The Gyro Marvel was Seiko’s first independently developed automatic watch. It was introduced in 1959, as a subset of the Marvel Line. It is the first watch to adopt the magic lever system and it is also the first time a bearing is adopted for the rotor in a Seiko. These systems became the foundation of the Seiko automatic movements and were taken over to Suwa 62 system. Some have referred to this as “the ancestor/founder of the Seiko automatic movement.”
The Gyro Marvel’s caliber is based on the Marvel caliber and exist only in a 17j version. Like the Marvel, they formed Seiko's top watch line of watches during the late 1950’s. Sadly, the Gyro Marvel was relatively short lived and was replaced in Seiko’s lineup by the Seikomatic in 1960. The price of a Gyro Marvel in 1959 was ¥5,900.Special Dial (SD) - The eight-pointed star. This is on high end watches but with printed dials rather than applique.
