It features raised gold-tone block indices and matching gold-tone baton hands, creating a luxurious contrast against the deep blue background. The applied gold "SEIKO" and "LM" logos are crisp and intact. A framed day-date window is positioned at the three o'clock mark, adding practical functionality to the elegant display. The dial surface appears remarkably clean and free from significant aging or spotting. Case and Crystal The stainless steel case features the distinct angular geometry typical of early 1970s Seiko design, often referred to as the Grammar of Design style. The case retains its original sharp edges and definition, with a mix of brushed upper surfaces and polished sides. There are visible surface scratches and handling marks throughout the metalwork consistent with a vintage watch of this era. The crystal shows some signs of use, including marks along the edges, but remains clear enough to enjoy the vibrant dial beneath. Movement Powering the watch is the reliable Seiko Caliber 5606 automatic movement, a 25-jewel high-beat mechanism known for its durability and precision. The movement is clean and visible through the open caseback photos, showcasing the industrial finish of this workhorse caliber. Timegrapher testing indicates the watch is running between +18 and +22 seconds per day, which indicates a healthy movement offering reliable vintage performance. Strap The watch is fitted with a black textured strap featuring white contrast stitching, which complements the sporty yet elegant nature of the watch. The strap is in very good condition and is secured by a silver-tone buckle, making it ready for immediate wear. Condition This timepiece is in excellent vintage condition. The dial is exceptionally well-preserved, retaining its vibrant color and finish. The case is honest and unpolished, preserving the original factory lines while showing normal wear appropriate for a watch from 1973. The movement is functioning well and keeping time within acceptable vintage tolerances as noted by the timegrapher results. Dimensions The case measures 35 mm in diameter excluding the crown, a classic size that sits comfortably on a variety of wrist sizes. The lug-to-lug distance and slim profile allow it to slide easily under a shirt cuff while still having enough presence to be noticed. Remarks The Lord Matic series was positioned as a high-quality mid-tier offering in Seiko's lineup, sitting just below the King Seiko and Grand Seiko models. It brought high-end movement architecture and sophisticated case designs to a wider audience. This specific reference, with its electric blue dial and gold accents, is a desirable configuration that captures the funky yet refined spirit of 1970s design. History Introduced in the late 1960s, the Seiko Lord Matic (LM) line was essential in solidifying Seiko's dominance in the automatic watch market. The 5606 movement inside was one of the most widely used and respected calibers of the era, offering features like hacking and hand-winding that were advanced for the time. This specific example, produced in October 1973, stands as a testament to the enduring quality of Suwa Seikosha's manufacturing during one of the brand's most innovative periods. / Second Vintage SKU: SEI-SLX-0024
