Iwc Ingenieur SL Paper Graph Grey 1980s

The 2nd generation Ingenieur SL has a lot going on. Design uniformity in the integrated bracelet and tonneau case, attractive details like the drilled porthole bezel and gold hands and indices.

The classic IWC signature on the grey graph-paper dial adds a sort of studious sophistication to this decidedly luxury but accessible 1980s sport watch and the best part is that it comes in excellent condition.
