The crystal is well-preserved and clear, allowing an unobstructed view of the vibrant dial. The screw-down caseback is in excellent condition, with all factory engravings, including the reference and serial numbers, remaining deep and highly legible.

History Introduced in the late 1960s, the Lord Matic line was positioned just below the top-tier luxury models of its era, sharing much of the same advanced movement architecture and attention to detail. By the early 1970s, the brand began experimenting heavily with vibrant dial colors, gradient finishes, and intricately faceted crystals, perfectly capturing the bold design ethos of the decade. The 5606 caliber became renowned for its thin profile and reliable performance, cementing the Lord Matic as a historically significant and highly collectible series among discerning horology enthusiasts. / Second Vintage SKU: SEI-LNX-0005
