http://www.thewatchbox.com Do you want a single watch that takes the place of five? Good: IWC has your number with the DaVinci Perpetual Calendar Chronograph 3758-03. Produced for only three years from 2004-2006, this rare reference is an outstanding example of an IWC watch that offers everyday usability AND watchmaking chops rarely seen outside the flagship factory boutiques of haut-de-gamme brands. With the kind of compound complexity normally reserved for watches with names like Patek Philippe, Vacheron Constantin, Blancpain, and Lange, the DaVinci brings complicated watchmaking into the realm of practicality and affordability. Want an automatic-winding chronograph? With a moon phase? And a perpetual calendar... with day, date, month, year, decade, and century indications? IWC your number with the DaVinci Perpetual Calendar Chronograph 3758-03. As long as the name is, that's how much feature content the owner of this watch will enjoy. How many other watches combine the practicality of a chronograph, the refinement of a comprehensive perpetual calendar, and the romantic beauty of a moon phase? Not many under $100,000... And the IWC DaVinci Perpetual Calendar Chronograph wears like a modern sports watch. Its robust 41.5mm stainless steel case is sports-watch rugged, and wearing it entails none of the mortal fear of cufflinks and seatbelt buckles that hounds owners of soft precious metal watches. Robust hinge lugs increase the wrist presence and broad-shouldered stance of the DaVinci Perpetual Chronograph. These vintage-style appurtenances remove the unsightly gap between the linear strap terminus and the curved flank of the case; they also aid ergonomics by enabling the strap to pull down at acute angles in order to ensure a secure fit on smaller wrists. The combination of a silver dial, highly legible Arabic numerals, a sturdy steel case, and a rugged black alligator strap means that the DaVinci Perpetual Calendar Chronograph 3758-03 is ready to follow its owner everywhere except the swimming pool. Realistically, that's your cue to strap on an IWC Aquatimer, because with a watch as versatile and fully loaded as this DaVinci, the rest of your collection might be left fighting for scarce wrist time.
