In this new edition all the references of the Milgauss and Explorer I and II are treated in detail, even looking into those tiny features that, in today’s market, make a huge difference in price, such as, for example, graphics and the evolution of all types of dials. For the first time, we have clearly illustrated all the eleven types of reference 16570 dials and their respective watch value. Here you can also find the CHRONOLOGICAL PRODUCTION TABLE AS FROM 1953 and the TABLE OF ALPHANUMERIC CODES ON BRACELET CLASPS. Attached to the book are the updated estimates with the guide for a correct interpretation: The estimates refer exclusively to the watches published in this edition. The 2022 Rolex Retail Price in Italy is indicated in red. Factors, which determine the value of the published timepiece, are: – rarity – condition – warranty – kit of accessories – the correspondence of the period of the watch with its bracelet, dial, hands and bezel; – condition of its movement. If, instead of an estimate, we find ****, it means that the watch is so rare that has not had a valuation.
