The 5th generation Ingenieur SL has a lot going on and was in production between 1993 and 2001. Design uniformity in the integrated bracelet and tonneau case, attractive details like the drilled portholes on stainless steel bezel and gold hands and indices.

The classic IWC signature on the glossy black 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 the original box and papers from first purchase in July 2000.
