King Seiko... the king of Seiko watches, the finest of all... I don't know whether this is correct, but I do have an impression King Seiko and Grand Seiko are the finest Seiko had to offer during the 1960-1970's. King Seiko (produced in Daini Seikosha) and Grand Seiko (produced in Suwa Seikosha) were competitive partner and rivals in producing high quality Seiko mechanical watch. For me both Grand Seiko and King Seiko are on the same pars but generally believe that Grand Seiko has the upper hand.
This is a 1968 King Seiko. The case and the crown are gold plated to 20 microns. The glass is acrylic. What amused me is that the second hand of this watch is orange in colour. I think it might not be original as the standard will be gold plated hands. This watch is utilising calibre 4402A. 4402A is a 25 jewels manual winding movement with hacking function. It is low beat movement. At the back case there is a gold emblem with Seiko wording.
