Brand: Seiko Model: Lord Matic Reference Number: 5606-7310 Serial Number: 3D7579 Movement: Caliber 5606A Automatic Dial: Green Gradient with Vertical Faceted Crystal Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1973 Condition: Near-mint vintage condition, rare to find in this condition Dial and Hands The dial is the absolute highlight of this timepiece, featuring a stunning emerald green gradient that darkens towards the edges, intersected by a central vertical band. This visual depth is amplified by the original faceted crystal, which utilizes three distinct panes to catch and refract light in a kaleidoscopic manner. The applied gold-tone hour markers and handset are pristine, offering excellent legibility and a touch of luxury against the vibrant green backdrop. A framed day-date window is positioned at 3 o'clock, featuring a bilingual English/Kanji wheel. The Seiko LM and Suwa Seikosha logos are crisp and intact. Case and Crystal The stainless steel case is preserved in outstanding condition, showcasing the sharp, geometric lines characteristic of Seiko's design philosophy from this period. The brushed and polished surfaces remain distinct with well-defined edges, suggesting the watch has seen very little wrist time over the decades. The original faceted crystal is free from major scratches or chips, preserving the unique prismatic effect that makes this reference so desirable. The reference and serial numbers on the caseback are clearly visible and deep. Movement Powering the watch is the robust and highly regarded Seiko Caliber 5606A automatic movement, a 23-jewel mechanism known for its durability. This high-grade movement features both hand-winding and hacking capabilities. Timegrapher testing shows the watch running between +28 and +32 seconds per day, which indicates a healthy movement offering reliable vintage performance. Strap The watch is fitted with a high-quality black leather strap featuring contrasting tan stitching. The strap is in excellent, unworn condition and complements the vintage aesthetic of the case and dial perfectly, making it ready to wear immediately. Condition This timepiece is in Near-mint vintage condition, presenting as a very fresh and well-preserved example. The dial is flawless with no spotting or staining. The case retains its factory sharpness with only the faintest handling marks visible upon extreme close-up inspection. It is exceedingly rare to find this faceted crystal model in such clean condition. Dimensions The case measures approximately 36 mm in diameter excluding the crown, with a lug width of 18 mm. The lug-to-lug length makes it wear comfortably on a variety of wrist sizes, offering a classic vintage presence that remains relevant today. Remarks The Seiko Lord Matic "Faceted Glass" series represents one of the most creative periods in Seiko's history. Combined with the rare green gradient dial, this specific configuration is highly sought after by enthusiasts. The way the faceted glass interacts with the sunburst finish creates a visual depth that photos can barely capture. It is a stunning conversation piece that bridges the gap between a dress watch and a statement accessory. History Introduced in the late 1960s, the Lord Matic (LM) line was positioned just below the King Seiko and Grand Seiko in the brand's hierarchy, offering high-beat movements and sophisticated case finishing to the upper-mid market. The Caliber 5606 became a legendary workhorse for Seiko, serving as the foundation for many high-grade chronometers of the era. This specific model from 1973 showcases the adventurous design language that defined Seiko's output during the groovy 1970s. /Second Vintage SKU: SEI-SLJ-0026
