Rolex Oyster Perpetual vintage Air-King 5500 with the very rare “Herringbone Sector” Dial. 34mm stainless steel case, smooth bezel and ridiculously rare herringbone dial which features a ridge / grooved 3D dial with raised dagger head hour markers, 3,6, 9 Arabic numerals. Original sword shaped hands and steel blue’d seconds hand. Fitted to fold over oyster link bracelet with double folding clasp. Rolex Air-King 5500’s were made for over 35 years however in the first few years they were made with many unique and rare dial configurations until they were set to standard uniformed dials in the early 1960s. Our dial is arguably one of the rarest of the bunch with none on the market today with few known to existence. The 5500’s were produced with the 1520 / 1530 calibre movement, our watch is powered by the calibre 1530 movement. Our immaculate and original example was manufactured in 1958. 374*** serial.
