Seiko Lord Matic 5606-7070 (1970)

Offered in this auction by Second Vintage This Seiko Lord Matic features a striking vibrant blue dial that immediately captures attention, making it a standout piece from the 1970s. As a reference 5606-7070, it embodies the robust engineering and sharp aesthetics that defined Seiko's golden era.

Brand: Seiko Model: Lord Matic Reference Number: 5606-7070 Serial Number: 062681 Movement: Automatic Caliber 5606 Dial: Matte Blue Case Size: 37 mm (excluding the crown) Case Material: Stainless Steel Production Year: June 1970 Condition: Good vintage condition. The watch presents an honest vintage aesthetic with a very well-preserved dial. Timegrapher results show the movement running between -52 and -55s/day. Dial and Hands The matte blue dial is the highlight of this timepiece, presenting a rich and even color that contrasts beautifully with the applied silver baton indices. The hands are polished silver stick style with central luminous inserts that show patina consistent with age. The applied "SEIKO" and "LM" logos are crisp and bright. A framed day-date window is positioned at 3 o'clock, featuring a desirable English and Kanji day wheel. Case and Crystal The stainless steel case features the unique "open thru glass" front-loading design, marked clearly on the caseback. The case shows signs of wear and handling consistent with its age, including surface scratches and softening of the edges, but retains its original geometry. The crystal exhibits some scratches and marks visible under direct light. The caseback engravings, including the "Water Proof" text, remain legible. Movement Powered by the Seiko Caliber 5606, this 23-jewel automatic movement was a high-grade workhorse of its era, featuring hand-winding and hacking capabilities. The movement is currently running, with timegrapher readings indicating a rate of approximately -52 to -55 seconds per day, suggesting it is functioning but running slow. Strap The watch is fitted with a black leather strap featuring an alligator grain pattern and matching stitching. It is secured by a silver-tone pin buckle that complements the case finish. Condition This timepiece is in good vintage condition. The visual appeal is strong, primarily due to the excellent condition of the blue dial which is free from major spotting or damage. The case shows honest wear expected from a watch produced in 1970. The mechanical performance is currently outside standard chronometer specs as noted in the timegrapher results. Dimensions The case measures 37 mm in diameter excluding the crown, offering a classic size that wears comfortably on a variety of wrist sizes. Remarks This specific reference 5606-7070 is notable for its "Water Proof" caseback marking, which helps date it precisely to the transition period before Seiko switched to "Water Resistant" in the early 1970s. The combination of the blue dial and the Kanji day wheel makes this a highly collectible variation of the Lord Matic series. History Introduced in 1968, the Lord Matic (LM) line was positioned as Seiko's mid-range offering, sitting just below the King Seiko and Grand Seiko lines. It utilized the sophisticated 56-series movement, which was thinner and more advanced than previous iterations, allowing for sleeker case designs. The Lord Matic series played a crucial role in establishing Seiko's reputation for producing high-quality, stylish, and durable automatic watches during the quartz revolution. / Second Vintage SKU: SEIACT7BZ0000
