IWC Portuguese 7 Day Automatic Black Dial, Model IW5007-03

Never Worn with box and papers as shown

IWC Portuguese Automatic 7 Day Watch, IWC IW5007-03, All Stainless Steel Watch, Black Dial Watch, Silver colored Hands & Markers, With its 42.3 mm diameter case (houses the largest automatic movement available on the world market). The IWC calibre 5010, has been adapted for more slender wrists, while retaining the classical appearance of the legendary original Portuguese first made in the 1930s. The appliquéd Arabic numerals, railway-style minute chapter ring and slim, swallow-style hands, give this watch tons of character. An exclusive IWC Pellaton winding system, classical small seconds hand and seven-day power reserve display make it unique. Together with other new and more advanced features such as the convex, coated sapphire glass, the two-piece case or the back with its screw thread and sapphire glass, the Portuguese Automatic is the watch that would be developed in Schaffhausen if those two Portuguese businessmen were to drop in today with a request for an unusually large and precise wristwatch. This model comes on a black alligator IWC strap mounted on a folding deployant IWC brushed stainless steel buckle.
