With its warm gold-plated case, pristine sunburst dial, and reliable Seikosha movement, this timepiece offers collectors a highly wearable and historically significant piece of Seiko's prestigious automatic lineage. Brand: Seiko Model: Seikomatic Reference Number: J14075D Serial Number: 0013411 Movement: Automatic, Caliber 603, 20 Jewels Dial: Silver sunburst with applied gold-tone indices, exceptionally clean condition Case Size: 36 mm (excluding the crown) Case Material: Gold-Plated (EGP 20 Microns) with Stainless Steel Caseback Production Date: October 1960 Condition: Good vintage condition with a beautifully preserved dial Dial and Hands The dial of this Seikomatic is a visual delight, featuring a refined silver sunburst texture that plays beautifully with the light. It is adorned with applied, faceted gold-tone hour markers that provide excellent depth and contrast. Below the twelve o'clock position sits the applied gyro logo above the elegant, flowing "Seikomatic" script, while the lower half features crisp, sans-serif printed text denoting "DIASHOCK 20 JEWELS." The time is indicated by a set of sharp, gold-tone dauphine hands that remain in excellent condition. Upon close inspection, the dial exhibits stunning vintage preservation, remaining exceptionally clean and free of moisture marks, spotting, or prominent discoloration, presenting an incredibly attractive and crisp aesthetic. Case and Crystal The 36 millimeter case is executed in EGP 20 Microns gold plating, offering a warm and luxurious presence on the wrist. The case architecture features a slim bezel, gently sweeping lugs, and the signature recessed crown positioned neatly at four o'clock. A domed crystal protects the dial, offering clear visibility with only minor surface wear consistent with careful use. The case itself shows honest vintage character, with surface scratches and visible plating wear along the lug extremities and sharper edges, which is entirely typical for gold-plated watches of this era. The stainless steel snap-on caseback remains in good order, with the Seikomatic script, crane logo, and reference engravings clearly legible on both the exterior and interior surfaces. Movement Powering this classic timepiece is the visually clean Seikosha Caliber 603 automatic movement, featuring 20 jewels. The movement displays the beautifully engraved "SEIKOSHA SEIKOMATIC 20 JEWELS" rotor and the stamped caliber number on the base plate. Performing well within expected vintage tolerances; running strong and steady. The timegrapher results show a deviation of -30 to -36 seconds per day. Strap The watch is fitted with a period-correct black leather strap featuring an embossed texture and striking yellow contrast stitching that complements the gold tones of the case and dial. It is secured with a classic gold-tone pin buckle. Condition This Seikomatic is presented in good vintage condition. While the gold-plated case exhibits expected signs of wear, including localized plating loss and minor handling marks, the structural integrity remains sound. The true highlight is the dial, which has survived in near-mint cosmetic condition, entirely elevating the presence of the watch. Dimensions The case measures 36 mm in diameter, excluding the recessed crown, providing a classic and highly versatile mid-century dress watch profile that sits comfortably on the wrist. Remarks Combining a flawlessly aged dial with a character-rich gold-plated case, this Seikomatic is a superb example of early 1960s design. It is a sophisticated dress watch that captures the essence of Seiko's mid-century aesthetic, making it a compelling addition to any vintage collection. History Introduced in the early 1960s, the Seikomatic line was a cornerstone of Seiko's push into producing high-quality, reliable automatic timepieces for the domestic market. Utilizing the brand's highly efficient "Magic Lever" winding system, these watches were so effective at generating power from the wearer's wrist that Seiko purposely hid the crown at the four o'clock position to emphasize that manual winding was no longer necessary. The Seikomatic family laid the groundwork for many of Seiko's premium automatic lines, including the eventual development of the Grand Seiko and King Seiko automatic models.
