The Montblanc 1858 Date 0 Oxygen captures the essence of mountain exploration with its sfumato green glacier-pattern dial inspired by emerald “jade bergs.” The 41mm stainless steel case is entirely oxygen-free and accented by a black ceramic bezel with luminescent cardinal points. Powered by an automatic movement, it offers hours, minutes, seconds, and a date display. The watch is completed with an interchangeable stainless steel bracelet featuring a fine adjustment system and an engraved “Spirit of Exploration” case back.
