Description: Rolex Yacht-Master 40 Ref 16628 Pre-owned Rolex Yacht-Master 40 ref 16628 (1998) represents the very beginning of the Yacht-Master line, as the inaugural model that introduced the collection in the early 1990s. While it shares some DNA with the Submariner, the Yacht-Master was always positioned a bit differently. Less of a pure tool watch and more of a refined take on the sport category. This example is made entirely in 18k yellow gold from the case to the bracelet
