Key Features
  • The Zenith of 1970s Executive Style (1971): In **1971**, the **Seiko Lord Matic (LM)** stood as the definitive timekeeping companion for Japan's booming professional class. The reference **5606-7130** was produced by the **Suwa Seikosha** factory during a landmark era of bold design innovation and technical optimism. Positioned as an upgraded daily luxury watch just below the King Seiko line, it offered the ambitious Showa-era executive a perfect blend of high-end mechanical slimness and the expressive, light-catching aesthetics that defined the turn of the decade.
  • The Premium 25-Jewel Caliber 5606 Heart: This watch is powered by the **25-jewel Caliber 5606**, an ultra-slim high-grade automatic movement operating at **21,600 vibrations per hour (vph)**. In **1971**, while the standard Lord Matic models featured 23 jewels, this elite **25-jewel specification** was a distinct hallmark of mechanical status, utilizing extra synthetic rubies to ensure an ultra-low friction environment for the gear and complex calendar trains. It features premium functions such as **hacking seconds**, manual winding capability, and an integrated day-date quick-set for clinical daily reliability.
  • Architectural ""7130"" Faceted Crystal Case Design: The reference **5606-7130** is celebrated for its highly sophisticated, sharp case geometry. The stainless steel case features crisp, angular lugs finished with specialized polishing that beautifully implements Taro Tanaka's **""Grammar of Design.""** A defining characteristic of this 7130 reference is its pairing with a dramatic **faceted crystal (cut glass)**, which was a major luxury trend in **1971**—shattering and scattering light across the dial to maximize executive wrist presence while keeping a low-profile silhouette under a tailored shirt cuff.
  • Masterful ""Weekdater"" Dial Sensation: The dial of the **5606-7130** is a masterclass in multi-dimensional clarity, featuring a radiant sunburst finish and **hand-applied, chunky multifaceted block indices** designed to interact beautifully with the facets of the crystal. The dual-calendar window at 3 o'clock houses a **bilingual (English/Kanji) day disk**, prioritizing everyday corporate utility. The applied **""LM"" logo** and the Suwa lightning bolt symbol remain prestigious hallmarks of an era that valued bold industrial pride and meticulous attention to detail.
  • A Landmark of Suwa's High-Spec Mechanical Legacy: Produced in **1971**, the 5606-7130 25-jewel variant remains a highly coveted reference for collectors who value the **""Mechanical Golden Age.""** It represents the perfect historical bridge where rugged daily utility met avant-garde 1970s fashion and high-jewel micro-engineering. It stands as a profound testament to an era when Suwa Seikosha perfected the **""Deluxe Executive Daily Watch,""** creating a reliable and visually captivating masterpiece that remains as dignified and stylish today as it was over half a century ago.
