This Rolex Oyster Perpetual Air-King Super Precision is an uncommon vintage Rolex dating to 1958. This Air-King Super Precision was only produced for about four years. The caliber 1050 automatic butterfly rotor movement was just cleaned, overhauled, and is accurate. The very fine 34mm stainless steel case (of course) is original, with the 5500 reference. The original Super Precision dial is all original. This dial is really in wonderful shape, with only the slightest marks that are barely noticeable with the naked eye. These early Rolex Super Precision Air-Kings are becoming highly desired by collectors.
