Sourced from the legendary **Daini Seikosha (Kameido)** factory under reference **7625-8961**, this timepiece was engineered to deliver uncompromised automatic performance for the modernizing professional class. It represented a crucial technological step forward, transforming the wristwatch from a delicate dress ornament into a robust, high-utility lifestyle instrument.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Indestructible 17-Jewel Caliber 7625 Magic Lever Heart:\u003c\/b\u003e This watch is powered by the highly respected **17-jewel Caliber 7625A**, a robust automatic movement operating at a classic frequency of **18,000 vibrations per hour (vph)**. Famous for its ultra-simplified, highly durable architecture, this caliber leverages Seiko's revolutionary **\"\"Magic Lever\"\" self-winding mechanism** to maximize winding efficiency with even the slightest wrist movement. By deploying a reliable **17-jewel specification**, Daini minimized mechanical wear, ensuring legendary longevity and easy long-term maintenance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSymmetrical \"\"8961\"\" Case Geometry and Recessed 4 O'clock Crown:\u003c\/b\u003e The reference **7625-8961** is universally celebrated among vintage purists for its elegant, perfectly balanced aesthetic proportions. The solid stainless steel case features **wide, clean lugs and a smooth polished bezel** that captures light with striking vintage warmth. Adhering to early automatic pride, it houses a **completely recessed crown flush with the case at 4 o'clock**, visually signaling to the user that manual winding was completely unnecessary due to the high efficiency of the internal rotor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDistinguished Dial Character and Symmetrical Date Window:\u003c\/b\u003e The dial of the **7625-8961** is a masterclass in mid-century layout harmony, featuring a beautiful silver sunburst canvas with an outer-rim index ring that visually expands the dial face. It showcases **hand-applied, multifaceted rectangular block indices** and razor-sharp dolphin hands that catch light with high-contrast legibility. Symmetrically balanced by a framed calendar aperture at 3 o'clock, the face is proudly completed by the vintage **\"\"Calendar 820\"\" typography** and the Diashock protection signature at 12 o'clock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Sovereign Pride of the Engraved Dolphin Case Back:\u003c\/b\u003e Manufactured in the milestone mechanical year of **1965**, the 7625-8961 remains a highly coveted, investment-grade cornerstone reference for serious vintage Seiko collectors worldwide. The ultimate hallmark of its historic sports-utility pedigree sits proudly on the screw-down case back: a **crisply detailed, etched Dolphin insignia**, which historically certified its rugged daily durability and water-resistant status.
