatic chronograph movement with worldtime complication.
