Remarks This Seiko Lord Matic 5606-8100 is a fantastic example of the "Vanac" style influence that permeated Seiko's designs in the mid-1970s. The combination of the rich blue dial and the cut glass makes this a conversation piece that stands out on the wrist, offering a unique aesthetic that modern watches rarely replicate. History Introduced in 1968, the Lord Matic line was a significant step forward for Seiko, bridging the gap between the mass-market Seiko 5 and the high-end Grand Seiko. It utilized the completely new 5606 movement, which was thinner and more refined than its predecessors. By the mid-1970s, the Lord Matic line embraced more experimental designs, as seen in this example, reflecting the adventurous fashion of the decade. / Second Vintage SKU: SEIU7DIWG0000
