Presented for auction by Second Vintage This is a remarkable example of the Seiko Goldfeather, a model that holds a special place in horological history as one of the slimmest center-second watches ever produced at its launch in 1960. Designed to compete with Swiss ultra-thin dress watches, the Goldfeather represents the pinnacle of mid-century Japanese elegance and technical prowess. Its slim profile and clean, sophisticated dial make it a perfect dress watch that wears larger than its dimensions suggest due to the thin bezel, offering a timeless aesthetic for the discerning collector. Brand: Seiko Model: Goldfeather Reference Number: J14060 Serial Number: 0910725 Movement: Manual Wind Seikosha 25 Jewels Dial: Silver Sunburst Case Size: 35 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1960 Condition: Excellent vintage condition Dial and Hands The silver sunburst dial is preserved in beautiful condition, radiating a classic mid-century aesthetic with a fine texture that catches the light elegantly. It features slender, applied silver baton indices that complement the minimalist design perfectly. The original thin hands are sharp and clean, enhancing the watch's understated elegance. The script "Seiko Goldfeather" text at the twelve o'clock position remains crisp and distinct, as does the "Diashock 25 Jewels" designation at six o'clock. Case and Crystal The stainless steel case is notable for its exceptionally slim profile, which was a technological marvel of its era. The case retains its original lines with defined lugs, showing only light surface wear and hairline scratches consistent with careful handling over the decades. The snap-on caseback features the iconic crane emblem and clear engravings, including the model and serial numbers, which are sharp and legible. The crystal is clear and free from distracting marks, offering an unobstructed view of the dial. Movement Powering this timepiece is the high-grade 25-jewel manual wind movement signed by Seikosha. This caliber was renowned for being the thinnest center-second movement produced by Seiko at the time. The movement presents very cleanly with gold-toned text and jewel settings. It is currently running within vintage tolerances, with timegrapher results showing a deviation of approximately -5 to -11 seconds per day and strong amplitude, indicating a healthy mechanism offering reliable vintage performance. Strap The watch is fitted with a high-quality burgundy leather strap featuring contrasting yellow stitching and a unique texture, which adds a warm and stylish character to the cool silver tones of the watch. The strap is in excellent condition and ready for immediate wear. Condition This piece is in excellent vintage condition. The dial is remarkably clean for its age, and the case shows honest but minimal wear without signs of heavy polishing or abuse. The movement is clean and functioning well, making this a collector-grade example of a significant Seiko model. Dimensions The case measures 35 mm in diameter excluding the crown. Due to the very thin bezel and large dial opening, the watch commands a significant presence on the wrist that feels modern and refined despite its vintage proportions. Remarks The Goldfeather is an essential reference for Seiko collectors, marking the era when the brand began seriously challenging Swiss dominance in ultra-thin watchmaking. Finding an example in stainless steel with such a well-preserved dial and the correct crane caseback is becoming increasingly difficult. This specific watch captures the essence of the "Grammar of Design" era before it was formally named, focusing on perfect proportions and legibility. History Introduced in 1960, the Seiko Goldfeather was marketed as the "thinnest center-second watch in the world" at the time of its debut. It succeeded the Cronos and Marvel lines, pushing the boundaries of movement architecture to achieve a flatter profile. This model paved the way for future ultra-thin successes and remains a testament to the rapid advancement of the Daini Seikosha factory during the golden age of Japanese watchmaking.
