The 3rd generation Ingenieur SL has a lot going on. Design uniformity in the integrated bracelet and tonneau case, attractive details like the drilled portholes on 18k yellow gold bezel and gold hands and indices. It only was in production between 1985 and 1989 and produced only a few hundred times and there for is not seen everyday.
The classic IWC signature on the golden papergraph dial adds a sort of studious sophistication to this decidedly luxury but accessible sport watch and the best part is that it comes in excellent condition and as a full set with box and papers.
