Brand: Seiko Model: Lord Matic Reference Number: 5606-7310 Serial Number: 4N9113 Movement: Automatic caliber 5606A, 23 jewels Dial: Green gradient with applied gold-tone indices, pristine condition Case Size: 36 mm (excluding the crown) Case Material: Stainless steel Production Year: 1974 Condition: Excellent vintage condition with exceptionally preserved dial and original bracelet Dial and Hands The dial features a captivating green gradient finish that shifts dynamically under different lighting conditions, further enhanced by the optical geometry of the overlying crystal. It is adorned with applied gold-tone baton indices featuring a distinct fluted texture, perfectly matching the gold-tone baton hands which carry a black central stripe for optimal legibility. A framed day-date aperture sits prominently at the three o'clock position. Careful visual inspection reveals an exceptionally clean surface, free from spots, moisture stains, or discoloration. The factory typography, including the applied Seiko and LM logos alongside the Suwa factory symbol, remains sharp and fully intact, showcasing an outstanding level of preservation. Case and Crystal The 36 mm stainless steel case exemplifies the bold architectural design language of the era, featuring a tonneau-style silhouette with integrated hooded lugs. The case retains strong lines, exhibiting a sharp transition between the vertically brushed upper surfaces and the brightly polished flanks. Honest, age-consistent handling marks and light hairline scratches are visible, indicating normal wear without signs of heavy, shape-altering polishing. The watch is fitted with a highly distinctive faceted crystal that divides the dial into striking geometric quadrants. This crystal displays minor edge wear and superficial scratches visible under close inspection, which are entirely consistent with its vintage provenance and do not hinder the dramatic visual effect. Movement Powering this timepiece is the Seiko caliber 5606A automatic movement, marked with 23 jewels. Close-up images of the movement reveal a clean mechanical environment, with the rotor and bridges presenting well-preserved factory finishes. The caseback features crisp, legible engravings, clearly displaying the Seiko Water Resistant text, the reference number 5606-7310, and the serial number 4N9113, which confidently dates the production of this watch to November 1974. Strap The watch is secured by its original stainless steel brick-link bracelet, a rare and highly desirable inclusion that completes the factory aesthetic. The folding clasp is distinctly stamped with the period-correct Seiko LM branding. The bracelet exhibits normal signs of vintage wear, including light surface scratches and minor stretch, comfortably accommodating a wrist size of up to 17.5 cm. Condition Graded in excellent vintage condition. This Lord Matic has been wonderfully preserved, highlighted by a pristine dial that remains free of age-related degradation. The case maintains its original geometric integrity and factory finishes, showing only moderate, honest wear. The original faceted crystal and LM-signed bracelet complete a highly authentic and visually striking collector piece. Dimensions The stainless steel case measures 36 mm in diameter, excluding the crown. The included original bracelet will accommodate a wrist circumference of up to 17.5 cm. Remarks The Seiko Lord Matic 5606-7310 is a masterclass in 1970s watch design, perfectly balancing technical capability with flamboyant styling. The interplay between the rich emerald-toned dial and the factory faceted crystal creates an optical depth that is rarely seen in modern timepieces, making this a standout addition to any serious vintage portfolio. History Introduced in the late 1960s, the Lord Matic series was positioned directly below the Grand Seiko and King Seiko lines, sharing much of the same high-quality mechanical DNA and finishing standards. By the 1970s, Seiko began experimenting heavily with vibrant dial colors and intricately faceted crystals, capturing the energetic and colorful spirit of the decade. These expressive models have become highly sought after by contemporary collectors for their unique visual presence and robust, reliable movements.
