Official description

Following the launch of the Montblanc Iced Sea Collection in 2022 with its frozen dials, Montblanc pushes the boundary even further in 2024 with the Montblanc Iced Sea 0 Oxygen Deep 4810. In the spirit of overcoming limits, Montblanc explores new territories at minus 4810 meters – inverting the 4810 meter height of the Mont Blanc Mountain to connect the world of the ocean to the mountain, which has always formed part of the Maison’s DNA.

Beyond its eye-catching aesthetics, this timepiece has been created to perform in extreme conditions. Engineered to withstand depths that only few watchmakers have dared to explore, its performance makes it a reliable companion in harsh underwater environments.

Housed in a 43mm titanium case with a shield protecting the screw-down crown, this new diving watch comes with a caseback adorned with a 3D engraving of the view divers see when diving underneath the ice. This mesmerizing effect is created in a three-dimensional colored relief that is achieved by a process of laser-generated oxidization that structures the metal with both matte and shiny finishes to create contrasts of color and texture.
