Inspired by an influential SEIKO 5 SPORTS model from the late 1960s, this modern reinterpretation faithfully revives key vintage details, including the classic “5” emblem at 12 o’clock, the distinctive day-date display layout, compact case proportions, and bi-directional rotating bezel. The black dial gives this model a sportier and more versatile character while preserving the authentic retro atmosphere of the original design.\u003c\/p\u003e\n\u003cp data-source-line=\"16-16\"\u003ePowered by the proven Caliber 4R36, the SBSA313 features a Mechanical Automatic movement with manual winding capability. The movement operates at 21,600 vibrations per hour, uses 24 jewels, and provides approximately 41 hours of power reserve when fully wound. A stop-seconds function allows more precise time setting, while the day-date display adds practical convenience for everyday use. As a battery-free mechanical watch, it offers the traditional charm and engaging character appreciated by SEIKO automatic watch enthusiasts.\u003c\/p\u003e\n\u003cp data-source-line=\"18-18\"\u003eFrom a usability perspective, the SBSA313 is compact, wearable, and built for daily reliability. The 38.2 mm case diameter closely reflects the original vintage proportions, while the stainless steel bracelet, dual-curved Hardlex crystal, LumiBrite-treated hands, indexes, and bezel, screw case back, and 10 bar water resistance provide modern durability. This makes the watch suitable not only as a collectible display piece, but also as a practical daily-wear automatic watch.\u003c\/p\u003e\n\u003cp data-source-line=\"20-20\"\u003eLimited to 9,999 pieces worldwide, with only 1,000 pieces allocated to the Japanese domestic market, the SBSA313 is significantly more collectible than standard SEIKO 5 SPORTS models. Its black dial configuration gives it strong appeal for buyers seeking a rare JDM model with heritage design, mechanical performance, and authentic SEIKO character. This is a 100% authentic genuine SEIKO 5 SPORTS SBSA313, not a custom build, homage, or aftermarket reproduction.\u003c\/p\u003e\n\u003cp data-source-line=\"22-22\"\u003eRare JDM Limited Model \/ 1,000 Pieces for Japan \/ 100% Authentic Genuine SEIKO\u003c\/p\u003e\n\u003ch2 data-source-line=\"24-24\"\u003eKey Specifications\u003c\/h2\u003e\n\u003cul data-source-line=\"26-45\"\u003e\n\u003cli data-source-line=\"26-26\"\u003eCase: 44.7 × 38.2 × 12.3 mm, 137g, stainless steel construction\u003c\/li\u003e\n\u003cli data-source-line=\"27-27\"\u003eBezel: Bi-directional rotating bezel\u003c\/li\u003e\n\u003cli data-source-line=\"28-28\"\u003eBand: Stainless steel bracelet, one-push three-fold clasp\u003c\/li\u003e\n\u003cli data-source-line=\"29-29\"\u003eWater resistance: 10 bar \/ 100m\u003c\/li\u003e\n\u003cli data-source-line=\"30-30\"\u003eMovement: Caliber 4R36 Mechanical Automatic, manual winding compatible\u003c\/li\u003e\n\u003cli data-source-line=\"31-31\"\u003eFrequency: 21,600 vibrations per hour \/ 6 beats per second\u003c\/li\u003e\n\u003cli data-source-line=\"32-32\"\u003eJewels: 24 jewels\u003c\/li\u003e\n\u003cli data-source-line=\"33-33\"\u003ePower: Automatic winding with manual winding; approx. 41-hour power reserve\u003c\/li\u003e\n\u003cli data-source-line=\"34-34\"\u003eAccuracy: +45 to -35 seconds per day\u003c\/li\u003e\n\u003cli data-source-line=\"35-35\"\u003eDisplay: Analog black dial with vintage-style SEIKO 5 design\u003c\/li\u003e\n\u003cli data-source-line=\"36-36\"\u003eFunctions: Day display, date display, stop-seconds function, manual winding\u003c\/li\u003e\n\u003cli data-source-line=\"37-37\"\u003eSpecial features: Heritage Design Re-creation, limited edition case back, serial number engraving, screw case back, rotating bezel, special presentation box\u003c\/li\u003e\n\u003cli data-source-line=\"38-38\"\u003eIllumination: LumiBrite on hands, indexes, and bezel\u003c\/li\u003e\n\u003cli data-source-line=\"39-39\"\u003eGlass: Dual-curved Hardlex crystal\u003c\/li\u003e\n\u003cli data-source-line=\"40-40\"\u003eOrigin: Japan Domestic Market (JDM)\u003c\/li\u003e\n\u003cli data-source-line=\"41-41\"\u003eWarranty: 3-Year Manufacturer Warranty in Japan\u003c\/li\u003e\n\u003cli data-source-line=\"42-42\"\u003eModel Code: SBSA313\u003c\/li\u003e\n\u003cli data-source-line=\"43-43\"\u003eRelease Date: July 2025\u003c\/li\u003e\n\u003cli data-source-line=\"44-45\"\u003eLimited Edition: 9,999 pieces worldwide \/ 1,000 pieces for Japan\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-source-line=\"46-46\"\u003eKey Highlights\u003c\/h2\u003e\n\u003cp data-source-line=\"48-48\"\u003eThe SBSA313 stands out through its black dial configuration, giving the Heritage Design Re-creation model a sharper and sportier appearance than the silver-dial version.
