Brand: Seiko Model: Lord Matic Reference Number: 5606-8030 Serial Number: 400109 Movement: Automatic Caliber 5606A Dial: Silver sunburst with printed Roman numerals Case Size: 37 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1974 Condition: Good vintage condition. The watch shows honest signs of wear consistent with its age, particularly on the case and bezel, while the dial remains well-preserved. Timegrapher results indicate the movement is functioning and working. Dial and Hands The dial features a refined silver sunburst finish that plays beautifully with the light. Unlike many Lord Matic models that feature stick indices, this example sports crisp, black printed Roman numerals, lending the watch a more formal and classical appearance. The dial is signed with the applied "Seiko" logo and the distinct "LM" emblem above the 6 o'clock position. A framed day-date window is positioned at 3 o'clock. The slender black hands provide excellent legibility against the light background. The dial surface appears clean with minimal aging, preserving the watch's elegant character. Case and Crystal The stainless steel case features the characteristic flowing lines of the Lord Matic series, measuring 37 mm in diameter. The case architecture includes tapered lugs and a polished bezel. There are visible signs of use throughout the case, including surface scratches and small dings on the bezel and case sides, which is typical for a watch of this vintage that has been enjoyed. The crystal exhibits some scratches and wear marks but remains intact. The caseback is clearly engraved with the reference 5606-8030 and "Water Resist - G" markings, along with the serial number. Movement Powering this timepiece is the reliable Seiko Caliber 5606A, a 25-jewel automatic movement known for its durability and capability. The movement features a signed rotor and appears intact. Current testing on a timegrapher shows a deviation of approximately -54 to -58 seconds per day, which indicates the movement is running. Despite the variance, the movement is running within vintage tolerances for an unserviced piece. Strap The watch has been fitted with a green leather strap featuring contrasting white stitching. The strap texture complements the vintage aesthetic of the case, adding a touch of color that pairs well with the silver dial. It is in good condition and ready for wear. Condition This timepiece is in good vintage condition. While the stainless steel case shows evident wear, scratches, and handling marks indicative of its 50-year history, the overall structure remains sharp. The dial is the highlight, remaining attractive and legible. The mechanical components are functioning, offering an authentic vintage ownership experience. Dimensions The case measures 37 mm in diameter excluding the crown, offering a classic mid-size profile that sits comfortably on a variety of wrist sizes. The lug design ensures a balanced presence on the wrist. Remarks The Lord Matic series was a significant line for Seiko in the 1970s, offering high-grade movements in stylish cases. This specific reference stands out due to the Roman numeral dial configuration, which is less common than the standard baton marker variants. It is a charming example of the "Grammar of Design" era influence mixed with traditional dress watch elements. History Introduced in 1968, the Lord Matic (LM) line was positioned as a high-mid-range offering, superior to the standard automatic lines and utilizing the 56-series movement base that was also found in some King Seiko and Grand Seiko models of the time. Produced in October 1974 based on the serial number, this watch hails from a period when Seiko was dominating the global market with both mechanical and quartz innovations. The Lord Matic remains a favorite among collectors for offering exceptional build quality and design at an accessible point in the vintage market. / Second Vintage SKU: SEIX0XKZ00000
