Montblanc · Family: 1858
The Montblanc 1858 Automatic Date 0 Oxygen MB133269 is a 41mm steel exploration watch with a "0 Oxygen" case (an air-free inner atmosphere designed to prevent crystal fogging), a green "glacier" pattern dial, and a black ceramic bezel. It runs an in-house automatic caliber with 38 hours of power reserve. Cazador has no verified price observations yet (n=0). This marks Montblanc's first entry into Cazador's catalog. Its standout detail: Montblanc's "0 Oxygen" technology fills the case interior with an inert gas instead of air, to eliminate crystal fogging under extreme conditions.

Montblanc entered high-end mechanical watchmaking in 2007 by acquiring Minerva, a movement manufacture founded in 1858 in Villeret, in the Swiss Jura, historically celebrated for its chronograph calibers from the 1920s and 1930s. In 2018, coinciding with Minerva's 160th anniversary, Montblanc launched the 1858 collection — taking its name from that manufacture's founding year — as its line of exploration watches inspired by Minerva's 1930s pilot and mountain watches.
Within that collection, the "0 Oxygen" series introduces an unusual technical solution: instead of filling the case with standard air during assembly, Montblanc fills it with an inert gas, removing oxygen from the interior. The goal is to prevent crystal fogging from condensation during sharp temperature swings, a common issue for exploration and mountain watches exposed to extreme thermal shifts.
Reference MB133269 pairs that architecture with a green "sfumato glacier" pattern dial, inspired by the color of ancient glacial ice, and a fixed black ceramic bezel with luminescent cardinal points instead of the graduated rotating bezel typical of a dive watch, reinforcing its focus on mountain and exploration use rather than diving.
This is Montblanc's first reference in Cazador's catalog, extending the project's coverage beyond traditional Swiss manufactures to a German house whose watch division is built on acquired technical heritage — that of Minerva.

Montblanc acquired Minerva, a movement manufacture founded in 1858 in Villeret, in 2007. The 1858 collection takes its name from Minerva's founding year and draws on its historical pilot and mountain watches.
Sources consulted are inconsistent, citing between 21 and 25 jewels for this caliber; Cazador does not publish that figure until it can be confirmed directly with Montblanc.
No. Its black ceramic bezel is fixed, with luminescent cardinal points, geared toward mountain and exploration use rather than diving.
