The watch presents exceptionally well with sharp factory lines and a flawless dial presentation. Timegrapher testing shows -38s to -43s/day, which indicates a healthy movement. Dial and Hands The dial is the absolute highlight of this timepiece, featuring a mesmerizing vertical brushed texture with a gradient effect that transitions from a silvery taupe in the center to a deep, rich brown at the edges. The applied gold-tone indices and matching baton hands provide a warm and luxurious contrast against the cool steel case. The dial features applied gold "SEIKO" and "LM" logos, along with a framed day-date window at the three o'clock position. The entire face is viewed through an original faceted crystal, also known as "Cut Glass," which plays with the light in a unique way, adding depth and character to the watch. Case and Crystal The stainless steel case is preserved in stunning condition, retaining its original sharp geometry and brushed finishes. The design follows Seiko's distinct 1970s aesthetic with strong lugs and clean facets. The faceted mineral crystal is a rare and desirable feature, remaining in excellent condition with distinct edges that create beautiful visual distortions of the dial elements. The crown is recessed slightly into the case at the 3 o'clock position, maintaining the sleek profile. Movement Powering the watch is the high-grade Seiko Caliber 5606A automatic movement. This 25-jewel movement was a staple of the Lord Matic line, known for its reliability and slim profile. The movement is clean and offers reliable vintage performance. Strap The watch comes fitted on its original Seiko LM stainless steel bracelet. The bracelet features a multi-link design that is both comfortable and stylish, finished with a signed "LM" folding clasp. It accommodates a wrist size of approximately 18cm. Condition This timepiece is in excellent near-mint vintage condition. The case edges are crisp, suggesting the watch has seen minimal use or very careful handling over the decades. The dial is pristine with no visible spotting or aging. The crystal is clear and sharp. The movement is running and functioning correctly. Dimensions The case measures 36mm in diameter, excluding the crown, which was a classic size for gentlemen's watches of this period and wears comfortably on a modern wrist due to the case shape. Remarks This specific reference with the faceted crystal and gradient dial is becoming increasingly difficult to find in such well-preserved condition. It is a striking example of why the Lord Matic line is so revered by enthusiasts today, offering King Seiko-level finishing and style. History Introduced in 1968, the Lord Matic (LM) line was positioned just below King Seiko and Grand Seiko in the hierarchy, offering high-quality automatic movements and superior case finishing to the mass market. It became one of Seiko's most successful lines in the 1970s, introducing a variety of daring dial designs and case shapes that have become iconic representations of the era's horology. This example from July 1973 is a perfect testament to that golden age of Japanese watchmaking. / Second Vintage SKU: SEI-SLJ-0151
