It is adorned with applied baton hour markers featuring black center inserts for contrast. The silver hands are sharp and faceted to match the indices. A framed day-date window is positioned at 3 o'clock. The applied "SEIKO" and "LM" logos are crisp and raised, adding to the three-dimensional quality of the watch face. The dial remains in excellent preservation with no major spotting or damage visible. Case and Crystal The stainless steel case measures 36mm and features the sharp angular lines characteristic of 1970s Seiko design. The case geometry creates a unique presence on the wrist with integrated-style lugs. There are visible signs of use throughout, including surface scratches and small nicks on the bezel and case sides consistent with its age and honest vintage wear. The caseback is a screw-down type featuring the "Water Resist-G" engraving and clearly visible reference and serial numbers. The crystal is clear and presents well. Movement Powering this watch is the highly regarded Seiko Caliber 5606 automatic movement. This 23-jewel movement was a high-grade workhorse of the era. The movement has been serviced and is running within excellent parameters for a vintage piece, showing -2 to -3 seconds per day with strong amplitude on the timegrapher. The rotor and bridges appear clean and free of corrosion. Strap The watch has been fitted with a black vintage-style leather strap featuring white contrast stitching. The strap provides a comfortable fit and complements the monochromatic aesthetic of the silver dial and steel case. Condition This timepiece is in good vintage condition. While the case shows evident cosmetic wear in the form of scratches and dings from decades of use, the lines remain distinctive. The dial is the highlight, preserved in excellent condition. The movement has been professionally serviced and offers reliable vintage performance. Dimensions The case measures 36mm in width excluding the crown. The lug design allows it to wear comfortably on a variety of wrist sizes, maintaining a classic vintage profile. Remarks The Lord Matic 5606-8090 is a perfect entry point into vintage Seiko collecting or a sophisticated addition to an established collection. The combination of the serviced high-beat movement and the vertically brushed dial makes this a compelling value proposition. History Introduced in 1968, the Lord Matic line was essential in solidifying Seiko's reputation for automated mass-produced luxury. Utilizing the 56 series movement, which was a thinner and more advanced caliber than its predecessors, the LM series bridged the gap between the standard Seiko 5 range and the high-end King Seiko models. This 1975 example comes from the mature period of the LM production run, embodying the refined design language that makes these watches highly sought after today. /Second Vintage SKU: SEI-SLJ-0087
