1858  

Split Second Chronograph Limited Edition 8

The Montblanc 1858 product line is inspired by the legendary Minerva professional watches from the 1920s and 1930s which were conceived for military use and exploration. Reinterpreting these legendary models, the Montblanc 1858 watches express the spirit of mountain exploration, embodying the modern trend of returning and reconnecting to nature.

For this year’s SIAR, Montblanc is unveiling the Montblanc 1858 Split Second Chronograph Limited Edition 8, which combines a 44-mm bronze case with a distinctive smoked-green dial crafted from nephrite jade, a first for the Maison.  Nephrite jade is one of two distinct mineral forms of this precious stone and is prized for its durability, toughness, translucency and lustre.

Inspired by the Mexican flag, the Nephrite jade green dial is paired with rose-gold-coloured elements and red accents that accentuate the vintage style, while also providing excellent readability of the complications both day and night.  An anti-magnetized treatment on the inside of the sapphire crystal allows for greater precision of the two chronograph seconds hands. The chronograph indications are displayed via a rose gold-coated central chronograph second hand, a white-coloured split second hand (to measure a second time interval) and a chronograph minute counter at three o'clock.

Following the design of the original Minerva timepiece, the Montblanc 1858 Split Second Chronograph Limited Edition 8 features a telemeter scale that runs around the dial, which was a common feature on the legendary Minerva chronographs. A telemeter makes it possible to measure the distance of a phenomenon, which is both visible and audible, like the lightning and thunder in a storm. The chronograph hand starts when the phenomenon is seen (lightning) and is stopped when the sound is heard (thunder). The position on the scale shows the distance in kilometres separating the phenomenon from the observer (or the user from the storm, in this example). Calibration is based on the speed at which sound travels through the air, which is approximately 340 meters per second or 1,115 feet per second.

The timepiece also features a tachymeter (base 1000) at the centre of the dial in a colimaçon, snail shape, which allows the user to measure a length of time up to three minutes (instead of one minute in a traditional tachymeter scale around the dial). The tachymeter scale is to show the speed of a moving object, such as a car, over a known distance, measured in miles or kilometres. As the moving car passes the starting-point of the measured course, the owner starts the chronograph hand and stops it as the car passes the finishing-point. The number indicated by the hand on the tachymeter scale represents the speed in kilometres or miles per hour.

It is combined with a complex “rattrapante” (split second) complication developed by the Montblanc engineers that allows the user to measure intermediate times without interrupting the ongoing measurement of a longer elapsing time. The “rattrapante” can be admired through the sapphire glass of the case back like on a traditional timepiece with such a function.

The Montblanc 1858 Split Second Chronograph Limited Edition 8 is equipped with the hand-crafted Manufacture monopusher chronograph calibre MB M16.31 that features two column wheels, horizontal coupling and a power reserve of 50 hours. The movement takes its inspiration from the original Minerva calibre 17.29, developed in the 1930s, that was used for both pocket watches and wristwatches.  This modern-day version is recognisable thanks to its beautiful hand-finishing such as Côtes de Genève stripes, inner angles, circular graining and bevelling as well as its fine details such as the recognizable Minerva arrow, a chronograph bridge shaped in the form of a “V”, and a large screwed balance that has a traditional frequency of 18,000 semi-oscillations per hour.

The timepiece features a matching green alligator strap with beige stitching that has been hand-crafted by the Richemont Pelletteria in Florence.

In order to guarantee the performance of the product line, the limited-edition timepieces undergo over 500 hours of simulated wear, with specific testing and controls under real-life conditions.

Guided by astronomy, the navigators from the past where faithfully accompanied by the stars and the moon during their quest of discovery. The new HM Perpetual Moon Aventurine is a tribute to these explorers. A new elegant high-precisely Moonphase for the modern adventurer. One of the biggest Moonphase in the market mixed with a beautiful blue Aventurine stone dial. A perfect mix between art and technical poetry.

The HM Perpetual Moon is a testament to Arnold & Son's tradition of watches with astronomical indications. Our timepieces in the Royal Collection demonstrate the brand's prowess in traditional watchmaking and classical decorative arts

In true Arnold & Son tradition, the brand has released one of the most alluring and precise moonphase watches. The HM Perpetual Moon, with one of the biggest moonphase apertures on the market, rightfully joins the Arnold & Son Royal Collection. The Royal Collection is inspired by the timepieces created in the early part of John Arnold's life, and pay tribute to the watches he produced for King George III and members of the royal court. The timepieces in the Royal Collection demonstrate the brand's prowess in traditional watchmaking and classical decorative arts.

The exceptional perpetual moonphase indication of this watch is a marvel in many ways. From the aesthetic side, the 29 mm moonphase disc, which runs from 10 to 2 o'clock on the dial, reveals one of the largest moons on the market - with a diameter of 11.2 mm for the moon alone. Additionally, this large moon is one of the most visually stunning recreations of the moon because it is a three-dimensional sculptured moon that was first hand-engraved and then duplicated for the series. The sculptured moon is then inserted into the disc.

From the technical side, in addition to the HM Perpetual Moon being so precise, it is also an intriguing complication in that it is not simply a module added to the movement, but, in fact, is fully integrated into the calibre. The watch also has a unique easy-to-set feature thanks to the ingenious addition of a second moon indication installed at the back of the movement. This second moon display, visible via a transparent case back, features a graduated dial and a pointer hand that allows for a more exact setting.

The multiple technological advancements in the calibre make this timepiece truly outstanding. To further underscore that, the entire rhodium treated nickel-silver movement features hand finishing indicative of the finest Haute Horlogerie timepieces, including manually chamfered bridges with polished edges, fine circular graining with polished edges and Côtes de Genève rayonnantes, and blued screws. The timepiece naturally features an anti-reflective sapphire crystal and case back to view the meticulous details.

Taking the HM Perpetual Moon to higher heights, Arnold & Son offers three very distinct versions for today's discerning clientele. The Elegant model is created in 18-carat red gold with an incredible blue guilloché dial in a stylized sunray pattern, blue guilloché moon disc with golden stars and the hand-engraved moon. The Classic model, also crafted in 18-carat red gold, features a cream-colored dial with a blue guilloché moon disc with golden stars and the hand-engraved moon.
