Brand: Seiko Model: Lord Matic Reference Number: 5606-7320 Serial Number: 3D1880 Movement: Automatic Caliber 5606A Dial: Deep blue with applied faceted markers, exceptionally clean and vibrant condition Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1973 Condition: Good vintage condition with a remarkably preserved dial and honest case wear Dial and Hands The dial of this Lord Matic is a masterclass in vintage Seiko finishing, featuring a rich, deep blue surface that remains exceptionally vibrant and clean. Careful inspection reveals a beautifully preserved dial free from moisture damage, spotting, or discoloration, which is a rarity for colored dials from this period. The dial furniture includes highly polished, applied silver-tone faceted hour indices that catch the light brilliantly, complementing the applied Seiko and Lord Matic logos. A sharply framed day-date aperture sits perfectly at the three o'clock position. The crisp white typography for the "AUTOMATIC" and "23 JEWELS" text, along with the Suwa Seikosha factory symbol, remains fully intact with no print loss. The silver-tone baton hands feature distinctive black central stripes, matching the sweep seconds hand, all of which present in outstanding visual condition with no signs of oxidation or degradation. Case and Crystal The 36mm stainless steel case features a robust, tonneau-influenced profile with sharply defined, hooded lugs that integrate seamlessly into the overall geometry. The case retains its factory transitions, showcasing brushed upper surfaces that contrast handsomely against the polished case flanks. The watch exhibits honest, age-consistent wear, with superficial handling marks and light scratches visible upon close inspection, but no deep gouges or signs of heavy over-polishing. The architectural integrity of the case lines remains strong. Crowning the case is the highly distinctive faceted crystal, a signature element of 1970s Seiko design. The geometric cuts of the glass create a stunning visual effect over the blue dial. The crystal shows some light surface scratches and minor flea bites along the faceted edges, which is entirely expected and consistent with original glass from this era. Movement Powering this timepiece is the Seiko Caliber 5606A automatic movement, a highly regarded engine from the Suwa factory known for its smooth sweep and day-date complication. Visual inspection of the movement reveals a clean overall appearance with bright base plates. Interestingly, the winding rotor is clearly stamped with "25 JEWELS" and "JAPAN 5606A", presenting a fascinating visual detail alongside the dial's 23-jewel designation. The caseback markings, including the 3D1880 serial number and 5606-7320 reference, remain crisp and legible. Running in vintage operational condition.

The aesthetic of the strap pairs beautifully with the dark blue dial and sharp steel case, elevating the overall presentation of the timepiece.

History Introduced in the late 1960s, the Lord Matic line was positioned just below the prestigious King Seiko and Grand Seiko collections, serving as the premium offering for the everyday professional.

The 1970s saw the Lord Matic line embrace the bold design trends of the decade, resulting in the creation of these striking faceted crystal models that remain highly sought after by collectors today.
