Brand: Seiko Model: Lord Matic Reference Number: 5606-7320 Serial Number: 307703 Movement: Automatic Caliber 5606A Dial: Emerald Green Gradient Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1973 Condition: Stunning vintage condition. The watch presents exceptionally well with a pristine dial and sharp case lines. Timegrapher results are included below. Dial and Hands The dial is the absolute highlight of this timepiece, featuring a stunning emerald green sunburst finish that graduates to a darker tone at the edges. The gold-tone applied baton indices and matching gold-tone handset provide a striking contrast against the rich green background. The applied gold "SEIKO" and "LM" logos are crisp and elevated, adding depth to the face. A framed day and date window is positioned at 3 o'clock, with a clean white wheel that ensures high legibility. The dial surface appears flawless, free from staining or oxidation. Case and Crystal The stainless steel case features the sharp, geometric "Grammar of Design" lines that Seiko made famous in the 1970s. The brushed surfaces on the top of the lugs transition seamlessly into polished sides. The defining feature of this reference is the original faceted crystal, often referred to as "cut glass," which remains in excellent condition and refracts light beautifully across the dial. The caseback is a screw-down type, clearly displaying the reference number 5606-7320 and the serial number, with the engravings remaining sharp and legible. Movement Powering the watch is the robust Seiko Caliber 5606A, a 23-jewel automatic movement that was a staple of high-grade Seikos from this era. The movement is clean and presents well visually. On the timegrapher, the watch is currently running with a deviation of approximately -55 to -60 seconds per day, which indicates a healthy movement offering vintage performance. Strap The watch comes fitted with its original stainless steel multi-link bracelet, which is a significant value factor for collectors. The bracelet features the correct signed "LM" clasp and articulates smoothly. It is currently sized to fit a wrist of approximately 19cm, making it wearable for most wrist sizes. Condition This Lord Matic is in stunning vintage condition. The case edges remain distinct, suggesting the watch has been treated with great care over the last five decades. The emerald dial is remarkably preserved, retaining its original vibrancy without the fading often seen in colored dials of this age. The gold plating on the hands and markers shows no signs of corrosion. The faceted crystal is clear, allowing the unique dial texture to shine through. Dimensions The case measures 36 mm in diameter excluding the crown, a classic size that offers a refined presence on the wrist. The faceted crystal adds a slight height profile that enhances the vintage character of the watch without making it cumbersome. Remarks Finding a Lord Matic with a green faceted dial in this condition is becoming increasingly difficult. The 5606-7320 reference is highly sought after because it bridges the gap between the standard Lord Matic line and the more eccentric Vanac series. This specific piece, manufactured in October 1973, is a perfect time capsule of 70s funk and luxury. It is a sales-appealing collector's piece that looks as good today as it did fifty years ago. History The Seiko Lord Matic (LM) line was introduced in 1968 and served as the mid-tier luxury offering from Suwa Seikosha, positioned just below King Seiko and Grand Seiko. The LM series was pivotal in bringing high-quality automatic movements and sophisticated case designs to a wider audience. The 5606 movement inside this watch was renowned for its thin profile and reliability, serving as the base for many higher-end chronometer-grade movements. The Lord Matic series is celebrated today for offering Grand Seiko-level case finishing and dial complexity at an accessible value point. / Second Vintage SKU: SEI-SLJ-0145
