In 1965, Seiko introduced its, and Japan's, first-ever diver's watch, known to fans as the 62MAS. This example dates from 1967 and is in remarkable condition for its age, featuring the Dolphin motif to the case back and superb dial. This model was re-interpreted by Seiko in 2023 as part of its Save the Ocean initiative.
