seiko seikomatic blue yacht j13023e 1960s Cal.3185 The same 18K white goldThis is a watch that is not seen very often the Seikomatic Blue Yacht. This model was only produced for only a year in 1961. The watch was rated as Standard Level Waterproof (30M) which is the first automatic watch with waterproof to 30m. This has an unusual swirl pattern to it that I have cannot remember seeing on other models. Also, the yacht engraves on caseback is only seen in this model.
