In workign order. In the 60'sSeiko had two distinct manufacturing facilities: Daini Seikosha (Tokyo) and Suwa Seikosha (Nagano).Grand Seiko?s initial release in 1960 was born out of the Suwa factory, while King Seiko hailed from the Daini factory the following year in 1961. Seikopitted one against theanother to encourage a healthy degree of competition, with some claiming thatthe two factories were in an all-out rivalry for survival. The truth is likely far much less sensational, and in all likelihood saw a degree of collaboration at times. Thiscollaboration brought innovation like the 4502 caliber movement in this King Seiko - being manually wound to provide a lower profile with a newly developed instant date change mechanism all with 36,000 beats per hour for greater accuracy.
