Vintage Seiko Skyliner 6220-7990 Manual 21J Silver Radial Dial 31mm Watch Box

About this watch

A 1960s Seiko Skyliner, reference 6220-7990, powered by Seiko's hand-wound 21-jewel calibre 6220. The silver dial has an unusual minimalist design: fine black radial lines from the centre in place of hour markers, with the stylised "Seiko Skyliner" script, "21 Jewels" and the Diashock symbol at 4 o'clock, and slim silver baton hands with a central seconds hand. The round case sits within a sculpted, highly polished cushion-shaped steel case with an integrated expanding steel bracelet. The serial number 830608 dates it to March 1968. Supplied in a Seiko presentation box.

Brand heritage

Seiko traces its roots to 1881, when Kintaro Hattori opened his watch and jewellery shop in Tokyo, and has made its own movements in-house ever since. The Skyliner was Seiko's line of slim, hand-wound 21-jewel dress watches of the 1960s, built around the reliable calibre 6220 family and made in Japan.
