Seiko Lord Matic 光縁 (Kōen) 5606-7000 (1960-1969)

Presented for auction by Second Vintage This Seiko Lord Matic Reference 5606-7000 is a remarkable example of Japanese horological history, combining the elegant "Grammar of Design" aesthetics of the late 1960s with a historically significant provenance. As a higher-tier offering sitting just below King Seiko in the vintage hierarchy, the Lord Matic series offered exceptional finishing and advanced movements. This particular piece is especially desirable due to its caseback engravings, which indicate it was a presentation watch for the Japanese National Railways (JNR), adding a layer of industrial heritage to its horological appeal. Brand: Seiko Model: Lord Matic Reference Number: 5606-7000 Movement: Automatic Caliber 5606 Dial: Silver Sunburst Case Size: 36 mm (excluding the crown) Case Material: Gold Plated (SGP) with Stainless Steel Back Production Year: c. 1969 Condition: Good vintage condition Dial and Hands The watch features a sophisticated silver sunburst dial that remains in attractive condition. It is adorned with multi-faceted applied gold-tone hour markers featuring black central inserts, a style echoed in the sharp dauphine hands which creates excellent legibility and contrast. The gold applied "SEIKO" and "LM" logos add depth to the face, while the framed day-date window at the three o'clock position balances the layout. The text "Japan 5606-7001T" is visible at the bottom of the dial. Case and Crystal The case is constructed from Seiko Gold Plate (SGP) and features the distinct C-shape or cushion design characteristic of the era. The case reflects its vintage nature with visible surface scratches and signs of wear to the plating, particularly on the edges and lugs, consistent with honest use over decades. The screw-down caseback is made of stainless steel and bears the inscription "Waterproof," a key detail that dates this watch to the late 1960s or very early 1970s before the industry switch to "Water Resistant." Movement Powering this timepiece is the highly regarded Seiko Caliber 5606 automatic movement, a 23-jewel workhorse known for its reliability and its hacking and hand-winding capabilities. The movement is performing within acceptable vintage parameters, with a timegrapher reading of -17s to -23s/day, which indicates reliable movement function for a watch of this age. Strap The watch has been fitted with a new black leather strap featuring contrasting gold stitching. The strap complements the gold tones of the case and the black accents on the dial indices, giving the watch a sporty yet refined presence on the wrist. Condition This timepiece is in good vintage condition. While the case shows expected signs of age such as surface wear and patina to the gold plating, the dial remains clean and presents beautifully. The historical significance of the caseback engravings and the unpolished honesty of the case make this a compelling example for collectors who value character and history. Dimensions The case measures 36mm in diameter excluding the crown, a classic size that offers a comfortable and proportionate fit on a variety of wrist sizes. Remarks The most striking feature of this watch is the Japanese script engraved on the caseback. These inscriptions denote it as a commemorative award from the Japanese National Railways (JNR). Such pieces were typically awarded for long service or meritorious efficiency, making this not just a watch, but a tangible piece of Japan's post-war industrial era. History Introduced in 1968, the Lord Matic line was equipped with the sophisticated 5600 series movement, which was a thin, high-grade automatic caliber that served as the base for many Chronometer-grade Seikos. The Lord Matic was positioned as a premium gentleman's watch, bridging the gap between the mid-range offerings and the high-end Grand Seiko and King Seiko lines. Today, these watches are celebrated for their quality construction and timeless design language. /Second Vintage SKU: SEI-SLJ-0025
