Born from the prestigious **Suwa Seikosha** factory under reference **5606-7140**, this flagship model sat directly below the King Seiko line, combining chronometer-adjacent mechanical refinement with bold, forward-looking Showa-era styling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe High-Performance 25-Jewel Caliber 5606 Automatic Heart:\u003c\/b\u003e Powering this historic timepiece is the revered **25-jewel Caliber 5606**, an in-house automatic engine operating at a smooth frequency of **21,600 vibrations per hour (vph)**. Celebrated by vintage purists for its ultra-slim profile and exceptional daily accuracy, this caliber deployed a lavish **25-jewel specification** to control gear-train friction. It incorporates modern executive conveniences including **hacking seconds**, quick-set dual calendar functionality, and manual-winding capability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eArchitectural \"\"7140\"\" Angular Case Geometry and Facets:\u003c\/b\u003e The reference **5606-7140** is globally distinguished among vintage collectors for its striking angular case architecture. The solid stainless steel case features sharp, multifaceted planes and broad-shouldered lugs finished with zero-distortion mirror polishing inspired by Taro Tanaka's **\"\"Grammar of Design\"\"** principles. This low center-of-gravity engineering allows the watch to sit completely flush against the wrist, sliding effortlessly under a tailored executive cuff.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMasterful \"\"Weekdater\"\" Dial Harmony and Bilingual Utility:\u003c\/b\u003e The dial of the **5606-7140** is a study in 1970s visual elegance, showcasing a radiant canvas paired with **hand-applied, multifaceted hour indices** and razor-sharp hands that catch light with high contrast. Positioned neatly at 3 o'clock, the dual-calendar aperture houses a **bilingual (English\/Kanji) day disk** alongside a quick-set date wheel, perfectly anchored by the applied metal **\"\"LM\"\" emblem** above 6 o'clock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eAn Investment-Grade Masterpiece of Suwa's Automatic Heritage:\u003c\/b\u003e Manufactured in the milestone mechanical year of **1972**, the 5606-7140 25-jewel Lord Matic Weekdater remains a highly coveted, universally respected cornerstone reference for serious vintage Seiko collectors worldwide. It captures the exact historical moment where Suwa Seikosha perfected high-utility automatic daily instruments right before the global watch industry shifted toward quartz technology. Built to an uncompromising heirloom standard, it stands as an eternal testament to 1970s Japanese horological design.\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\/t1240260387.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.
