A day-date window is positioned at the 3 o'clock mark, framed in gold-tone metal. The silver stick hands are sleek and legible, completing the sophisticated 1970s aesthetic. Case and Crystal The stainless steel case measures 37mm and features the sharp, angular case lines characteristic of Seiko's "Grammar of Design" philosophy. The case shows signs of vintage wear with surface scratches and handling marks consistent with its age. The watch is fitted with its original-style faceted "Cut Glass" crystal, which features distinct angled planes. The crystal shows visible scratches and wear on the facets, which is common for these specific models, yet it retains its unique prismatic visual effect. Movement Powering the watch is the reliable Seiko Caliber 5606, a 23-jewel automatic movement that was a staple of the Lord Matic line. The movement features a signed rotor. Timegrapher testing indicates a performance of +31 to +38 seconds per day, which indicates a healthy movement running within acceptable vintage tolerances. Strap The watch is mounted on a stainless steel five-link bracelet that perfectly complements the case design. It features a signed "LM" folding clasp. The bracelet fits a wrist size of approximately 17.5 cm and shows normal stretch and surface wear consistent with the watch head. Condition This timepiece is in good vintage condition. While it shows honest signs of use throughout the case, bracelet, and crystal, the dial remains in attractive condition. The wear present is authentic to a watch from 1974 and adds to its vintage charm. Dimensions The case width is 37 mm excluding the crown, offering a classic vintage presence on the wrist. The integrated style of the lugs and bracelet gives it a substantial feel, while the faceted crystal adds vertical presence. Remarks This Seiko Lord Matic 5606-7310 is a fantastic example of the "Vanac-style" influence that permeated Seiko's designs in the mid-70s. The combination of the deep blue dial and the geometric crystal makes for a visually entertaining wearing experience. History The Seiko Lord Matic (LM) line was introduced in 1968 and served as the company's mid-range offering, sitting comfortably above the standard automatic models and just below the Grand Seiko and King Seiko lines. It was the first Seiko line to widely utilize the high-grade 5606 movement, which offered hacking and hand-winding capabilities. The LM series is celebrated today for its immense variety of dial designs and case shapes, representing a golden era of creativity in Japanese horology. / Second Vintage SKU: SEI-SLX-0006
