Editor's Notes

Montblanc's '1858 Geosphere' watch is made in homage to the world's Seven Summit challenge, the holy grail for mountaineering explorers. Limited to only 290 models, it's crafted from robust stainless steel and takes its shape from the legendary 'Minerva' watches of the 1920s and 30s, specially designed for explorers. It's MB 29.25 automatic movement powers the glacier-patterned dial which features two 24-hour Northern and Southern hemisphere sub-dials with luminescent continents and the seven summits marked with small red dots. It's finished with a leather-trimmed canvas strap that's both hard-wearing and comfortable.
