For the delight of those peering into the depths of the movement, this latest limited edition comes with a new movement, the Calibre MB M17.26.

Like the Calibre MB M16.26 that equipped the previous versions, this monopusher calibre has been flipped over to display all the mechanical action on the dial side of the watch. At first glance, the viewer may think it is a skeletonized movement, but a closer look reveals that this chronograph movement is on full display on the dial side of the watch.

In order to let the eye delve deeper into the movement and enjoy the craftsmanship of the individual components, the chronograph complication of the Calibre MB M17.26 has been constructed on pillars, allowing the light to flood in.

The chronograph bridge has also been put on top of the movement to highlight this distinctive component, the specific design of which was patented in 1912.

Adding another modern twist to the timepiece, the German silver plates and bridges have been colored in a contemporary blue, providing a contrast with the rest of the movement, yet matching the tone of the blue sfumato calf leather strap.

This new limited edition comes in a 43mm stainless steel case with an elegant horizontal satin finishing. It is fitted with a white gold fluted bezel that has been inspired by Minerva’s first fluted bezel dating back to 1927, adding a touch of finesse to the model.

Signature Minerva Movement Design

In keeping with all Montblanc’s complicated movements, 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.

No Distractions

Particular attention has been paid to the indications so that they don’t distract from the movement with a sapphire crystal dial, an open-worked 30-minute chronograph counter, an open-worked small seconds display, and elegant hands and indexes that have been created with Super-LumiNova® for enhanced legibility.

This new Montblanc Unveiled Minerva Monopusher Chronograph Limited Edition of 100 pieces combines tradition with a contemporary design thanks to the functionality of a monopusher chronograph and a new blue aesthetic that can be admired through numerous sapphire openings all around the case.

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.

MONTBLANC – 1858 The Unveiled Timekeeper Minerva Chronograph Edition

Montblanc’s bezel-activated Unveiled Timekeeper chronograph gets a new look

 

Following the launch of the Montblanc Unveiled Timekeeper in 2023, the Maison is introducing a new limited edition in distressed steel with a grey aesthetic. 

 

  Click, to see the large size. ▶ BIG FOTO   

Based on a historical calibre from 1923, Montblanc’s Unveiled Timekeeper Minerva has rethought the way we record elapsed time: all the traditional Minerva design codes and watchmaking finishes are present, and yet there is no chronograph pushers to activate the chronograph.

The Montblanc Chronograph

Montblanc’s chronograph story began in 1858 when Charles-Yvan Robert founded a watch workshop in the Saint-Imier valley. As early as the 1880s, the Minerva Manufacture in Villeret had already gained international recognition for its precise timekeepers. 

Click, to see the large size. ▶ BIG FOTO

In 1909, Minerva started to develop chronographs, quickly becoming a specialist in the fabrication of professional watches and stopwatches, and in 1923, it unveiled its first manually wound monopusher chronograph dedicated to wristwatches.

   Today, Montblanc continues the Minerva chronograph legacy with the Unveiled Timekeeper, transforming this much-loved complication from the past to the present through design and technical expertise.

The Story of the White Gold Fluted Bezel

In 1927, Minerva was among the first manufactures to make a fluted bezel as well as an internal countdown rotating bezel. This was followed in 1939 by its first wristwatch chronograph with an external rotating bezel and a reset function.

 In 2022, the Maison unveiled the 👉 1858 Minerva Monopusher Chronograph Red Arrow LE88 inspired by these rare external rotating bezel models. The key elements from the past included a fluted bezel, now in white gold, and Minerva’s recognizable red arrow that allowed a quick and easy reading of elapsed time.

Following the two limited editions released last year – one in stainless steel and the other in Lime Gold – Montblanc unveils a new edition that is housed in a 42.5mm contemporary distressed steel case. 

 

  Click, to see the large size. ▶ BIG FOTO   

This special finish is achieved by treating the stainless-steel case with a black coating. It is then manually washed and brushed with quartzite from the Mont Blanc mountain and limestone from the “V”-shaped mountain opposite the Villeret manufacture, called La Combe Grède, bringing the mountain and valley together. Thanks to this special treatment, each timepiece in this 100-piece limited edition gets its very own patina and singular appearance.

The distressed stainless steel case is dressed with an 18K white gold bezel, in keeping with current Minerva timepieces, while the grey dial takes its inspiration from Minerva chronographs from between the 1940s and 1960s.

Staying faithful to these historical pieces, this new edition comes with sunray finishing; luminescent hands, numerals, and indexes; elegant subdials; tachymetre scales (with a base of 1000m, 400m, and 200m); and white indications for easy reading. 

 

Click, to see the large size. ▶ BIG 

The new edition also comes fitted with a grey interchangeable calf leather strap with alligator print.

Calibre MB M13.21

The Calibre MB M13.21 is the latest version of the historical Calibre 13.20 that was launched over 100 years ago. The Calibre MB M13.21 is a hand-finished, manually wound movement with a 60-hour power reserve. 

Click, to see the large size. ▶ BIG FOTO

 The chronograph seconds are indicated with a contrasting blue-colored chronograph seconds hand with the Minerva arrow as the counterweight, while a 30-minute chronograph counter is positioned at three o’clock, and a small seconds’ indication balances the dial at nine o’clock. All the chronograph hands are in blue to provide an elegant visual contrast with the grey dial and create a clear distinction with the white indications of the time display.

How does the chronograph function works?

The new Montblanc Unveiled Timekeeper Minerva takes the fluted bezel from the 1858 Minerva Monopusher Chronograph Red Arrow and turns it into a chronograph function, marking the first time in Montblanc’s watchmaking repertoire it has been possible to activate a chronograph without having to press on a pusher.

  Click, to see the large size. ▶ BIG FOTO   

Thanks to an innovative mechanical function, the Unveiled Timekeeper Minerva chronograph is activated via its elegant 18K gold fluted bezel, which has been refined even further in this new edition, and defines all new timepieces crafted at the Manufacture in Villeret. Just rotating the bezel clockwise with one click will start the chronograph, a second click will stop it, and a third click will reset it, transforming the way a chronograph has traditionally worked. The bezel has 30 jumps/steps per whole turn, meaning that it can time 10 separate events in one complete turn.  

 

  Click, to see the large size. ▶ BIG FOTO   

Montblanc is one of the few watchmaking companies to have developed such a system and has filed several patent applications for it. This hidden feature respects the beauty of the historical calibre, while incorporating modern-day know-how to create a truly contemporary timepiece.

A Caseback Paying Tribute to the Minerva Legacy

The Montblanc Unveiled Timekeeper Minerva is completed with a caseback that tells the complete story of Minerva, starting with the name of the collection and the date of birth of the Minerva Manufacture at six o’clock. On an inner ring, key dates from the Minerva chronograph story are separated by little stars from the original Minerva logo, with the Minerva arrow at 12 o’clock. These key dates include:

• 1887 – Minerva brand and arrow symbol registered on July 30th, 1887.
• 1908 – Development of the first Manufacture chronograph movement (19/9CH) for pocket watches.
• 1912 – The Minerva V-shaped chronograph bridge is patented on April 10th.
• 1920 – Development of the Manufacture chronograph Calibre 13.20 for wristwatches.

• 2023 – Launch of the chronograph function through the bezel.

Through the caseback, more than 165 years of watchmaking novelties are documented, right up to the present day with the introduction of Montblanc Unveiled Timekeeper Minerva Limited Editions.

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. 

 

  Click, to see the large size. ▶ BIG FOTO 

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. 

 

  Click, to see the large size. ▶ BIG FOTO 

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.
