For those who wants to know how much is the Grand Seiko then, in1965, Seiko´s first model diver (62MAS) sold for 13,000JPY, approximately half the monthly wage of a Japanese college graduate. By way of comparison, the precursor sport/waterproof 50m Silver Wave 6201B (1960) cost 11,000JPY while its lower-spec successor, the 6601-7990 30m Sportsmatic Silverwave sports diver cost about 8,200JPY. At this same time the GS 5722 cost a breath-taking 27000JPY, a full month wage of a Japanese college graduate.
