Seiko Limited Edition TBS 2021-5600 Dodecagon Watch - 1980
Founder's Selection
" During the 1980s, Seiko explored bold, geometric case shapes and specialized commemorative commissions, demonstrating its mastery over high-precision quartz movements and avant-garde watch architecture for the Japanese domestic market.
Featuring a distinctive 12-sided (dodecagon) gold-tone case, this rare 1980 vintage model was produced as a limited edition for the Tokyo Broadcasting System (TBS) network, highlighted by the stylized "TBS" insignia below 12 o'clock. The crisp white dial is framed by black Roman numeral hour markers, an inner railway minute track, and gold-tone hands. Paired with ornate strap lugs and a black leather band, it offers a uniquely geometric, collectible piece of Japanese horological history. "
