Montblanc's 1858 Collection timepieces have been designed as tool watches for mountain exploration, taking inspiration from the legendary Minerva pocket watches and chronographs from the 1920’s and 1930’s originally conceived for military use thanks to their precision and robustness. With its latest 1858 Geosphere timepiece showcasing a design as strong as the innovation within, Montblanc pushes the concept of oxygen – the central element in any intrepid ascent – even further than before.

A Middle Case Material Containing CO2

Montblanc’s new watch case material is created using a pioneering process that captures CO2 from biogas production and mineral waste produced by recycling factories, thanks to a process of calcium dissolution and carbonation.

The obtained powder containing CO2 – CACO3 – is then combined with ultra-light and resistant carbon fibre. Together, they create an innovative composite material, the CARBO2, which is shaped into a watch middle case.

In addition to the technological aspect of the case, the resulting CARBO2 material has a graphic aesthetic, with its dark shades depending on the particular mix of carbon fibre and CACO3, lending itself well to the Montblanc 1858 Geosphere 0 Oxygen. Like the fearless alpinists and adventurers who dedicate their lives to exploring the planet’s mountainous wilderness, this material is also opening up new paths of exploration.

Reinforcing the theme of adventure, the 43.5mm titanium and CARBO2 case comes with an engraved luminous blue outline of the Mont Blanc Mountain on the side that only the timepiece’s wearer can see. The older glaciers are, the less oxygen they contain and the denser they become, resulting in a deeper blue color that has been depicted on the case band – shining white by day and luminous blue by night.

To achieve such a result, Super-LumiNova® and a layer of protective varnish are applied by hand with particular care. An image of the Mont Blanc mountain also adorns the titanium caseback, created using Montblanc’s 3D laser technique that depicts the color, depth and realism of this natural wonder.

Zero Oxygen

This Montblanc 1858 Geosphere 0 Oxygen CARBO2 limited edition 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 at altitude, but also prevents oxidization. Without oxygen, all the components last longer and will provide continued precision over time. Each zero oxygen timepiece comes with a certificate as proof of this special, yet invisible, technology and guarantees that it has been successfully encased without oxygen.

The timepiece is powered by the MB 29.25 automatic movement with Montblanc’s Manufacture worldtime complication, which includes turning Northern and Southern Hemisphere globes with blue Greenwich meridian lines and 14 dots for each of the 8000m peaks. It also displays a Day & Night indication, a 24-hour scale, dual time display, and a date.

  Click, to see the large size. ▶ BIG FOTO   

The timepiece comes with a bi-directional titanium ceramic fluted bezel with blue luminescent cardinal points and a blue gasket under the sapphire crystal. It is fitted with a black sfumato glacier pattern dial that captures the texture of glacial ice with its interlocking network of crystals that have been frozen in time for millennia. Crafted using a special technique called gratté-boisé, this dial process takes four times longer than standard techniques.

To pay homage to its namesake mountain on the caseback, Montblanc uses a special technique to create an authentic 3D rendering that provides depth and realism. 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 original drawing. Next, the desired finish (matte and shiny) is similarly achieved by laser. In the final phase, colors are created with laser-generated oxidation, with the level of oxidation determining the final result.

Completing the timepiece is a black interchangeable rubber strap featuring a taper and a fine adjustment system, with the pattern reminiscent of the textiles used by mountaineers.

MONTBLANC – 1858 Geosphere 0 Oxygen CARBO2 Only Watch 2023

 

MONTBLANC – 1858 GÉOSPHÈRE 0 Oxygen CARBO2 Only Watch Unique Piece 2023

To see Montblanc’s Only Watch 2023 timepiece, you will not only have to bid on it, you will also need to use an ice pick to get to it.

Click, to see the large size. ▶ BIG FOTO

This is the fourth time Montblanc has participated in Only Watch and this time around, the Maison is offering so much more than a unique timepiece. The Montblanc Only Watch 2023 timepiece is a one-of-a-kind 1858 Geosphere 0 Oxygen that is introducing an entirely new middle case material that has captured CO2 inside. And if that isn’t ‘cool’ enough, the unique piece is encased in a block of ice (safe breakable glass) without oxygen inside, which means the watch’s future owner will need to smash it open with an ice pick to get to it, or leave it captured in time – it is entirely up to them!

A Case in New Material Creation

The new case material is created using a pioneering technological development that captures CO2 from biogas production and mineral wastes from recycling factories, thanks to a process of calcium dissolution and carbonation.

Reinforcing the world of adventure and exploration, the 43.5mm case comes with a luminous glacier blue outline of Mount Everest on the side that only the wearer can see. The older glaciers are, the less oxygen they contain and the denser they become, resulting in a deeper blue colour that has been depicted here on the case band, shining white by day and luminous blue by night. A beautiful picture of Mount Everest also adorns the titanium case back using Montblanc’s 3D laser technique that depicts the colour, depth and realism of this natural wonder.

Next to Mount Everest, the 13 other highest peaks of the World are mentioned and marked in colour in tribute to alpinists who dared to climb them.

Zero Oxygen

This Montblanc 1858 Geosphere 0 Oxygen Only Watch 2023 one-of-a-kind timepiece joins the Maison’s series of “Zero Oxygen” timepieces and will introduce a new collection based on this piece that will be revealed in April 2024. Like all of Montblanc’s 0 Oxygen pieces, this unique piece features 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 at altitude, but also prevents oxidization. Without oxygen, all the components last longer and will provide unfaltering precision over time. Each zero oxygen timepiece comes with a certificate as proof of this special, yet invisible, technology and guarantees that it has been successfully encased without oxygen.

The timepiece is powered by the MB 29.25 automatic movement with Montblanc’s Manufacture worldtime complication, which includes turning Northern and Southern Hemisphere globes, a 24-hour scale, Day & Night indications, dual time display, and a date. The timepiece comes with a fluted bi-directional black ceramic bezel with the compass cardinal points and “OW” for “Only Watch” depicting West. The timepiece is fitted with an electric blue glacier pattern dial and the worldtime meridians in a spectrum of colours, in keeping with Only Watch’s 2023 rainbow colour theme. Completing the look is a black interchangeable textile strap, which top material is made of 100% recycled PET.

From the Top of the Mountain

In addition to the timepiece, the lucky bidder will receive an ice pick from Montblanc’s Mark Maker, world record-breaking alpinist Nimsdai Purja, who is the fastest man to climb all 14 of the world’s highest peaks above 8000 metres, a record he broke in six months and six days. He also ascended Mount Everest without supplementary oxygen for a collaboration with Montblanc in 2022. 

For this unique piece, Nimsdai has donated his ice pick and written a note to the watch’s future owner about how he sees the world in 100 years. This hand-written note, along with the watch, has been encased in a zero-oxygen ice-like capsule. To access the watch, the future owner will need to take Nimsdai’s ice pick to break the case, or they can, of course, leave this difficult decision to the next generation if they so choose. What would you do?

About Only Watch

This year marks the 10th Only Watch charity auction, a biennial event that has raised over CHF/EUR 100 million to date. Only Watch was created in 2005 by Luc Pettavino – and under H.S.H. Prince Albert II of Monaco’s high patronage – to auction one-off timepieces to raise funds to support researchers around the world to accelerate their work to find a cure for Duchenne Muscular Dystrophy. Thanks to the mobilization of the watch industry, this initiative has become a highlight on the horological calendar for both brands and collectors. Montblanc is honoured to be part of this important journey and hopes that this year’s timepiece will bring as much enjoyment to its future owner as it did to the Montblanc team who worked on bringing it to life.

MONTBLANC – 1858 The Unveiled Secret Minerva Monopusher Chronograph Edition

 

MONTBLANC – 1858 The Unveiled Secret Minerva Monopusher Chronograph Limited Edition 2023

Click, to see the large size. ▶ BIG FOTO    

Leveraging the remarkable expertise in chronograph development of the 165 years old Manufacture Minerva, Montblanc has added a new face to its Montblanc Unveiled Secret Minerva Monopusher Chronograph, this time executed in distressed steel. 

Click, to see the large size. ▶ BIG FOTO   

This limited edition of 88 pieces launched at Watches and Wonders 2023 renders the model a more contemporary look and pushes the limits of aesthetic and technical excellence even further.

A Limited Edition Speciality With Incredible Details Inside Out

The latest execution of the Montblanc Unveiled Secret Minerva Monopusher Chronograph in distressed steel results from a unique treatment of the 43mm stainless steel case with a black coating. Manual washing and brushing of the material with quartzite serve each timepiece’s unique patina and appearance.

Click, to see the large size. ▶ BIG FOTO 

This new iteration launched at Watches and Wonders features a white gold fluted bezel which derives inspiration from Minerva’s first fluted bezel dating back to 1927, further enhancing the refinement of the timepiece. The watch is paired with a black nubuck alligator strap on which the triple-folding steel clasp also adorns a distressed look.

The watch case back is engraved with an image of the historic Minerva Manufacture.

The Monopusher Chronograph – A Remarkable Technical Feat

To highlight at the center stage of the timepiece, all the incredible hand-finished components of the historic manual-wound Minerva MB M16.29​ movement, the entire caliber was inverted. 

Click, to see the large size. ▶ BIG FOTO   

This first-of-its-kind feat for a Minerva movement in the history of the watch industry created unique challenges and a gear train of 21 additional components was added to the already existing 252 movement parts to enable the hands to turn in the right direction post caliber inversion.

Click, to see the large size. ▶ BIG FOTO  

The entirely hand-made movement is crafted by one watchmaker from start to finish. Displaying all the mechanical action on the dial side of the watch reveals the magic of the chronograph action, making it an object of desire for watch lovers who wish to admire the movement without altering their timepieces.

 Click, to see the large size. ▶ BIG FOTO     

And just for fun, the Maison has turned the last digit of the reference number upside down to represent this change, so MB M16.29 becomes MB M16.26.

Click, to see the large size. ▶ BIG FOTO

Turning a movement over sounds simple, but it is a technical feat as the direction of the hands also has to be reversed. The MB 16.29 calibre was one of the only movements in Montblanc’s stable of chronographs where this could be achieved and reversing the time required the addition of 21 components, making this more than an aesthetic feature, but a truly technical one too. 

Click, to see the large size. ▶ BIG FOTO      

And just for fun, the Maison has turned the last digit of the reference number upside down to represent this change, so MB 16.29 becomes MB 16.26👆.   

 

In 165 years of Minerva history, this has never been done before. It is surprising when you think of how many watch lovers remove their chronographs to admire the movement through the case back. Well, now they don’t have to!

An Interrupted View Of The Hand-Finished Movement, Better Than A Dial

Immediately perceived upon view through the sapphire crystal, the depth of the chronograph caliber layers, the detailed level of finishing on the sanded German silver movement, and the beauty of the bridges and plates that have been coated with anthracite ruthenium are there to be cherished by the wearer. 

Click, to see the large size. ▶ BIG FOTO    

Upon scrutiny of the motion works keen observers will be able to notice the Maison’s unique snailed diamantage coquille motif and the thorough polishing featuring sharp inner angles of the components.

Signature Minerva Movement Design

The movement components are designed with signature traits of Minerva design, such as the distinctive Minerva arrow and the Maison’s “V”-shaped bridge are also on display. 

Click, to see the large size. ▶ BIG FOTO  

 The Minerva arrow is a tribute to the Roman Goddess who is always depicted with her arrow-tipped staff in hand, and the unusual “V”-shaped bridge comes from the view of the mountains seen from the watchmakers’ window in Villeret, a sight that has been a constant since the founding of the workshop in 1858.

A Timepiece Without Distractions

Consistent with the high-level finishing and complicated caliber design, the timepiece fosters a top-notch functional appeal as well. Unrivaled attention to detail has been paid to the chronograph time indications with an open-worked 30-minute chronograph counter, an open-worked small seconds display, and elegant hands and indexes featuring Super-LumiNova® coatings for better legibility.

This Montblanc Unveiled Secret Minerva Monopusher Chronograph Limited Edition launched at Watches and Wonders celebrates the heritage crafts while presenting the same in a more contemporary package for watch aficionados to cherish!

About Minerva

Founded in 1858 in the Swiss Jura valley of Villeret, the Manufacture Minerva has been in continuous operation for almost 165 years. Specialising in chronographs and sports counters, Minerva’s precision has received numerous world distinctions over the years. What sets Minerva movements apart is that each movement is assembled from start to finish by the same watchmaker. There are also a number of important details that you will only find in a Minerva movement: an incredible level of finishing, with bridges and baseplates in traditional German silver; a Minerva arrow that pays tribute to the Roman Goddess who is always depicted with her arrow-tipped staff in hand; an unusual “V”-shaped bridge inspired from the view of the mountains seen from the watchmakers’ window in Villeret; in-house hairsprings; and a special snail finishing.

Both Montblanc and Minerva are dedicated to pushing the limits of aesthetic and technical excellence. They are connected by fine craftsmanship, they are connected by mountains and valleys. They are connected by a quest for perfection.
