Carrying reference **4823-8110**, this high-end instrument was manufactured by the legendary **Daini Seikosha (Kameido)** factory. Explicitly built to bridge the gap between mass-market quartz and elite luxury tiering, it offered ambitious Showa-era business leaders unparalleled accuracy, perfectly capturing the corporate confidence of the late 1970s.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Over-Engineered 7-Jewel Caliber 4823 Quartz Heart:\u003c\/b\u003e This watch is powered by the magnificent **7-jewel Caliber 4823**, a premium early-generation quartz movement boasting an exceptional accuracy rating of within **±15 seconds per month**. While later modern quartz movements were heavily cheapened with plastic components and zero jewels, this elite **7-jewel specification** features robust mechanical-grade metal gear trains secured by genuine synthetic rubies. It integrates high-utility executive functions, including an instantaneous dual-calendar quick-set and a hacking mechanism.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eArchitectural \"\"8110\"\" Fluid Integrated Cushion Case Geometry:\u003c\/b\u003e Unlike other variations, the reference **4823-8110** is highly celebrated among vintage purists for its distinctively sleek **integrated cushion case geometry**. The solid stainless steel case features smooth, sweeping contours where the lugs blend seamlessly into the main body, implementing Taro Tanaka's **\"\"Grammar of Design\"\"** guidelines in a futuristic format. Finished with a masterful combination of zero-distortion mirror polishing and precise brushed textures, this low center-of-gravity structure sits perfectly flush against the skin.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMasterful Textured Dial and Prestigious Double-Quartz Emblem:\u003c\/b\u003e The dial of the **4823-8110** is a study in clinical mid-century luxury, showcasing a stunning, deeply detailed **textured canvas (such as a fine linen, frost, or diamond-dust patterned dial)** that entirely eliminates glare. It is decorated with hand-applied, multifaceted indices and sharp baton hands with dark contrast tracks. Positioned proudly above the 6 o'clock mark is the applied **\"\"Twin Quartz \/ Honeycomb\"\" style single-crystal insignia**, which historically guaranteed its high-grade electronic pedigree, alongside a framed bilingual (English\/Kanji) day-date aperture at 3 o'clock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eA Landmark Cornerstone of Kameido's Electronic Legacy:\u003c\/b\u003e Manufactured in the milestone year of **1977**, the 4823-8110 remains a highly coveted, investment-grade reference for serious collectors who value the **\"\"Quartz Golden Age.\"\"** It represents the perfect historical intersection where traditional high-end Japanese case finishing met groundbreaking micro-electronics. Complete with its iconic applied \"\"GQ\/KQ\"\" stylistic crowns on both the original dial and the time-setting crown, it stands as a profound testament to an era when Seiko built quartz watches to an uncompromised, indestructible heirloom standard.\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\/1233596167.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.
