Timegrapher results included below. Dial and Hands The silver dial is in exceptional condition, featuring a subtle sunburst finish that plays beautifully with the light. It is adorned with polished, multifaceted applied baton indices, with a double marker at the 12 o'clock position. The iconic "Seiko Lord Marvel" branding is rendered in a sharp, elegant script font. The polished dauphine hands are original and retain their sharp profile, complementing the indices perfectly. Case and Crystal The stainless steel case remains in excellent vintage condition, retaining sharp edges and clearly defined chamfers on the lugs, suggesting it has been treated with great care over the decades. The polished surfaces show only minor handling marks consistent with careful use. The caseback is screw-down and features crisp, deep engravings of the Seiko Lord Marvel script and reference numbers, which are often worn down on examples from this period. The crystal is clear and free of distracting scratches, offering an unobstructed view of the dial. Movement Powering this timepiece is the Seiko Caliber 5740A, a 23-jewel manual wind movement known for its durability and precision. The movement plates appear clean and bright in the photographs. Timegrapher testing indicates a daily deviation of approximately -49 to -51 seconds per day, which indicates a healthy movement functionality. Strap The watch is fitted with a vintage-style brown leather strap featuring an alligator grain pattern and contrasting stitching. The strap complements the warmth of the silver dial and is in good, wearable condition, ready for immediate use. Condition This timepiece is rated in Excellent vintage condition. The dial is nearly flawless, preserving its original luster without spotting or staining. The case geometry is strong, and the caseback engravings are remarkably legible. The movement is clean and functioning, making this a collector-grade example of a significant mid-century Seiko. Dimensions The case measures 35 mm in diameter excluding the crown, a classic size that offers a refined presence on the wrist suitable for formal or casual wear. Remarks The Lord Marvel 5740-1990 is a testament to Seiko's commitment to quality during the 1960s. As the first Japanese watch to feature a high-beat movement in later iterations, this earlier 5740A version laid the groundwork for that innovation. It offers the same high-quality case construction and dial finishing found in King Seiko and Grand Seiko models of the same era but at a more accessible entry point for collectors. History Introduced in the late 1950s, the Lord Marvel line was Seiko's top-tier luxury watch before the introduction of the Grand Seiko. It served as a platform for Seiko to demonstrate their manufacturing prowess and high-end finishing capabilities. The reference 5740-1990 was a staple of the 1960s, bridging the gap between standard production models and the ultra-luxury segment. This specific example, produced in January 1966, captures the essence of that golden era of Japanese watchmaking. Payment and Shipping Payment must be completed within 1-3 days after purchase.
