The dial surface appears well-preserved, maintaining its vibrant color and texture. Case and Crystal The stainless steel case features the sharp, angular lugs characteristic of the Lord Matic series, though some edges have softened slightly with age. The case shows surface wear and scratches consistent with a vintage piece of this era. The watch is fitted with a faceted cut-glass crystal, a signature 1970s design element. The crystal exhibits noticeable scratches and wear across the facets, which is typical for original faceted crystals of this age, yet the unique light-refracting effect remains intact.

The movement is currently functioning, with timegrapher readings showing a daily rate of approximately -62 to -74 seconds, indicating a vintage movement that is running and operational. Strap The watch has been paired with a new black leather strap featuring an alligator grain pattern. The strap is in unworn condition and complements the dark tones of the dial, secured by a silver-tone pin buckle. Condition This timepiece is in good vintage condition. While the faceted crystal shows distinct signs of daily wear and scratching, the dial underneath remains in attractive condition. The case retains its distinct geometry with honest signs of use. The watch is running and presents as an authentic example of 1970s style. Dimensions The case measures 36 mm in diameter excluding the crown, a classic size that offers a comfortable and proportionate fit on a variety of wrist sizes. Remarks This Seiko Lord Matic is a charming example of the adventurous design language of the 1970s. The combination of the faceted crystal and the deep blue dial creates a dynamic visual experience on the wrist. History Introduced in 1968, the Lord Matic (LM) line was designed to bring high-quality automatic movements and sophisticated case designs to the mid-tier market. It played a crucial role in Seiko's history, bridging the gap between the robust Seiko 5 sports models and the high-precision King Seiko and Grand Seiko lines. The 5606 movement used in this series is widely respected for its slim profile and reliability, helping to establish Seiko's dominance in the mechanical watch market during the 1970s. / Second Vintage SKU: SEI-SLJ-0030
