The 6218 movements an automatic, 35 jewel, 18,000bph, hacking calibre based on the 62xx platform that powered everything from Seikos World Time and their first dive watch, through to the Grand Seikos of the era. Both the 57GS/43999, 6218 and 62GS have 35 or 39 jewel movements and are all examples where jewels were added to stop what has been translated from the Japanese as the shake fall problem with the datewheel. This 1965 example is in lovely original condition.
Stainless steel case is in very nice condition with signs of ages. It measures 37mm without the recessed crown X 44mm which is quite large for the a 60's watch. The crown on the backcase can still be seen but as many Seiko watches from de 60's, it has nearly been erased by the years.This is an original Seiko 330T06AN, the exact correct ref for this case.

Silver indexes and hands are, as you can see on the photos, absolutely free of any defect. Quickset date is working turning the crown pulled on its first position, day can be set using hour setting between 21h and 24h.
