The reference **4823-8010** was produced by the **Suwa Seikosha** factory during the peak of the \"\"Quartz Revolution.\"\" At a time when quartz watches were still significantly more expensive than mechanical ones, this model was a prestigious symbol of ultra-modernity and Japanese technical dominance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Advanced 7-Jewel Caliber 4823:\u003c\/b\u003e This watch is powered by the **7-jewel Caliber 4823A**, a high-end quartz movement that offered a staggering accuracy of **±15 seconds per month**. In **1976**, while basic quartz watches were becoming common, the 48-series was a premium \"\"heavyweight\"\" movement featuring a **jeweled gear train** and a robust stepping motor. It was designed to provide the same longevity and serviceability as the finest mechanical watches of the previous decade.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Innovative \"\"Blinking\"\" Second Hand:\u003c\/b\u003e A unique horological feature of the **4823-8010** is its early implementation of a **battery-life indicator** and high-torque movement. The caliber is famous for its precise, dead-beat seconds hand that hits the markers with surgical accuracy. This tactile feedback was a hallmark of the King Quartz line in **1976**, signaling to the wearer that they were experiencing the world's most advanced timekeeping technology.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eArchitectural \"\"8010\"\" Case and Texture:\u003c\/b\u003e The reference **4823-8010** is celebrated for its stunning case work, which often features a mix of mirror-polished and brushed surfaces. The dial frequently showcases a **\"\"Sandwich\"\" or \"\"Textured\"\" finish**, a signature of mid-70s Seiko luxury. With its integrated bracelet design and sharp, masculine edges, the 8010 case perfectly embodies the **late Grammar of Design**, reflecting the futuristic and industrial aesthetic of 1970s Japan.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eA Landmark of the Quartz Transition:\u003c\/b\u003e Produced in **1976**, the King Quartz 4823-8010 is highly prized by collectors as a \"\"High-End Quartz\"\" icon. It features the applied **Double-Quartz logo** (representing the twin-quartz crystal technology era that followed) and the iconic \"\"King Quartz\"\" script. It stands as a testament to an era when Seiko proved that quartz watches could possess the same **soul, craftsmanship, and prestige** as their mechanical ancestors.\u003c\/li\u003e\n\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003cdl style=\"margin:0 0 34px 40px\"\u003e\n\u003cdt style=\"font-size: 24px;font-weight: bolder;\"\u003eFor more information, please look at the pictures.\u003c\/dt\u003e\n\u003cdd\u003e\u003cdiv style=\"margin: 14px 0 40px 0;\"\u003e\u003cimg src=\"https:\/\/nonkun.boy.jp\/img_ebay\/m1232435592.jpg\"\u003e\u003c\/div\u003e\u003c\/dd\u003e\n\u003cdt style=\"font-size: 24px;font-weight: bolder;\"\u003eNotes\u003c\/dt\u003e\n\u003cdd\u003e\n\u003cul style=\"margin-bottom: 18px;\"\u003e\n\u003cli\u003e\n\u003cb\u003eBefore buying.\u003c\/b\u003e\u003cdiv style=\"padding-left : 30px;\"\u003eThe vintage watches we sell are inspected and adjusted so they work fine.
