History Introduced in the late 1960s, the Seiko Lord Matic line was positioned just below the Grand Seiko and King Seiko tiers, offering sophisticated movements and high-quality finishing. The caliber 5606 features both a hacking function and the ability to be hand-wound, and it served as the foundational architecture for higher-beat movements used in King Seiko and Grand Seiko models. This 1972 example clearly illustrates the bold design language and mechanical ambition of Seiko during a highly creative period in watchmaking. / Second Vintage SKU: SEI-LXX-0076
