The Montblanc 1858 Geosphere 0 Oxygen limited edition is totally oxygen -free to improve the performance and precision of the clock over time, even in the most difficult mountain environments. The total absence of oxygen within the movement not only avoids the fogging, which can occur in the case of sudden changes in temperature at altitude, but also prevents oxidation. Thanks to the absence of oxygen, all components last much longer, ensuring even more accurate precision over time. The timepiece is equipped with a bronze case of 42 mm with a bidirectional zigrinated ceramic bezel with luminescent cardinal points and dial with the "glacier" motif of the maison. The clock is powered by the MB 29.25 automatic movement with a manufacturing complication. Like all 1858 Geosphere models, both the northern hemisphere and the southern one are represented with two three -dimensional globes and include a day/night indication so that the wearer can know that now it is now in every part of the world, with a simple one gaze.
