After striving for great heights, Montblanc plunges into uncharted depths at 4810 meters below sea level
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.
More than a Dial
Like with all the Iced Sea timepieces, the Montblanc Iced Sea 0 Oxygen Deep 4810 dial was inspired by the ice of one of the Mont Blanc mountain’s largest glaciers – the Mer de Glace – with its interlocking network of crystals that have been frozen in time for millennia, giving each dial the impression of genuine depth and luminosity. This creative technique is called gratté-boisé and is not only special in watchmaking, but takes four times longer to make than a standard dial. The blue color is accentuated with a sfumato effect and depicts the tone of ice found deep under the sea, which is especially fitting for a watch that can descend to 4810 meters beneath the water.
As the timepiece needs to be visible in all conditions, Montblanc has incorporated white Super-LumiNova® into the hands, indexes and a dot at 12 o’clock which all glow in a luminescent shade of blue in low light, in keeping with the glacial theme.
Zero Oxygen
The Montblanc Iced Sea 0 Oxygen Deep 4810 joins the Maison’s series of “Zero Oxygen” timepieces that feature several benefits for explorers who need their equipment to work in harsh environments. Zero oxygen inside the case not only eliminates fogging, which can occur with drastic temperature changes, but also prevents oxidization. Without oxygen, all the components last longer and will provide continued precision over time. Each timepiece comes with a certificate as proof of this special, yet invisible, technology and guarantees that it has been successfully encased without oxygen.
All the Details
Powered by Montblanc’s manufacture, COSC-certified, automatic MB 29.29 movement, with approx. five days of power reserve, this deep diving timepiece indicates the hours, minutes, seconds, and a date at 3 o’clock. It is also completed with an interchangeable black rubber strap which is tapered in a V-shape and can be easily adjusted directly on the wrist, even when wearing a wetsuit, so all owners can find their suitable fit.
In addition to being a veritable diving instrument conforming to the ISO 6425 standard and the Montblanc Laboratory’s battery of tests, the Montblanc Iced Sea 0 Oxygen Deep 4810 is also an highly wearable sports watch that can be worn for various activities – whether you are plunging into the depths of the ocean or ascending mountain summits.
