Launched last year to great (even personal) fanfare, the Seiko Prospex "First Diver's Modern Re-Interpretation" is a 40.5mm spin on the brand's first dive watch, the 62MAS. Initially offered in four versions including one 5,500-unit limited edition (the link blue dial SPB149), the 140th Anniversary link limited edition (reference SPB213) sticks to the same format but offers a white dial link and a lovely medium-blue bezel along with a not-so-limited production of 6,000 units.
