IWC Aquatimer ref. 1822 with complete set of papers in mint condition from 1983. The untouched case is showing next to no signs of wear. The dial and hands set are in mint condition and have developed a very nice patina. The watch will accompanied by the pictured paperwork and the original leather strap (good condition) with the original pin buckle. Service history is unknown, but my watchmaker hast just checked the movement (cal. 8541) and it is working perfect.
