Rolex Oyster Perpetual catalog from 2006. Reference: 300.06 USA. 44 pages with brand information and the line-up of timepieces from that time period, including GMT-Master II 16710, TT Sub 16613, Explorer II16570, ladies OP and DJ models and more. Printed in Switzerland. The outside cover has a pearly sheen to it with a green Rolex logo and golden coronet on the front and back. “Oyster Perpetual” is in raised lettering on the front. It measures about 5.75″ x 4″, 3.25mm thick, weighing 1.9 ounces. This booklet was NOS and in storage for many years, but unfortunately there is a scratch across the front cover – despite that blemish, it is still in very good condition overall and worthy of any Rolex collection.
