For sale is my IWC 666AD caliber 8531 in working condition and with a really nice sharp case. The crystal is also intact on this one with the cyclops, usually these have been replaced at some time. The case is in excellent condition with sharp edges and lugs and the original brushing intact. The dial is in good original condition with intact lume plots. Often these fall off on these models. Text is sharp and well defined, not refinished. Subtle spotting is seen through the dial. The hands are also nicely aged and with uv the lume all matches and drops off evenly. The crown, case back, and faraday cage are all original and intact. Overall a nice example of an original 666ad. Will come on black calf strap. Asking 2950 USD shipped two day in the US. International shipping at cost. Photos:
