There are totally four watches of IW503502, three of them are in white stainless steel, the other one has a rose gold case. I will take the stainless steel model with black leather strap for example. The case is made of solid 316L stainless steel, which is measured to be 44mm in diameter, case thickness is 14mm. Round case and thin bezel make the dial look bigger, this is the classic case design of most dress watches. As one of the most popular dress watches, IWC Portuguese has a simple case and elegant dial design. The front face of the lugs are polished, both sided faces of the case are brushed, the arc of the lugs is improved, it is closer to genuine. Case back is see-through sapphire crystal.
Let us see the dial first. It is in black white white markers and printings. Hands are completely different other IWC Mark series’. Have you noticed the hour hand, it is reverse. Hour markers use Arabic numbers except a big triangle mark at 12 o’clock. Date window is set at 3 o’clock, on the left side of the 3:00 hour marker. The dial also has other subtle difference if you compare Mark XI and Mark XVII or XVIII. Green nylon band is also one highlight. Nylon strap is a great match for the watch, it is perfectly in line with the military theme of the watch. One pair of distressed leather band could also create such effect, but a modern alligator leather strap will not.
