Editor's Notes

"Built for those who travel the world in their perpetual quest for exploration", Montblanc's '1858 Geosphere' watch is a limited-edition release to celebrate the 160th anniversary of the Minerva manufacture in Villeret, Switzerland. Dedicated to mountaineers and the Seven Summits Challenge, it features Northern and Southern hemisphere globes at 12 and 6 o'clock, respectively, with each peak pinpointed in red, and is engraved with the ranges on the back. The hardy bronze case is set with a bidirectional ceramic bezel and it's affixed to a brown burnished-leather strap so it looks and feels like a vintage timepiece.
