Key Features

The Golden Age of Executive Quartz Luxury (1977): In **1977**, the **Seiko King Quartz** stood as a premier status symbol for Japan's corporate elite and high-ranking professionals. The reference **4823-8130** was produced by the **Suwa Seikosha** factory during the absolute peak of the ""Second-Generation Quartz Era."" Having conquered global timekeeping with the quartz revolution, Seiko repurposed the legendary ""King"" nomenclature to represent uncompromising electronic luxury, offering the ambitious Showa-era executive unmatched precision and prestigious industrial craftsmanship.

The Over-Engineered 7-Jewel Caliber 4823 Heart: This watch is powered by the magnificent **7-jewel Caliber 4823**, a high-grade quartz movement operating with a clinical accuracy rated at an astonishing **±10 seconds per month** in 1977. Unlike cheap, zero-jewel disposable quartz movements of the later eras, this elite caliber utilized **7 synthetic rubies** to protect critical pivots within the heavy-duty gear train. It features a bilingual day-date calendar, excellent battery efficiency, and an incredibly crisp, authoritative stepping motor drive.

Architectural ""8130"" Grammar of Design Case: The reference **4823-8130** is a definitive and masterful execution of the legendary **Seiko ""Grammar of Design""** legacy adapted for the late-1970s. The stainless steel case features incredibly sharp, angular facets and wide, muscular lugs finished with mirror-polished flat surfaces that create a brilliant play of light. In **1977**, this substantial yet low-profile geometry maximized executive wrist presence while ensuring the watch sat perfectly flush and comfortably under a tailored dress shirt cuff.

Masterful Twin-Quartz Era Dial Texture: The dial of the **4823-8130** is a study in clinical mid-century luxury, often featuring a flawless sunburst silver canvas or an ultra-fine **textured linen/snowflake pattern** that creates incredible visual depth. This is paired with **hand-applied, multifaceted baton indices** with dark contrast inserts for instant professional legibility. The applied, prestigious **""KING QUARTZ"" text** and the iconic single-crystal quartz symbol at 6 o'clock remain proud hallmarks of an era that valued tech supremacy.

A Landmark of Suwa's Luxury Electronic Heritage: Produced in the milestone year of **1977**, the 4823-8130 remains a highly coveted, investment-grade reference for purist vintage collectors worldwide. It represents the historical turning point where advanced micro-electronics met the absolute pinnacle of traditional Japanese case-finishing standards.
