The case, in 18kt red gold, measures 44mm x 13.1mm. It has an AR-coated sapphire crystal, a sapphire display back, and it is water resistant to 30 meters. The crown is 18kt red gold with a Montblanc emblem in raised relief and the cronograph monopusher is integrated into the crown.
Movement is the Swiss manual-wind Montblanc by Minverva in-house caliber MB M16.29 with 22 jewels, 18,000 vph and a power reserve of 50 hours. It is a monopusher chronograph with column-wheel and horizontal coupling. It is made of Rhodium-plated German silver with circular graining on both sides, the bridges are Rhodium-plated German silver with Côtes de Genève decoration and a balance spring with Phillips terminal curve. The going-train is gold-plated, with faceted arms, and diamond-polished surfaces. Functions are: central hours and minutes, small seconds at 9 o'clock. Chronograph's elapsed-seconds hand in the center of the dial, counter for 30 elapsed minutes at 3 o'clock and a tachymeter scale.
The Montblanc 1858 collection, unveiled at SIAR 2015, pays tribute to the manufacture founded under the name Minerva by introducing contemporary timepieces quoting vintage lines and being inspired by chronometer watches created throughout its 157-year history. The monopusher chronograph developed by the manufacture during the 1930s to meet the needs for precise timekeeping has served as a guide for developing the new Montblanc 1858 Chronograph Tachymeter chronograph.
The Minerva Heritage
The prestigious Minerva manufacture, founded in Villeret in the Saint-Imier valley in 1858, is now an integral part of the Montblanc watchmaking manufacture. It is recognised in the profession as one of the great specialists in developing chronographs and sports counters that can measure tiny fractions of time with chronometric precision. The 13.20 calibre launched at the start of the 1920s is one of the emblematic creations of Villeret, and has become one of the foremost mechanical chronograph movements specially developed for wristwatches. The mechanical counter, accurate to a hundredth of second, which was unveiled in 1936, is also of note. This passion for accurately measuring time, combined with perfect mastery of the various watchmaking frequencies and its ability to make its own balance wheels and balance springs, enabled Minerva to demonstrate its expertise in the field of timekeeping for demanding professionals. Montblanc is proud of this heritage, and is now continuing in this tradition by developing new high-quality calibres, made using the same traditional methods that Montblanc has always been keen to respect.
An Exceptional Manufacture Calibre
The calibre of the monopusher chronograph with an MB M16.29 hand-wound mechanism is the same size as that of a pocket-watch visible through the transparent sapphire case back and was inspired by the original chronograph movement, the 17.29 calibre, designed by Minerva in 1929. Consequently, it has components with many similarities. Just like the historic chronograph that served as the model for the creation of this contemporary, vintage-style product, it has a column-wheel activated by the single push-piece that is built into the winding crown. Through the transparent case back, it is also possible to see the iconic engraved "V" chronograph bridge, which has been protected by Minerva since 1912. All the components, including the cock of the large screw-regulated balance wheel for fine adjustment referred to as the "swan's neck", have a Geneva ribbing finish and edges with a large number of re-entrant angles hand-bevelled in the finest tradition of haute horlogerie. The horizontal coupling in this classic construction is combined with a lever that holds the chronograph's hammers, and is finished off with a little arrow, the visual signature of Minerva.

Montblanc 1858 Small Second Special Edition (Ident. 113860)
The Montblanc 1858 collection launched at SIAR 2015 also features a stainless steel, 44 mm-diameter model. This contemporary interpretation, in a design that extrapolates the codes of the historical chronographs produced by Minerva, indicates the hours and minutes, with direct-drive small seconds at 6 o'clock. Just like the models of the past, this creation operated by a hand-wound calibre has a bevelled winding crown that is ideally proportioned for everyday use. In the same vein, its fine, curved horns, designed to follow the natural curvature of the wrist, make this creation, with a design that is both pure and yet strong, particularly pleasant to wear. This new vintage-style watch features a black alligator-skin strap with ecru saddle stitching, fastened at the wrist with a stainless steel pin buckle. It is a limited edition of 858 pieces, paying tribute to the birthday of Minerva in 1858.
