Vacheron Constantin has opted for an exclusive model from its Quai de l'Ile watch line to be unveiled at the Only Watch 2009 charity auction that will take place in Monaco.
Held for the third time, this event brings together a variety of unique timepieces by the world famous watch-making houses. The entries will be auctioned without a reserve price and all funds realized from the sale will directly aid research efforts for Duchenne Muscular Dystrophy.
The Vacheron Constantin exclusive timekeeping companion, the Quai de l'Ile watch, intended for the Only Watch 2009 charity auction, is the first model from the Quai de l'Ile watch collection with the case demonstrating a unique blend of metals. To manufacture this one-of-a-kind timepiece
, Vacheron Constantin used tantalum, quite a difficult and rare material, which is an absolute newcomer to the field of watchmaking.
Tantalum, standing out due to its weight, extremely attractive deep grey color, as well as its distinctive hardness, demands diamond cutting processes to take an exact shape of a timepiece case, and quickly requires a steep toll on the different cutting tools. The complex case composed of seven parts is mostly manufactured from tantalum with the flank components made of palladium, a metal which belongs to the platinum family.
The most complex and progressive dials are a key focal point of Vacheron Constantin's Quai de L'Ile timepieces. They include a number of security codings, created by a Swiss firm famous for its anti-counterfeiting techniques, as well as embellishments on passports and bank notes. The codings in question can be either always visible or noticeable in special light conditions.
The dials also demonstrate such elements as Vacheron Constantin's Maltese cross symbol and the bold numbers at 12, 3, 6, and 9, imprinted into the sapphire crystal by means of an exceptional galvanic process.
An extra detail added exclusively to the Only Watch 2009 edition is the text in tiny letters, which has been etched by laser around the circumference of the date disc. The inscription reads - "Monaco, September 24th 2009. Hand in hand with the Association Monegasque contre les Myopathies, Vacheron Constantin supports scientific and medical research to provide children with Duchenne Muscular Dystrophy a better quality of life”.
A red minute track, that symbolizes the colors of the Only Watch charity action, is performed by means of an engraving process with the paint applied afterwards. The dial’s central section reveals an engraving of the Only Watch symbol. When illuminated it acquires a three-dimensional look.
The Vacheron Constantin Quai de l'Ile watch intended solely for "Only Watch 2009" is powered by the in-house Vacheron Constantin 2460H, an automatic winding caliber with a date and sweep seconds function, alongside with hours and minutes. The movement features a balance wheel moving back and forth at 28,800 vibrations per hour and a power reserve of 43 hours.
The luxurious embellishments on the bridges and mainplate, featuring a ruthenium finish, and 22K gold central rotor with a hobnail pattern, just as well ruthenium-finished, are visible through a sapphire crystal case-back display.
The Geneva Seal hallmark, exposed on the bridge confirms the caliber's construction and embellishment to be in full conformity with the norms of conventional Genevan Haute Horlogerie.
This very model, reviewed by Watches.InfoNIAC.com, along with other timepieces, produced especially for the Only Watch 2009 charity auction, will go on a world tour under the auspices of Patrizzi & Co Auctioneers. The tour will start in Shanghai on the 29th-30th of July. Then, the items will be exhibited for viewing sessions in Geneva, London, New York City, Milan, and finally in Monaco.
