Iwc Ingenieur SL Black 1983

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, gold hands and indices, and matching date wheel.


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