Brand: Seiko Model: Lord Matic Reference Number: 5606-8051 Serial Number: 514540 Movement: Automatic Caliber 5606 Dial: Teal sunburst with faceted crystal Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1975 Condition: Stunning vintage condition. The watch presents exceptionally well with a sharp case and flawless dial. Timegrapher testing indicates a daily rate of approximately -7 to -15 seconds which indicates a healthy movement offering reliable vintage performance. Dial and Hands The dial is the centerpiece of this watch, featuring a deep teal green sunburst finish that shifts in tone depending on the lighting conditions. It is fitted with applied silver baton indices and a framed day-date window at the three o'clock position. The hands are polished silver, providing excellent contrast against the rich background. The dial is viewed through an original-style faceted crystal (cut glass), which features vertical bevels that create unique light reflections and distortions, adding significant depth and character to the watch face. The dial surface appears free of aging or spots, preserving its original vibrancy. Case and Crystal The stainless steel case measures 36mm and features the distinct "Grammar of Design" lines associated with premium Seiko models from this period. The case edges remain defined, showing that the watch has been cared for over the decades. The faceted mineral crystal is a standout feature, remaining in excellent condition with sharp edges to the glass cuts, allowing for the intended visual effect. The crown is original and sits flush against the case. Movement Powering the watch is the high-grade Seiko Caliber 5606 automatic movement. This 23-jewel movement was a staple of the Lord Matic line, known for its slim profile and robustness. The movement is clean and running smoothly. Timegrapher results show a daily deviation between -7 and -15 seconds, which is well within acceptable standards for a vintage mechanical timepiece of this age. Strap The watch has been paired with a new blue leather strap featuring matching blue stitching and a crocodile grain pattern. The color of the strap perfectly complements the teal tones of the dial, creating a cohesive and stylish look suitable for both casual and dress wear. It is secured by a silver-tone buckle. Condition This timepiece is in stunning vintage condition. The case shows only very minor handling marks consistent with a well-preserved watch of its age. The dial is pristine, retaining its factory finish without visible patina or damage. The faceted crystal is clear and free from heavy scratches. The overall presentation is crisp, attractive, and ready for immediate wear. Dimensions With a case diameter of 36mm, this Lord Matic offers a classic mid-size profile that sits comfortably on the wrist. The lug-to-lug length and slim profile provided by the 5606 movement ensure it slides easily under a shirt cuff while still commanding presence due to the unique crystal and dial color. Remarks The reference 5606-8051 is particularly sought after due to the combination of the colored sunburst dial and the faceted crystal. Finding examples where the crystal edges are still sharp and the dial has not suffered from moisture damage is becoming increasingly difficult. This is a fantastic opportunity to acquire a distinctive 1970s Seiko that combines mechanical quality with a bold, artistic design language. History Introduced in the late 1960s, the Seiko Lord Matic (LM) series was designed to be the mid-tier luxury offering, sitting between the mass-market models and the high-end King Seiko and Grand Seiko lines. The LM series played a crucial role in Seiko's dominance during the 1970s, introducing thinner automatic movements and daring case designs. The 5606 movement inside this watch was one of the most advanced of its time, featuring hacking and hand-winding capabilities, and it remains a testament to Seiko's engineering prowess during their peak mechanical era. / Second Vintage SKU: SEI-SLJ-0047
