History
The Seiko Lord Matic series was introduced in the late nineteen sixties as a premium offering positioned just below the King Seiko and Grand Seiko lines. Powered by the sophisticated 5600 series of automatic calibers, the Lord Matic was designed for the discerning professional, offering high-quality finishing, a slim profile, and reliable functionality. During this decade, Seiko experimented boldly with case geometry, faceted crystals, and vibrant dials, resulting in some of the most dynamic and memorable designs of the era. The caliber 5606A remains highly respected among collectors for its refined architecture and reliable performance.
