Inspired by 'Minerva' styles from the '20s and '30s, Montblanc's '1858 Geosphere' reference celebrates the spirit of mountain exploration. Dedicated to the Seven Summit mountaineering challenge, it's designed with a robust stainless steel 42mm case and matching bracelet strap. Inside, a MB 29.25 automatic movement powers the black dial featuring hour and minute hands as well as a second time-zone sub-dial and two 24-hour Northern and Southern hemisphere sub-dials with day and night indicators, where the seven summits are pinpointed with red dots.
