The Seiko Presage Style 60s ‘Ruby’ SRPH93J1 is a vintage-inspired men’s automatic wristwatch [Heur]. It pays tribute to the 1964 Crown Chronograph, Japan’s first wristwatch equipped with a stopwatch function [Heur]. While it captures the precise aesthetic of that historic timing piece, it functions purely as a standard time-and-date watch [Heur].
