MONTBLANC – 1858 Chronograph ORIGINS Bronze 46 Special Limited Edition - 2021
Click, to see the large size. ▶ BIG FOTOThe Montblanc 1858 Monopusher Chronograph Origins case has been made in a special alloy of bronze that will obtain an attractive patina over time and is reminiscent of exploration tools from the past. An “officer” case back has been added, just like in traditional pocket watches, protecting the movement, which is adorned with distinctive engravings on both sides. The outside of the “officer” case back features the head of the Minerva Goddess. The inside of the cover bears the inscription “Réédition du chronographe militaire Minerva des années 1930 doté d’un calibre fait main dans la pure tradition horlogère suisse” (Re-edition of a Minerva military chronograph from the 1930s equipped with a hand-made calibre following the Swiss watchmaking tradition).

Made of titanium, the metal must first be structured, which means that the decoration will be engraved by laser, taking into consideration the relief of the drawing.

For this limited edition, the execution of the movement is of particular note as the main plate and bridges have been left in raw Maillechort (also called “German-silver”), a high-end traditional material used in Minerva movements in former times.
