Montblanc 1858 Geosphere Automatic - 125872

Pre-owned 2026

The Montblanc 1858 Geosphere draws its lineage from the legendary Minerva military watches of the 1920s and points it directly at mountaineering, dedicated to the Seven Summit challenge. The 42mm steel case carries a bi-directional rotating titanium bezel with black ceramic compass markings, and two domed globes, northern and southern hemispheres, rotate in opposite directions completing a full turn every 24 hours, the red dots across their surfaces marking the world's great peaks. It is a manufacture worldtime complication built by Montblanc's watchmakers in Villeret, functional rather than decorative. Calibre MB 29.25 powers it automatically with 42 hours of power reserve at 28,800 vph. 2026 production, impeccable condition, box and papers included, bracelet fitted for a 7.5 inch wrist and beyond. The Geosphere is world time built for someone who actually crosses time zones rather than someone who simply wants to look like they do.

“Watch was rated as "very good" by authentication center, but after examining it under a 10x loupe, I can't understand how it wasn't rated as "like new." Not a single sign of wear that I could see. Very pleased with my seller; we had a pleasant and reasonable negotiation after my high bid was below his reserve, and reached a price we were both comfortable with. The watch is exactly as he described. A++++ seller.”
