Description
The Montblanc 1858 Geosphere was introduced in 2018. It features a stainless steel case of 42mm, which is fitted with a rotating bezel in ceramic and a closed & engraved back. It is motivated by the self-winding caliber MB 29.25, which features rotating globes at 12:00 and 6:00, a second time zone at 9:00, and a date window at 3:00.
Reference 117838 is fitted with a brown 'sfumato' aged calf leather Bund strap with beige stitching coming from the Montblanc Pelletteria in Florence. Reference 119286 is identical but fitted with a more conventional cognac-coloured aged calfskin strap with beige stitching. Reference 117837 is fitted with a black NATO strap.
Movement
Caliber MB 29.25 is based on the Sellita SW300, fitted with an in-house module that features a worldtime complication with two turning domed hemisphere globes, which make a full rotation in 24 hours. The northern hemisphere at 12 o'clock turns anticlockwise, while the southern hemisphere turns clockwise. They are both surrounded by a scale with the 24 time zones, along with a day/night indication in contrasting colors.
