Capturing the spirit of mountain exploration, the sfumato green glacier pattern dial of this Montblanc 1858 Automatic Date 0 Oxygen is inspired by the deep green colour of the emerald icebergs or “jade bergs”. The timepiece is housed in a 41 mm stainless steel case totally devoid of oxygen with a fixed black ceramic bezel with luminescent cardinal points. It is fitted with an interchangeable stainless steel bracelet with taper and fine adjustment system and an engraved case back featuring the “Spirit of Exploration” special engraving.
