The 6458-6020 JDM Diver is an interesting watch for three reasons. The first is that at 38mm it was smaller than most divers of the time, secondly it was only produced for the domestic market in Japan for less than a year between 1984/5 and the third is that Seiko gave it the status of 'Professional' and rated it to 200m. Little is known about the reason Seiko introduced this watch which had it's roots in the the 7548-7000, Seikos first attempt at a quartz powered dive watch that had a case size of 42mm. After the very short production run the 6458 was replaced in 1986 by the 7C43 which was also sized at 42mm. So with a mysterious less than one year production run and considered 'mid size' the 6458-6020 is interesting & fairly rare, especially in good condition. It's also the perfect option for anyone looking for a slightly smaller sized diver.
This watch dates from July 1985. Not pressure tested or guaranteed waterproof.
