Key Features

The New Era of High-Precision Luxury (1976): In **1976**, the **King Quartz** represented the pinnacle of Seiko's quartz technology, succeeding the mechanical King Seiko legacy. 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.

The Advanced 7-Jewel Caliber 4823: 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.

The Innovative ""Blinking"" Second Hand: 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.

Architectural ""8010"" Case and Texture: 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.

A Landmark of the Quartz Transition: 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.
