Rolex Submariner

Nearly a decade later, Rolex made enough of a change to the Rolex Submariner ref. 14060 to warrant adding a suffix to its reference number, but not one big enough to merit an entirely new number altogether. The reference 14060M (with the ‘M’ standing for “modified”) was released in 1999 and fitted a revised movement, the Caliber 3130. The no-date version of the base Cal. 3135 which had been powering the Submariner Date series since 1988, the Cal. 3130 brought with it many of the elements missing from the previous iteration.
