Thank you for visiting my auction. I am pleased to offer this item for your collection. 1. Main Specifications Brand: Seiko Credor Model Name: Ultra-thin High Accuracy Quartz Model Number: 4J81-5020 Caliber: 4J81 (High Accuracy Quartz) Case Size: Approx. 21mm (excluding crown) [Model Description & Appeal] This is the Seiko Credor 4J81-5020, from Seiko's premium luxury line. The standout features of this model are its movement, the Cal. 4J81—renowned for high-precision accuracy—and its elegant square case design. The square form, which perfectly balances sharp lines with a soft aesthetic, lends an urban and intellectual impression to the wearer's wrist, fitting as beautifully as a piece of fine jewelry. The 21mm size offers excellent visibility while maintaining the beauty of its geometric lines, embodying a timeless elegance that transcends trends. It is a true masterpiece of Japanese luxury horology, living up to the name "Credor" (The Golden Peak). 2. Condition It is currently in working order, though the exact accuracy has not been tested. As this is a vintage item, there are minor scratches and dirt on the case and crystal from previous use (in some cases, there may be signs of rust or oxidation). Please check the photos for detailed condition. 3. Notes Import duties, taxes, and charges are not included in the item price. These charges are the buyer's responsibility.
