MONTBLANC – 1858 The Unveiled Minerva Monopusher Chronograph 43mm Yellow Gold Limited Edition 2026
An expansive view of mechanical excellence
Minerva’s reversed movement timepiece is presented in a rich brown colourway and full-gold construction.
First introduced in 2023, Minerva The Unveiled Chronograph unveils the stunning complexity and meticulous hand-finishing of the movement on the front side of the watch. This full view is facilitated by the reverse-mounted movement, which exposes the bridges, levers and gears, as well as by the open-worked sapphire dial, which virtually disappears from view, and five apertures built into the mid-case.

Because the movement is built onto pillars, the lower plates are naturally illuminated through the mid-case apertures, which allows the eye to explore the intricate architecture of this calibre. To create even greater visual contrast, Minerva unveils a new limited edition version of the timepiece where the rear-mounted plates, as well as the signature V-shaped bridge up top, are coated in a rich brown colour, further matched by the brown semi-matte alligator strap. This reimagined colourway of the watch comes in a limitation 30 pieces. With monopusher functionality and full-gold construction, Minerva The Unveiled Chronograph extends Minerva’s long tradition of manufacturing mechanically and visually sophisticated chronographs cherished by discerning collectors.
A classic configuration reversed
Developing a reversed chronograph movement which places all chronograph and time-telling functions in their traditional locations, as well as having them spin clockwise, was a feat of modern watchmaking. The result is a fascinating view into the works, but also a familiar and legible layout.

The open-worked sapphire dial has been reduced to an outer ring, which secures the luminescent yellow gold hour markers, and three open rings across the horizontal axis. At 9 o’clock is the continually running small seconds hand in yellow gold with a small arrow tip.

Within the central ring, the cathedral hour hand, syringe minute hand (both luminescent) and chronograph seconds-hand are mounted on the main arbor, which extends up through the top-mounted V-shaped bridge in brown. At the 3 o’clock position is the chronograph’s 30-minute totaliser, its hand in the shape of Minerva’s arrow.
A solid gold case
The 43mm case is constructed in solid 18K yellow gold, and feature’s Minerva’s signature fluted bezel, which, along with the classically styled handset, harkens back to chronographs of the 1930s. Chamfered lugs reach downward to the brown-coloured alligator strap, while brushed and polished surfaces meet to form precision contours that spell out the subtle curvature of the lugs.

Especially unique here are the five apertures in the mid-case, which allow lateral views into the pillar-mounted movement, an angle from which one rarely gets to examine a movement.The caseback is in solid 18K yellow gold and displays a special laser engraving of the Minerva manufacture in Villeret, Switzerland, where it has stood since 1858.

The RFV logo with Minerva’s arrow, one of Minerva’s signatures, is also included here. Standing for Robert Frères Villeret, the logo had been used on watch cases and movements up into the early 20th century.
The chronographe calibre - in-house reverse
Crafted entirely in-house, the patented Calibre M17.26 is composed of 291 individual parts, and it uses 26 jewels to assure frictionless operation of the critical pivot joints in the chronograph. The monopusher functionality requires only that the user press the same button in the center of the crown to start, stop and reset the stopwatch. Precision is attained via a free-sprung balance wheel with an array of finely tuned regulating weights mounted to an in-house hairspring. Power reserve is 50 hours on a full wind, and the movement beats at traditional 18,000vph (2.5Hz).

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.
