The Legend Diver is Longines reaching back to a 1959 tool watch, and the defining feature is right there on the case: two crowns, no external bezel. The dive scale rides an internal rotating flange controlled by the upper crown, a design Longines used originally to protect the setting from knocks, and it gives the watch its clean, uncluttered silhouette. This is the 42mm steel version with the black lacquered dial, beige-toned Super-LumiNova markers and the date at 3, wearing on the matching steel bracelet with a triple folding clasp. Underneath is the caliber L888, an automatic built for Longines with a silicon balance spring for magnetic resistance and a full 72-hour reserve, and the case is rated to a serious 300m. It is a genuine dive watch with vintage bones, one of the most characterful sports pieces in the Longines catalog, and this one comes with its original box and papers, dated 2023.
