The Quai de L’lle series from Vacheron Constantin offers multi-faceted timepieces of uncompromising function and style, and a perfect example is the 85050/000R-9340. 18K Rose Gold shapes the lugs, bezel and 41x41 skeleton case. Inside is the Calibre 2475sc automatic movement with 43-hour power reserve. Your gaze could drown in this dial’s depths, which are protected behind lightly tinted semi-transparent sapphire crystal. The day & date sub-dials and many other alpha/numeric indexes are laser-engraved and filled with black ink. A fine application of white gold micro-text is set around the sub-dials, and the pronounced Arabic numbers at 3, 6, 9 and 12 are the result of “Galvanic growth of nickel” processing. The power reserve indicator is located above the 6. A transparent film covering the glass holds details that are visible only in UV light, which include micro-characters amidst a pattern of Maltese Crosses and concentric circles, and these double as a seconds track. The watch has a brown alligator band with deployment clasp and is waterproof up to 30 meters. This watch also comes with its very own passport, and authentication is secured through use of invisible ink, line engraving, offset printing, hot stamping, optical variable ink, laser perforation and other specialized treatments. The passport is included with the manufacturer’s box & papers you'll receive.
