More evidence the 1960’s and 1970’s were a golden era for Seiko is evident in its long-running 700X line, such as the 1973 example here.  The 700X line debuted in 1969 - making this one here one of the first produced - and was made until the 1990’s, when it was replaced by Seiko’s famed 7S26 line. 


The 7005 line was a midrange offering, which featured Seiko’s Magic Lever winding system, and allowed the automatic rotor to gather energy in a bi-directional fashion.  Of note, the earlier versions of the 7005 line, like this one, did not suffer from plastic parts (which caused later models to suffer in terms of accuracy), and was all metal in construction.


The 700X line came in several sub-variants, which included the 7005 here, as well as the 7002, 7006, and 7009, all of which were almost identical and shared numerous parts in common (which also makes watch servicing cheaper).  The 7005 was date only, the 7009 a day/date, and the 7002A date only and with a different auto winding weight.  


When comparing the 7S26 to the 7005, the lineage is more than a bit obvious.  That said, there remains a lot in favor of the 7005, as the calendar mechanism of the 7005/9 was superior in design and construction and the overall quality of finish on the 7S26 is substantially lower than its predecessors.  


This 7005 comes with a leather strap, nylon NATO strap, spring bar tool, and hard plastic travel case.
