Brand: Seiko Model: Lord Matic Reference Number: 5606-7360 Serial Number: 592725 Movement: Automatic Caliber 5606A Dial: Vibrant green dial with applied faceted indices, exceptionally clean and free of visible spotting or damage. Case Size: 35 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1975 Condition: Excellent vintage condition, offering outstanding preservation and a highly attractive wrist presence. Dial and Hands The dial of this Lord Matic is a remarkable visual achievement, presenting a deep, vibrant emerald green surface that catches the light beautifully beneath its crystal. The dial is pristine, showing deep color saturation without any visible fading, moisture marks, spotting, or edge degradation. It features applied, tall faceted block indices with white center channels that provide excellent legibility and contrast. The applied silver-tone "SEIKO" and "LM" logos are crisp and prominent, sitting above the neatly printed "AUTOMATIC", "25 JEWELS", and the classic Suwa factory symbol. A framed day and date aperture rests perfectly at the three o'clock position. The faceted silver-tone baton hands feature black inserts and remain entirely sharp, completing a dial configuration that is exceptionally well-preserved and visually arresting. Case and Crystal The 35 mm stainless steel tonneau case showcases a classic 1970s profile, featuring a handsome contrast between the subtle radial brushing on the upper surface and the high-polish finish on the case flanks. The lug profiles retain their shape beautifully, and the case exhibits only honest, moderate surface wear consisting of light hairline scratches consistent with careful vintage use, with no heavy impacts or structural damage. The recessed crown sits seamlessly against the right flank. Above the dial sits the true defining feature of this reference, a dramatically faceted crystal with intersecting diagonal cuts that cast a dynamic checkerboard reflection across the dial. The crystal is clear and functional, though close inspection reveals a visible surface scratch near the eleven and twelve o'clock position, along with minor edge wear typical of raised, angled crystals from this era. Movement Housed inside is the in-house Seiko automatic caliber 5606A, a 25-jewel movement highly regarded for its refined architecture and smooth sweeping seconds. Visual inspection of the caliber reveals a very clean aesthetic, with clear "25 JEWELS", "JAPAN 5606 A", and "SEIKO" engravings on the winding bridge and rotor. The rotor, balance wheel, and visible gear train components present beautifully without heavy oxidation or signs of moisture intrusion. Running and operational, offering reliable vintage performance, timegrapher results reflect current performance measuring +6s to +15s/day. Strap The watch is fitted with its original period correct stainless steel multi-link bracelet. The authenticity of the bracelet is confirmed by the clearly stamped "SEIKO LM" signature on the outer folding clasp. The brushed and polished folded links match the case finish perfectly. The bracelet displays normal, honest signs of use including light surface marks and standard vintage stretch, currently accommodating a wrist size of up to 17.5 cm. Condition This Lord Matic is presented in excellent vintage condition. It is a well-preserved survivor that balances an untouched, near-flawless dial with an honestly worn case and bracelet. The factory finishes on the case remain distinctly visible, and the movement appears clean and structurally sound. The minor surface marks on the faceted crystal and the case do not detract from the overwhelming charm and high visual impact of the timepiece. Dimensions The watch measures 35 mm in diameter excluding the crown, offering a classic vintage profile that wears with considerable presence due to the tonneau case shape, the integrated appearance of the bracelet, and the height of the faceted crystal. Remarks Finding a Lord Matic with a pristine green dial and its original signed bracelet is increasingly difficult for collectors of vintage Japanese horology. The reference 5606-7360 perfectly encapsulates an era where watchmakers embraced bold geometry and vivid color. This piece delivers significant aesthetic value and mechanical pedigree, making it a compelling addition to any curated vintage collection. History Introduced in 1968, the Seiko Lord Matic was positioned just beneath the King Seiko and Grand Seiko collections, functioning as a premium daily wearer for the Japanese domestic market. The LM line heavily utilized the robust and sophisticated 56-series calibers, which also served as the foundation for the high-beat movements found in King Seiko models. Throughout the 1970s, the Lord Matic range became Seiko's playground for expressive design, resulting in highly varied case shapes, colorful dials, and elaborate faceted crystals. This specific iteration stands as a testament to that adventurous design philosophy, reflecting the global trend toward colorful, optimistic aesthetics during the decade. / Second Vintage SKU: SEI-SAX-0015
