The reference **5606-7191** was produced by the **Suwa Seikosha** factory to capture the exciting, forward-thinking lifestyle shifts of the early 1970s. Explicitly designed for young corporate leaders and progressive professionals, it successfully provided an energetic, geometric alternative to traditional round profiles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Premium Upgraded 25-Jewel Caliber 5606 Heart:\u003c\/b\u003e This watch is powered by the rare, high-grade **25-jewel Caliber 5606**, an ultra-slim automatic movement operating at **21,600 vibrations per hour (vph)**. While standard mainstream Lord Matic models utilized a 23-jewel layout, this elite **25-jewel specification** was reserved for premium factory runs, deploying extra synthetic rubies to minimize gear-train friction and ensure extreme long-term daily stability. It features executive features like **hacking seconds**, manual-winding capability, and an integrated day-date display.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eArchitectural \"\"7191\"\" Fluid Tonneau-Cushion Geometry:\u003c\/b\u003e The reference **5606-7191** is highly celebrated among vintage purists for its distinctively stylish **tonneau-cushion case geometry**. Departing from conventional circular designs, the solid stainless steel case showcases sweeping contoured facets, wide integrated lugs, and beautiful mirror-polished edges that perfectly adapt Taro Tanaka's **\"\"Grammar of Design\"\"** guidelines into a softer, aerodynamic profile. This low center-of-gravity architecture minimized wrist fatigue while sliding effortlessly under a tailored suit cuff.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMasterful \"\"Weekdater\"\" Dial Legibility and Balance:\u003c\/b\u003e The dial of the **5606-7191** is a study in clinical mid-century luxury, showcasing a radiant silver sunburst canvas decorated with **hand-applied, multifaceted chunky block indices**. The dual-calendar window at 3 o'clock houses a **bilingual (English\/Kanji) day disk**, prioritizing instant everyday legibility for the globalizing Japanese workforce. The applied, interlocking **\"\"LM\"\" emblem** and the Suwa lightning bolt insignia at 6 o'clock remain proud hallmarks of pure manufacturing pride.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eA Landmark Milestone of Suwa's High-Spec Legacy:\u003c\/b\u003e Produced in the milestone year of **1973**, the 5606-7191 25-jewel variant remains a highly coveted, investment-grade reference for serious collectors who value the **\"\"Mechanical Golden Age.\"\"** It represents the perfect historical intersection where rugged daily durability met early-1970s geometric experimentation and elite, high-jewel micro-engineering right before the full quartz transition. It stands as a profound testament to an era when Suwa Seikosha built mechanical dress watches to an uncompromising industrial standard.\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\/f1233041983.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.
