Brand: Seiko Model: Lord Matic Reference Number: 5606-7360 Serial Number: 4N5568 Movement: Automatic Caliber 5606A, 25 Jewels Dial: Gradient amber brown dial with applied faceted gold-tone indices, presenting in exceptionally clean condition Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1974 Condition: Good vintage condition with honest case wear, cosmetic rotor aging, and a remarkably preserved dial Dial and Hands The dial is a masterclass in 1970s finishing, featuring a rich gradient amber-brown tone that transitions from a vibrant copper center to darkened edges. The surface is exceptionally clean, showing no visible moisture marks, spotting, or UV damage, retaining its factory luster beautifully. The typography is crisp, with the Seiko and LM logos proudly applied in a gold tone, while the "AUTOMATIC" and "25 JEWELS" text is sharply printed in white above the Suwa factory symbol. The applied hour markers are highly dimensional, featuring faceted gold-tone borders with bright white central channels that perfectly match the polished baton hands. A framed day-date aperture sits cleanly at the three o'clock position, displaying a vibrant blue 'SAT' indicator against a white wheel. Case and Crystal The 36mm stainless steel case features a classic 1970s tonneau or cushion profile with integrated hooded lugs. The case exhibits honest vintage wear, with handling marks, light surface scratches, and minor scuffs visible on the polished case flanks and the brushed upper surfaces. The transitions between the brushed tops and polished sides remain distinctly defined, avoiding the overly rounded look of heavy polishing. The caseback is clearly engraved with the reference 5606-7360 and serial number 4N5568. The watch is fitted with a striking, highly elevated faceted crystal that acts as a prism, casting unique reflections and adding immense depth to the dial beneath. The crystal remains in highly presentable condition, allowing an unobstructed view of the vibrant dial. Movement Powering this timepiece is the Seiko Caliber 5606A, a 25-jewel automatic movement renowned for its smooth sweep and reliable architecture. Visual inspection of the movement reveals prominent surface oxidation and plating loss localized specifically on the winding rotor, presenting as a mottled green and grey texture. Despite this cosmetic aging on the rotor, the underlying plates, gears, and balance assembly appear visually orderly. Performing well within expected vintage tolerances; running strong and steady. The timegrapher records a deviation of -25-30s/day. Strap The watch is fitted with its period-correct original stainless steel bracelet, featuring folded links and a brushed finish. The folding clasp is prominently stamped with the Seiko and LM logos, and the endlinks bear the correct XBA 120 factory stampings. The bracelet exhibits normal vintage stretch and surface wear consistent with the case, accommodating a wrist size of up to 18.5 cm. Condition This timepiece is presented in good vintage condition. The dial and hands are stunningly preserved, standing out as the highlight of the watch. The case and bracelet show expected, honest signs of daily wear including light scratches and handling marks, while maintaining good overall structural integrity. The mechanical movement exhibits notable cosmetic surface oxidation on the rotor, though it remains fully operational. Dimensions Case Size: 36 mm Wrist Size: 18.5 cm Remarks With its combination of a faceted crystal and a gradient dial, this Lord Matic is a quintessential representation of Seiko's most expressive design era.

History Introduced in the late 1960s, the Seiko Lord Matic (LM) series was positioned just below the prestigious King Seiko and Grand Seiko lines, serving as the premium choice for the working professional. The 5600 series of movements utilized in the LM range were highly regarded for their thinness and reliability, eventually serving as the foundational architecture for many King Seiko models. Throughout the 1970s, the Lord Matic line became Seiko's playground for innovative case shapes, vibrant colored dials, and experimental faceted crystals, making them highly sought after by today's collectors of vintage Japanese horology.
