Dedicated to the world’s Seven Summit mountaineering challenge, which is known as the holy grail of mountaineering adventures, the Montblanc 1858 Geosphere UltraBlack comes in a 42mm distressed stainless steel case combined with black and contrasting white design details.

Function-wise, the timepiece features a manufacture world-time complication developed by the Montblanc watchmakers in Villeret: two domed globes, turning in opposite directions that complete a full rotation in 24 hours. Surrounded by a scale with the 24 time zones, along with a day and night indication in contrasting colours, the watch expresses the spirit of mountain exploration, while embodying the modern trend of returning to nature.
