Brand: Seiko Model: Lord Matic Reference Number: 5605-7050 Serial Number: 140997 Movement: Automatic Caliber 5605, 25 Jewels Dial: Silver sunburst with applied faceted indices, showing light age-consistent spotting Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Date: April 1971 Condition: Good vintage condition with sharp case geometry Dial and Hands The silver sunburst dial is a masterclass in classic Seiko finishing, catching the light beautifully to create a dynamic visual display. It features applied faceted baton hour markers, each detailed with a central black stripe to enhance legibility and contrast. The applied "SEIKO" and "LM" logos are crisp and prominent, complemented by the printed "AUTOMATIC" text and the Suwa factory symbol above the six o'clock position. A framed date window sits neatly at three o'clock. The dauphine-style hour and minute hands mirror the indices with matching black central channels, accompanied by a slender sweep seconds hand. Careful visual inspection reveals a scattering of fine spotting and light surface aging across the dial, particularly visible under macro photography. This light speckling represents honest vintage aging, adding character without detracting from the overall handsome appearance and legibility of the watch face. Case and Crystal The 36mm stainless steel case utilizes a specialized front-loading monocoque construction, a design choice intended to improve water resistance and structural integrity, as indicated by the "OPEN THRU GLASS" engraving on the caseback. The case geometry is striking, featuring sharp, faceted lugs and distinct transitions between the polished flanks and brushed upper surfaces. The case remains well-defined, showing honest handling marks, light scratches, and standard signs of wear consistent with its vintage age, yet retaining its factory proportions. The unsigned knurled crown is well-proportioned for comfortable operation. The dial is protected by a flat Hardlex crystal, which remains in highly presentable condition, offering a clear and unobstructed view of the dial beneath. Movement Powering this timepiece is the Seiko Caliber 5605, an automatic movement featuring 25 jewels and a date complication. The 5600 series is highly regarded among collectors for its durability, slim profile, and smooth operation, serving as the foundational architecture for many of Seiko's most respected models of the era. Performing well within expected vintage tolerances; running strong and steady. The timegrapher indicates a deviation of +20 to +24 s/d.
