The reference **5606-7150** was produced by the **Suwa Seikosha** factory during a landmark year when Seiko was redefining the \"\"High-Standard\"\" automatic watch. It arrived as a more sophisticated evolution of the early LM series, offering the ambitious Showa-era professional a level of finishing and mechanical reliability that rivaled the elite King Seiko line at a much more accessible price point.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe High-Grade 23-Jewel Caliber 5606 Heart:\u003c\/b\u003e This watch is powered by the **23-jewel Caliber 5606**, a revolutionary automatic movement operating at **21,600 vibrations per hour (vph)**. In **1970**, the 56-series was a breakthrough in slim-profile architecture, allowing the watch to sit comfortably thin on the wrist. It featured advanced functions such as **hacking seconds**, manual winding capability, and a dual-calendar quick-set—features that established the Lord Matic as a leader in technical convenience for the global executive.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eArchitectural \"\"7150\"\" Case and Modernist Aesthetics:\u003c\/b\u003e The reference **5606-7150** is celebrated for its sturdy and elegant case design, featuring sharp, mirror-polished surfaces and robust lugs. In **1970**, this design followed the \"\"Grammar of Design\"\" principles, emphasizing flat planes and precise angles to maximize light reflection. This specific reference was often paired with the era’s trend for **vibrant sunburst dials**, visually communicating the optimism and high-status energy of Japan’s industrial golden age.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMasterful \"\"Weekdater\"\" Dial Symmetry:\u003c\/b\u003e The dial of the **5606-7150** is a study in functional balance, featuring **hand-applied, multi-faceted baton indices** and the iconic dual-calendar window at 3 o'clock. The inclusion of a **bilingual (English\/Kanji) day disk** was a vital innovation in **1970**, prioritizing clarity for the internationalizing Japanese workforce. The applied **\"\"LM\"\" logo** and the Suwa factory symbol remain prestigious hallmarks of this era’s uncompromising mechanical pride.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eA Landmark of Suwa Mechanical Versatility:\u003c\/b\u003e Produced in **1970**, the 5606-7150 remains a foundational piece for vintage collectors who value the \"\"Executive\"\" lineage of Seiko. It represents the perfect intersection of **advanced mechanical engineering and bold 70s design flair**. It stands as a testament to an era when Suwa Seikosha perfected the **\"\"Slim-Profile\"\" automatic**, creating a reliable and stylish companion that remains as accurate and visually striking today as it was over half a century ago.\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\/x1223251236.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.
