Editor's Notes

Embodying the spirit of mountain exploration, the Montblanc '1858 Geosphere 0 Oxygen' features a sfumato green glacier-patterned dial inspired by emerald icebergs. It's housed in an oxygen-free stainless steel case with a bi-directional green anodised aluminium bezel and luminescent cardinal points. The MB 29.25 calibre automatic movement powers a date function, worldtime complications, rotating hemispheres, a 24-hour scale, Day & Night indicators and dual-time display. Turn it over to appreciate the 3D laser engraving of Mont Blanc.
