Key Features

The Pinnacle of Late-70s High-Precision Quartz Supremacy (1977): In **1977**, a landmark era when Japan achieved undisputed global dominance in timekeeping technology, the **Seiko King Quartz** stood as a premier symbol of corporate status and engineering pride. 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.

The Over-Engineered 7-Jewel Caliber 4823 Quartz Heart: 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.

Architectural ""8110"" Fluid Integrated Cushion Case Geometry: 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.

Masterful Textured Dial and Prestigious Double-Quartz Emblem: 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.

A Landmark Cornerstone of Kameido's Electronic Legacy: 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.
