Introduction This Seiko King Seiko 5626-7040 Hi-Beat Chronometer represents one of the finest achievements of Seiko’s mechanical era. Combining a precision high-frequency movement, certified chronometer accuracy, and elegant 1970s design, it is a highly desirable example for collectors of Japanese horology. Historical & Collector Value The King Seiko series stood alongside Grand Seiko as Seiko’s flagship mechanical line, created to compete with the best Swiss chronometers. The 5626 Hi-Beat movement (28,800 vph) is especially respected for its accuracy and durability, and chronometer-certified models are significantly rarer. The 7040 case design—with its clean, angular profile—captures the aesthetic philosophy of Seiko’s golden age of precision watchmaking.
