The reference 1680 was produced from 1969 to 1980. Collectors are especially interested in the watches which have the word "Submariner" in red. When this watch was made the examples with 660ft/200m on the dial targeted mainly the U.K. and North American markets, whereas examples with 200m/660ft were aimed at the rest of the world. Caliber 1575 is an improved version of the caliber 1570. However, the bridge of caliber 1575 is still engraved with the number 1570. For technical details see the Rolex Oyster Catalogue, R20.
