This version of the Quai de L’lle Day Date & Power Reserve from Vacheron Constantin is a vision of complexity and strength. Its fortitude courses through the Titanium lugs, bezel and 41x44 case, as well as the scratch resistant sapphire crystal protecting the front and back. The dial is a deep well of intricacies. These include but are not limited to laser-engraved Day & Date alpha/numeric digits filled with white ink, Galvanic growth of nickel applied to the 3, 6, 9 and 12 markers, a metallization treatment creating white gold micro-text around the sub-dials, and a power reserve indicator located just above the 6. The dial is also covered with transparent film, in which a pattern of Maltese Crosses and concentric lines (doubling as a seconds track) mix with micro-characters only visible when viewed under UV light. The watch is also water-resistant for 30 meters, and has a black rubber band with deployment clasp. Then there’s the passport, an authenticating document employing all manner of specialized signatures, including line engraving, offset printing, invisible ink, optical variable ink, thermal printing, laser perforation, micro-printing and transvision. This passport is included with the manufacturer’s box and papers you will receive.
