【Description】 Presenting the Seiko Goldfeather, an iconic ultra-thin wristwatch from the 1960s, proudly made in Japan. Developed with the goal of creating a watch "as light as a feather," this model represents Seiko’s innovative spirit and technological achievement during the golden age of watchmaking. Traditional center-second movements are structurally difficult to make thin, as the gear wheels are layered concentrically. To overcome this, Seiko engineered a completely new movement with offset gears, allowing for an ultra-slim movement measuring only 2.95mm thick. Including the case and crystal, the total thickness is a mere 7.4mm, providing a superbly lightweight and comfortable fit under a shirt cuff. This hand-wound movement features 25 jewels for smooth and precise operation. The case is gold-filled (14K), offering greater durability and a richer appearance than simple gold plating. The snap-back case back further enhances its sleek form. The dial features a sunburst silver finish, with faint record-style grooves along the outer edge. Sculpted bar indices and elegant dauphine hands complement the sophisticated mid-century design. The dial printing is delicate and well-preserved. The strap is a brand-new Japanese-made leather band with a deployant clasp, ensuring both comfort and ease of use. This is a highly recommended piece for those seeking a refined, thin-profile vintage dress watch. 【Specifications】 Model: J15002E Movement: Manual winding Jewels: 25 Case: 14K Gold-Filled (Snap-back) Strap: New aftermarket leather strap (blue, deployant clasp) 【Size】 Case Diameter: approx. 36mm (excluding crown) Thickness: approx. 7.4mm Wrist Size: Up to approx. 19cm 【Condition】 Tested on a flat surface for 12 hours and confirmed to be running accurately without major delay.

As a vintage item over 60 years old, please refer to the images for further details and condition. 【Notes】 This watch is not water-resistant. Please avoid wearing it in the rain or on hot, humid days. To wind the mainspring, turn the crown slowly and gently in the upward direction. Over-winding may damage the spring. To pull out the crown, insert your fingernail between the case and the crown and gently lever it outward. The second hand does not stop when setting the time. Always remove the watch from your wrist before making adjustments, and operate it with care. ◆Important Notice◆ Buyers outside Japan are responsible for import duties, taxes, and additional charges.
