1858 - GEOSPHERE 0 OXYGEN LIMITED EDITION | 129415

The 1858 Geosphere 0 Oxygen Limited Edition is totally devoid of oxygen to improve the watch's performance and precision over time, even in some of the harshest mountain environments. Zero oxygen inside the movement not only eliminates fogging, which can occur with drastic temperature changes in 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 42mm bronze case with a bi-directional knurled ceramic bezel with luminescent cardinal points and the Maison's glacier pattern dial. The watch is powered by the MB 29.25 automatic movement with manufacture complication. Like with all 1858 Geosphere models, both the Northern and Southern hemispheres are represented with two three-dimensional globes and include a day & night indication so that the wearer can see what time it is across the Earth with a simple glance.
