The reference **5606-7050** was produced by the **Suwa Seikosha** factory during its debut year. It arrived as a high-end successor to the Lord Marvel, intended to provide the Japanese \"\"salaryman\"\" with an elegant, modern, and high-performance watch that could compete with the world's most sophisticated Swiss exports.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Revolutionary 23-Jewel Caliber 5606:\u003c\/b\u003e This watch is powered by the **23-jewel Caliber 5606**, an automatic movement operating at **21,600 vibrations per hour (vph)**. In **1968**, the 56-series was a breakthrough in engineering, utilizing a compact and efficient architecture that allowed the watch to be remarkably thin. This movement introduced high-end features like **hacking seconds**, manual winding, and a quick-set day-date mechanism to the mid-high range luxury market.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePurity of the \"\"7050\"\" First-Generation Case:\u003c\/b\u003e The reference **5606-7050** is a definitive example of the **early Lord Matic aesthetic**. The case features the sharp, mirror-polished lugs and clean lines that define the \"\"Grammar of Design.\"\" In **1968**, this architectural rigor was intended to reflect the \"\"sparkling\"\" success of the modern professional, offering a clinical and prestigious look that sat perfectly flush against a shirt cuff.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMasterful \"\"Weekdater\"\" Dial Symmetery:\u003c\/b\u003e The dial of the **5606-7050** is celebrated for its perfect balance, featuring a radiant sunburst silver finish and **hand-applied, multifaceted baton indices**. The dual-calendar window at 3 o'clock houses a **bilingual (English\/Kanji) day disk**, an essential innovation in **1968** for the globalizing Japanese executive. The presence of the \"\"LM\"\" applied logo and the Suwa factory symbol remain hallmarks of this era’s high-status branding.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eA Landmark of Suwa Mechanical Evolution:\u003c\/b\u003e Produced in **1968**, the 5606-7050 remains a highly prized piece for collectors as a **\"\"Year One\"\" example** of the Lord Matic lineage. It represents the successful bridge between the classic mechanical tradition and the modern, high-precision engineering that would eventually lead to the King Seiko 56KS. It stands as a testament to an era when Seiko redefined the expectations of the business class watch for a generation.\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\/s1223245572.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.
