The production of Air-King started somewhere around World War II, one of the longest production runs for Rolex. Though it stopped for two years, between 2014-2016, when it came back it somewhat changed its looks. From white dial to black one, from no numbers to Arabic ones. But these changes haven’t been for the worse, but on the contrary. It added so much value due to modern adaptation. Distinctive characteristics are the prominent minute scale and large 3, 6 and 9 numerals marking the hours, both useful for navigational time readings.
