Features stainless steel case with 18K white gold fluted bezel. 
Silver dial with pink hour marker indicators and Arabic numerals at 3,6,9 hour.
Has a polished fluted bezel.
It is 34mm in diameter and comes with an Oyster bracelet by default.
The Air-King does not have a Date.
In the 1970s, the Air-King was offered with a date (scarce!) and in gold & steel combinations. 
Those two variations likely ceased production since they are redundant next to the Date and Oyster Perpetual models.
This is an excellent mid-size Rolex, equally at home on a lady's wrist.
Automatic movement Caliber 3130 with a 42 hour power reserve.
COSC certified chronometer 
Various dial color options as well as hour marker variations were offered, so that some have Arabic or Roman numerals or a combination with stick index markers - even different colors on the markers. 
All-in-all this remains a Rolex, much beloved & always popular!
Water resistant to 100 meters / 330 feet
