Notes

The Montblanc 1858 Geosphere honors the legendary Seven Summits mountaineering challenge through its sophisticated world-time complication. Housed in a 42mm titanium case adorned with glacier-inspired blue and icy white details, this timepiece features two luminescent hemisphere globes that rotate in opposite directions, completing full rotations every 24 hours. Surrounded by 24 time zone indicators with day/night visualization, the watch seamlessly blends the heritage of 1920s-30s military-grade Minerva timepieces with modern exploration aesthetics, embodying both horological excellence and the spirit of mountain adventure.
