Only Watch Partnership
Now presenting its 7th Edition, Only Watch is a biennale auction of unique timepieces that has raised over 25 million Euros to date. Under the patronage of HSH Prince Albert II of Monaco and following the initiative of Luc Pettavino, President of the Association Monégasque contre les Myopathies, Only Watch is an international watchmaking charity event. All of the funds collected from the sale of the watches are donated in their entirety to scientific and medical research. The exclusive watches will embark on a world tour starting in the charity’s hometown of Monaco, and then continuing to Asia, the Gulf, the United States and Europe, before the final auction in Geneva on November 11th 2017.
Montblanc 1858 Chronograph Tachymeter Unique Piece Only Watch’17
Montblanc’s watchmaking expertise goes back to 1858, the year Minerva was founded in Villeret, Switzerland. Since its inception, the Manufacture has been renowned as one of Switzerland’s most revered specialists in chronometric functions for precise time measuring. Over the last decade, Montblanc has been exploring Minerva's incredible heritage, finding inspiration in historical functions, mechanics and design codes.
Inspired by the famous Minerva chronographs from the 1930s, the Montblanc 1858 Chronograph Tachymeter Unique Piece Only Watch’17 continues this horological journey by capturing the spirit of Montblanc’s past in a new and contemporary way. Paying tribute to the Montblanc 1858 Chronograph Tachymeter Blue Limited Edition 100, which won the prestigious Grand Prix d’horlogerie of Geneva 2016 as the best Chronograph, the timepiece features the traditional manual monopusher chronograph movement, the calibre MB M16.29; a distinct bronze case that has been combined for the very first time within the Montblanc Collection with a vintage green dial and a matching green alligator strap – making it truly special. “Montblanc is pleased to contribute a timepiece to Only Watch to help further research into Duchenne muscular dystrophy and help those suffering from this illness all over the world,” shares Nicolas Baretzki, Montblanc CEO.
Turning to bronze
The choice of a 44 mm bronze case enhances the vintage design of the timepiece.
Through this metal, Montblanc combines traditional Swiss artisanal watchmaking with a genuine material from watchmaking history. Particular attention has been paid to researching the perfect alloy of bronze that will evolve with its owner by developing its own unique, uniform and attractive patina over the years. The subtle changing colour of the case further enriches the appeal of this unique piece.
The historical design codes taken from the original 1930s Minerva chronograph include large cathedral hands with a cloisonné design filled with beige Super-LumiNova®, luminescent Arabic numerals that have been highlighted by the gradation of the green dial, a vintage shaped crown and a classic minute railway track. Other design details include the original Montblanc logo from the 1930s era with its historical font and emblem of the Mont Blanc Mountain in the centre, along with a green alligator strap that was made by the artisans at the Montblanc Pelletteria in Florence. The strap is also fitted with a satinated bronze-plated buckle that also complements the overall design.
The heart of the timepiece
At the heart of the timepiece lies the traditional manual monopusher chronograph, the MB M16.29, with a column wheel mechanism, horizontal coupling, chronograph bridge in a 'V' shape, a large screwed balance wheel with a frequency of 18,000 semi oscillations per hour and a power reserve of 50 hours. This in-house chronograph has been entirely handcrafted at the Montblanc Manufacture in Villeret and is a sight of unparalleled beauty thanks to its finishing. Designed in a large 'pocket watch' style, the calibre MB M16.29 has been inspired by the original calibre 17.29 designed for pocket watches and wristwatches in the 1930s. This new version uses almost the same shape of components as the calibre 17.29, but features different finishings, such as inside angles, Côtes de Genève stripes and circular graining. The Calibre MB M16.29 bears red gold-coloured components, offering a look that matches the bronze material and vintage appeal of the timepiece perfectly. As with all the historical calibres, one of the movement’s components is shaped into the form of the Minerva arrow to pay tribute to the Manufacture's heritage.
The chronograph indications are displayed via a central chronograph seconds hand and a chronograph minute counter at three o'clock. Other indications on the dial include a tachymeter scale that runs around the dial and a small seconds’ counter at nine o'clock.
This unique piece is completed with a non-allergenic, titanium bronze-plated case back that has been specially engraved with the inscription Unique Piece – Only Watch’17, making it a true collector’s piece.
