This Montblanc 1858 Geosphere limited edition to 1990 pieces has taken its inspiration from the South Pole explorations on the Antarctic continent. The watch is powered by Montblanc’s automatic movement with Manufacture Worldtime complication – the Caliber MB 29.25 – that indicates the time around the world thought distinctive luminescent turning globes; it also indicates day & night displays, a dual time, and a date. Housed in an ultralight 42mm titanium case completely devoid of oxygen, this new technical innovation has several advantages for explorers by eliminating fogging and preventing oxidization, thus allowing the movement to last far longer with greater precision. The timepiece is fitted with an iced blue sfumato glacier pattern dial and matching colored bi-directional anodized aluminum bezel and is available with an interchangeable tapered bracelet with a fine adjustment system and a gray textile strap with a rope pattern. On the case back, is a 3D laser engraving of a frozen landscape with the Aurora Australis.
