Air-King-Date models are very common to Canada and other Commonwealth Countries but Coca-Cola was gifting them in Canada after 25 years of service and this is one of them. The watch is in overall good condition with normal wear for a 50 years old watch. These came with a stainless steel bracelet in 95% of cases that I have seen/owned so far. The watch has been polished before and bracelet is dated Z1, 1997.
