King Seiko Pocket/Necklace Watches
Case material: Silver 925. Case size: about 35mm x 40mm. Movement 5621A (with fine adjustment removed).
Róbert Sipos: "... there were also a large number of more form-breaking members in the family (although most of them appeared in the Vanac series). The most unique King Seikos include the four "necklace watches": 5621-5000, 5621-5010, 5621-5020, 5621-5030. These were made specifically for fashion purposes, their crowns were placed at the bottom, with a distinctive dial and unique (not waterproof at all) silver cases."
Antiwatchman: "Manufactured in June 1970 (estimated). The 925 silver case has a swan mark, that is, a Swiss Hallmark, on the inside of the case back, so either you dared to bring it to Switzerland for certification, or the case itself is made in Switzerland. Even so, it is a watch manufactured at an exorbitant cost. It is a kind of King Seiko, but it seems that it was set at a higher price than the 56 series Grand Seiko at that time."
