Serving as the modern, upgraded mechanical successor to the legendary SNK military series, this reference captures the rugged spirit, utilitarian functionality, and vintage field aesthetics of classic mid-century military timepieces. Across global horological communities, everyday carry (EDC) forums, and Japanese domestic market (JDM) collector circles, it has earned cherished community nicknames—the \"Field Sports Style\", \"5 Sports Field\", \"Khaki Field\", \"Desert Field\", \"Military Field\", or \"SNK Successor\"—for its textured matte black dial, vintage desert-sand khaki numerals, dual 12-hour and 24-hour military tracks, bead-blasted glare-free case finish, and ultra-durable woven nylon field strap. It unites a sculpted 316L solid stainless steel case in an ergonomic 39.5mm diameter with a high-contrast black dial face, bold Arabic numerals filled with LumiBrite, an in-house Japanese automatic mechanical caliber, curved Hardlex crystal glass, certified 100-meter water resistance, and an integrated khaki woven nylon strap construction. Perfectly calibrated for outdoor explorers, active servicemen, and discerning gentlemen seeking a dependable mechanical tool watch that transitions effortlessly from rugged backcountry expeditions and trail hiking to casual office environments and weekend adventures. The defining visual centerpiece of this SBSA117 reference is its purpose-built, matte-textured black dial face designed for rapid, glare-free time assessment under challenging field conditions. The dial features an inner 24-hour military scale nested neatly within prominent outer 12-hour Arabic numerals printed in a warm, vintage desert-sand tone. Both the primary Arabic numerals and the faceted matte syringe-style hands are generously treated with Seiko’s high-output LumiBrite compound, glowing vividly in low-light environments. A slender sweep seconds hand features a distinctive orange accent tip, providing immediate visual tracking against the dark background. Positioned at 3 o'clock is a framed day-and-date calendar aperture with a bilingual day wheel (Japanese Kanji and English on this JDM reference). Surrounding the perimeter is a fixed, bead-blasted smooth stainless steel bezel that flows seamlessly into the case architecture, eliminating distracting reflections in bright outdoor sunlight. Beneath its tailored exterior, the watch is powered by Seiko’s proven in-house Calibre 4R36 Japanese automatic mechanical movement, engineered and manufactured at Seiko’s dedicated horological facilities in Japan. Operating at a steady frequency of 21,600 vibrations per hour (3 Hz), this 24-jewel self-winding caliber harnesses the kinetic energy of the wearer’s wrist to wind the mainspring, delivering approximately 41 hours of autonomous power reserve on a full wind. The movement features automatic self-winding, manual hand-winding capabilities, an instantaneous day-and-date calendar mechanism, and a hacking seconds (stop-seconds) mechanism that halts the seconds hand when the crown is pulled out for down-to-the-second time synchronization. Built with Seiko’s proprietary Diashock shock-absorbing architecture, the movement delivers dependable stability rated to a factory precision tolerance of +45 to -35 seconds per day and incorporates JIS Class 1 magnetic resistance (4,800 A\/m), shielding timekeeping accuracy against everyday electromagnetic exposure. The case is engineered with classic, versatile field proportions, measuring an official 39.5mm in case diameter (39.4mm official specification) with a case profile thickness of 13.2mm, a compact 48.1mm lug-to-lug distance, and a standard 20mm lug width. When paired with its lightweight nylon strap, the entire timepiece weighs an agile 75.0 grams, ensuring an unencumbered, wrist-hugging drape ideal for active movement. The entire solid 316L stainless steel case is treated with a non-reflective matte bead-blasted satin finish that conceals scratches and withstands rugged abrasive wear. Dial protection is provided by a heavy-duty curved Hardlex crystal, offering enhanced impact resistance and vintage visual warmth. Built for active outdoor utility, the case features an oversized, easy-grip fluted crown at 3 o'clock and an exhibition see-through screw-down caseback that allows the wearer to view the mechanical balance wheel and decorated oscillating rotor, while securing an impressive 10-bar (100 meters \/ 330 ft) water resistance rating, making it completely safe for swimming, trail river crossings, heavy rain, and daily hand washing. The timepiece comes completed on an integrated, heavy-duty khaki desert-sand woven nylon strap fitted with bead-blasted stainless steel hardware and a secure pin buckle.\u003c\/p\u003e","brand":"MonaWatch","offers":[{"title":"Default Title","offer_id":67707992604986,"sku":"SBSA117","price":1250.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/5858\/3354\/files\/NewProject_d4455e9b-1971-4907-9749-14e0ad898be4.webp?v=1792086600","url":"https:\/\/www.monawatch.com\/products\/seiko-5-sports-field-sbsa117-srpg35-mens-watch","provider":"MonaWatch","version":"1.0","type":"link"}
