More about IWC IW503501 Portuguese Annual Calendar SS Silver Dial

This is a stainless steel IWC Portuguese Annual Calendar IW503501. It has an alligator leather strap with a stainless deployant buckle, and a scratch resistant, arched-edge sapphire crystal with anti-reflective coatings. There is a screw-down exhibition sapphire display case back. The 44.2mm diameter solid three-body case, downturned lugs, and stepped rounded bezel are polished. The dial is silver with applied silver Arabic numeral hour markers, baton indices, steel feuille hands, and an outer railway-style minute ring. The annual calendar is displayed in an arch with three aperture windows at the 12 o'clock position, including the month, date, and day.
