Editor's Notes

Crafted in a limited run of just 1858, Montblanc's 'Géosphère' watch is ideal for avid travellers and frequent fliers. Engraved on the back with 'Spirit of Mountain Exploration' lettering, the bronze case houses a precise MB 29.25 automatic movement and army-green dial with day and night displays, each dedicated to the northern and southern hemispheres. Super-LumiNova®-coated red gold hands, numerals and indices, and the domed anti-reflective sapphire glass crystal all ensure clear legibility of two time zones simultaneously, while the NATO strap offers superb durability.
