This is an all original vintage 1972 ROLEX AIR-KING Date in steel and measuring 35mm. There are some minor marks from normal use on the case. The original dial is an unusual and pristine, Blue jean colour-is flawless with all lume plots intact. These AIR-KING DATES are the “hot ROLEX watch” at this time. This DATE variety of AIR-KING that was sold mainly in Canada and Commonwealth countries only. The date is the feature making it uncommon; as the regular and common AIR-KINGS do not have the date. The automatic winding ROLEX cal. 1520 movement was just cleaned and is accurate. I believe these watches will increase in value over time.
