History
Introduced in 1971, the reference 5626-7110 represented a major redesign of the earlier standard King Seiko 5626-7000. The watch features a sophisticated monobloc case design equipped with an external regulating screw. Early production models are particularly notable for featuring the gold medallion on the caseback, a detail that was replaced by a simple engraving in later 1972 models. The caliber 5626 inside is a celebrated hi-beat movement, representing the mechanical precision of Seiko during the era.
