Here is a very uncommon ref. 5701, Rolex Oyster Perpetual Air-King-Date Precision dating to 1965. This is an uncommon 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 feature. The 35mm stainless steel and gold, fluted-bezel case is in very good shape and on the wrist, look close to new! The caliber 1520 Rolex automatic movement just had a cleaning and overhaul by our Rolex-trained and authorized watchmaker and is keeping excellent time. The original dial displays a suntan that appears very even with the naked eye.
