    About This Watch

    Offered in this auction by Second Vintage The Seiko Lord Matic represents a golden era of Japanese watchmaking, serving as a sophisticated bridge between the brand’s standard offerings and the elite Grand Seiko and King Seiko lines. During the 1970s, Seiko experimented brilliantly with color and geometry, resulting in some of the most striking timepieces of the decade. This particular example captures that distinctive vintage charm perfectly, boasting a mesmerizing gradient dial and a sharply faceted case that reflects light with remarkable character. It stands as a testament to Seiko’s mastery of design and mechanical reliability, offering collectors a highly wearable and visually arresting piece of horological history. Brand: Seiko Model: Lord Matic Reference Number: 5606-7320 Serial Number: 307413 Movement: Automatic caliber 5606A, 23 jewels Dial: Gradient emerald green sunburst dial with applied gold-tone indices, presenting exceptionally clean and well-preserved. Case Size: 36 mm (excluding the crown) Case Material: Stainless steel Production Year: 1973 Condition: Excellent vintage condition with a remarkably clean dial and sharp case lines. Dial and Hands The dial is a captivating visual focal point, featuring a rich emerald green gradient that deepens to a dark forest hue at the outer edges. A subtle sunburst finish radiates from the center, catching the light dynamically from every angle. The dial is furnished with prominent, faceted gold-tone baton indices that provide a striking contrast against the green backdrop. The applied gold-tone Seiko and LM logos are crisp and perfectly positioned, while the day-date aperture at three o'clock is framed in a matching gold-tone window. The dial text reads Japan 5606 -7660T along the bottom edge. Visual inspection reveals the dial to be in exceptionally clean condition, free of noticeable moisture damage, spotting, or print loss. The faceted gold-tone baton hands feature a sleek central profile and remain in excellent shape, complementing the overall sharp and pristine presentation of the watch face. Case and Crystal The 36 millimeter stainless steel case exhibits a distinct tonneau-inspired geometry characteristic of the era. The case architecture is defined by its sharp, factory-like transitions between the heavily vertically brushed upper surfaces and the highly polished case flanks. These crisp lines indicate careful preservation, maintaining the original design intent without heavy softening. The flat crystal sits slightly raised with a beveled edge, providing a clear and unobstructed view of the vibrant dial beneath, showing only faint micro-wear at the extreme edges consistent with careful handling. The knurled crown is nestled closely to the case side, maintaining the sleek silhouette. The screw-down caseback is fully legible, displaying the Seiko branding, water resistance designation, and the 307413 serial number alongside the 5606-7320 reference code. Movement Powering this timepiece is the Seiko caliber 5606A, a highly regarded automatic movement from the brand's legendary 56-series family. The visible movement components, including the robust rotor stamped with Seiko and 23 Jewels, present cleanly with light age-related patina expected of a vintage mechanism. This caliber is celebrated for its sophisticated design and reliable performance. Running in vintage operational condition. Maintains the authentic mechanical character of the era, recording +60 to +65 seconds per day on the timegrapher. Strap The watch is fitted with its original multi-link stainless steel bracelet, an integral part of its 1970s aesthetic. The authenticity is confirmed by the prominent Seiko LM branding deeply stamped into the folding clasp, as well as the XBA and 020 codes clearly visible on the endlinks. The bracelet features a handsome combination of brushed outer links and polished center accents, echoing the finishing of the watch case. It accommodates a wrist size of up to 17.5 centimeters. Condition This Lord Matic is presented in excellent vintage condition. The case retains its sharp architectural lines and distinct brushing, showing only honest, superficial handling marks and light scratches that are entirely consistent with normal, careful wear over the decades. The dial is a standout feature, remaining remarkably clean and vibrant without the degradation often seen in colored dials of this period. The original bracelet shows moderate stretch typical of its age but remains secure and visually cohesive with the case. Overall, it is a highly attractive and well-preserved collector's piece. Dimensions The stainless steel case measures 36 millimeters in diameter, excluding the crown. The included original stainless steel bracelet is sized to fit a wrist of up to 17.5 centimeters. Remarks Colored-dial variants of the Lord Matic series have become increasingly sought after by vintage enthusiasts for their unique character and undeniable wrist presence. The combination of the emerald green gradient dial with the faceted gold-tone furniture creates a luxurious aesthetic that punches far above its weight class. Complete with its original signed bracelet, this example offers a cohesive and highly authentic vintage Seiko experience. History Introduced in the late 1960s, the Seiko Lord Matic was positioned just below the prestigious King Seiko and Grand Seiko lines, sharing much of the same advanced movement architecture. The 56-series calibers were instrumental in Seiko's pursuit of thinner, more sophisticated automatic watches. The Lord Matic line became a canvas for Seiko's most expressive designs in the 1970s, incorporating bold case shapes, faceted crystals, and vibrant dials. Today, the LM series is celebrated by collectors for delivering tremendous horological value, exceptional build quality, and quintessential Japanese design language from one of the industry's most creative eras. / Second Vintage SKU: SEI-LXX-0040
