Created to compete with elite ultra-flat Swiss timepieces, the Liner line established new records for slim manual-wind case profiles in post-war Japan.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Ultra-Flat 21-Jewel Caliber 3140 (Liner) Engine:\u003c\/b\u003e Powering this historic masterpiece is the celebrated **21-jewel Caliber 3140** (often designated simply as the Liner movement), operating at a classic frequency of **18,000 vibrations per hour (vph)**. Measuring an astounding **3.2mm in movement depth**, this hand-wound engine utilized an over-engineered **21-jewel specification** and Suwa's proprietary **Diashock** shock protection to achieve extreme slimness without compromising structural stability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eArchitectural \"\"15016E\"\" Broad-Dressed Case Geometry:\u003c\/b\u003e Sourced in a refined stainless steel case, the reference **15016E** features long, sweeping lugs with sharp polished chamfers and an ultra-narrow bezel profile.

It showcases **hand-applied, multifaceted rectangular hour indices**—highlighted by an exquisite sculpted cross-cut index set at 12, 3, 6, and 9 o'clock—and razor-sharp dauphine hands, proudly signed in script typography with the classic **\"\"Seiko Liner\"\"** logo.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eAn Essential Pre-1964 Cornerstone of Suwa's Flat-Watch Heritage:\u003c\/b\u003e Produced during the founding golden era of ultra-thin manual-wind development in **1961**, the 15016E 21-jewel Seiko Liner is a highly coveted, investment-grade cornerstone reference.
