IWC Ingenieur SL Two Tone Papergraph 1986

The 2nd 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 1983 and 1985 and there for is not even everyday.

The classic IWC signature on the grey 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.
