Seiko Lord Matic 覚光 (Kakkō) 5606-7050 (1970)

Available now on auction by Second Vintage This exceptional timepiece represents the golden era of Japanese watchmaking, combining the "Grammar of Design" aesthetic with robust mechanical engineering. The Seiko Lord Matic was positioned as a high-grade automatic watch in the company's lineup, sitting just below the King Seiko and Grand Seiko, often sharing similar movement architecture. This specific example features the desirable "one-piece" monocoque case design, accessed through the glass, which was an advanced waterproofing solution for its time. With its crisp silver sunburst dial and sharp case lines, this watch is a perfect entry point into serious vintage Seiko collecting. Brand: Seiko Model: Lord Matic Reference Number: 5606-7050 Serial Number: 072860 Movement: Automatic Caliber 5606 Dial: Silver sunburst with applied indices Case Size: 35 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1970 Condition: Stunning vintage condition. Timegrapher results show approximately -21s to -30s per day, which indicates a healthy movement running within acceptable vintage tolerances. Note: The crystal have a small crack in the bottom around 6:00-5:00 Dial and Hands The dial is a striking silver sunburst display that plays beautifully with the light, preserved in excellent condition. It features polished applied baton indices with black central inlays that match the hands, ensuring high legibility and a sophisticated monochrome look. The applied "Seiko" and "LM" logos are crisp and raised, adding depth to the face. A framed day-date window is positioned at 3 o'clock, featuring a blue Saturday text, which adds a subtle pop of color to the elegant composition. Please note, the framing around the day-date has some wear. The lume plots have aged to a warm, consistent creamy tone. Case and Crystal The stainless steel case is a highlight of this reference, utilizing a monocoque or "front-loading" construction where the movement is accessed through the crystal rather than a removable caseback. This design allows for a slimmer profile and historically improved water resistance. The case retains its sharp edges and brushed surfaces, showing only minimal handling marks consistent with a well-preserved vintage piece. Movement Inside beats the reliable Seiko Caliber 5606 automatic movement, a 23-jewel workhorse known for its durability and precision. This caliber features both hand-winding and hacking capabilities (the seconds hand stops when the crown is pulled), which were premium features for the era. The movement is running and functioning correctly, offering reliable vintage performance. Strap The watch is fitted with a high-quality black leather strap featuring contrasting white stitching. The strap complements the black accents on the dial markers and hands, enhancing the sporty yet dressy character of the watch. It is in new condition and ready for immediate wear. Condition This timepiece is in stunning vintage condition. The dial is exceptionally clean, free from spotting or patina damage often found on watches of this age. The case retains its original geometry with defined facets, avoiding the over-polished look common in the market. While there are minor surface signs of age, the watch presents as a collector-grade example. Dimensions With a case diameter of 35mm, the watch sits comfortably on a variety of wrist sizes, offering a classic vintage proportion that slides easily under a dress cuff. The lug-to-lug length and the cushion-style case shape give it a slightly larger presence than the dimensions suggest. Remarks This Lord Matic 5606-7050 is a testament to Seiko's manufacturing prowess in 1970. The combination of the monocoque case, the high-beat era design language, and the pristine dial makes it a standout piece. The distinct "Waterproof" marking on the back dates this piece strictly to the early 1970s before the terminology changed to "Water Resistant," adding a layer of collectibility for enthusiasts. History Introduced in the late 1960s, the Lord Matic (LM) series was essential in solidifying Seiko's dominance in the automatic watch market. It was designed to offer near-luxury finishing and advanced movements to the upwardly mobile professional class of Japan. The 5606 movement used in this line became legendary for its thin profile and reliability, serving as the base for many higher-end chronometers. Today, the Lord Matic is celebrated for offering Grand Seiko-adjacent styling and quality at an accessible value. / Second Vintage SKU: SEI-SLL-0018
