+====== Seiko 5600 ======
+[[Suwa Seikosha]] produced the **5600** series of high-end [[automatic]] watch movements for [[Seiko]] in the 1960's and 1970's.
+This line was used in various [[Seiko Lord Matic|Lord Matic]], [[King Seiko]], and [[Grand Seiko]] models from [[1968]] through [[1976]]. It appeared first in the 1968 Lord Marvel, next in 1969 in the [[King Seiko 56KS]], and finally in 1970 in the [[Grand Seiko 56GS]]. It was also used in two other Seiko models - the Seiko Duotime and Seiko Chronometer.
+Unlike previous Grand Seiko movements, production of Calibre 5600 was highly automated. This made the movements cheaper and helps to this day since parts are more plentiful. But the speed of the movement was reduced from "Hi-Beat" 36,000 A/h of its predecessors.
+The **5600** family was introduced in [[1968]] for the Lord Matic and first appeared [[King Seiko 56KS|in King Seiko guise]] the following year. This was the first Suwa movement used in the Daini King Seiko line.
