Seiko - Seikomatic 榮環 – Eikan – Circle of Honor - No reserve price - 15015 - Men - 1961

Presented for auction by Second Vintage This is a remarkable example of early 1960s Japanese watchmaking, representing the sophisticated design language that defined Seiko's ascent in the mechanical watch world. The Seikomatic was designed as a premium self-winding line, featuring a distinctive recessed crown at the 4 o'clock position to emphasize its automatic nature—implying that manual winding was unnecessary for daily wear. This specific reference boasts a beautifully preserved silver sunburst dial and the highly regarded Seikosha automatic movement, making it a sleek and historically significant choice for the vintage collector. Brand: Seiko Model: Seikomatic Reference Number: 15015 Serial Number: 1470364 Movement: Seikosha Automatic Caliber 603 Dial: Silver sunburst with applied indices Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1961 Condition: Excellent vintage condition with a very well-preserved dial and sharp case lines. Dial and Hands The dial features a stunning silver sunburst finish that radiates beautifully under light. It is adorned with polished, multifaceted applied baton indices that catch the light efficiently. The elegant "Seikomatic" script at 12 o'clock and the "Diashock 20 Jewels" text at 6 o'clock are crisp and legible. The sharp dauphine hands are polished to a high shine, complementing the minimalist aesthetic. The overall presentation of the dial is exceptionally clean for a watch of this era. Case and Crystal The stainless steel case measures a classic 36mm and is distinguished by its hidden crown located flush with the case at the 4 o'clock position, a signature design element of the early Seikomatic models. The lugs are angular and retain good definition. The caseback features the correct reference and serial number engravings, along with the manufacturing codes. The acrylic crystal is clear, allowing for an unobstructed view of the dial. Movement Powering the watch is the robust 20-jewel Seikosha automatic movement. The rotor is signed "Seikomatic" and "Seikosha," showcasing the golden era of Seiko manufacturing. The movement appears visually clean and is running within vintage tolerances, offering reliable vintage performance. Strap The watch is fitted with a black leather strap featuring white contrast stitching, which complements the silver tones of the dial and case, giving the watch a sporty yet dressy appearance suitable for modern wear. Condition This timepiece is in excellent vintage condition. The dial is virtually free of the spotting or heavy patina often found on pieces from the early 1960s. The stainless steel case shows light surface scratches consistent with careful use and age, but there are no deep dings or significant impact marks. The hidden crown operates correctly. Dimensions The case diameter is 36mm, offering a perfectly balanced presence on the wrist that slides easily under a dress cuff. Remarks This Seikomatic Reference 15015 is a testament to the "Grammar of Design" era that was beginning to take shape in Japan during the early 1960s. The combination of the clean dial, the hidden crown, and the automatic movement makes it a pure expression of mid-century horology. History Introduced in the early 1960s, the Seikomatic line was Seiko's first serious push into the automatic watch market intended for the mass premium sector. It served as a precursor to the automatic Grand Seiko and King Seiko models that would follow. The hidden crown design was a deliberate marketing feature, signaling to the owner that the efficiency of the "Magic Lever" winding system meant the crown would rarely need to be touched. This model stands as a significant milestone in Seiko's history of innovation. / Second Vintage SKU: SEI-SMJ-0007
