Recognized among horology purists, everyday watch enthusiasts, and collectors by its popular series nicknames—the \"Essentials\", \"Classic Quartz\", \"Black Sapphire\", or \"Everyday Sapphire\"—this 40.2mm watch offers a masterclass in minimalist design and practical endurance. It pairs a solid stainless steel case with a radiant sunray black dial, applied silver-tone baton indices, faceted dauphine hands filled with LumiBrite, a framed date calendar window at 3 o'clock, an in-house Japanese quartz movement, a scratch-resistant sapphire crystal, a 100-meter water resistance rating, and a solid stainless steel construction. Perfectly calibrated for gentlemen seeking an ultra-reliable, sophisticated everyday watch that transitions effortlessly from formal business attire to casual weekend wear. The defining visual highlight of this SUR311P1 reference is its deep, light-catching sunray black dial face. Under changing light, the dial shifts between an inky jet black and an alluring dark charcoal tone, accented by high-polished silver-tone hour markers and matching faceted hands that ensure instant legibility. For low-light visibility, the hands and index perimeters are treated with Seiko’s proprietary LumiBrite compound. A neatly framed date calendar window rests at 3 o'clock, maintaining clean dial symmetry. Protected by a premium flat scratch-resistant sapphire crystal, the harmonic contrast between the deep black dial, mirror-polished bezel, brushed case shoulders, and solid stainless steel casing delivers a sharp, refined, and confident wrist presence. Beneath its refined exterior, the watch is powered by Seiko’s dedicated in-house Caliber 6N52 quartz movement. Engineered for dependable daily accuracy, this electronic movement operates with a standard rating of ±15 seconds per month. Powered by a silver oxide battery providing an approximate 3-year battery life, the Caliber 6N52 drives central three-hand timekeeping (hours, minutes, sweep seconds) alongside a quickset date calendar at 3 o'clock, offering instant \"grab-and-go\" convenience without the need to wind or adjust time after periods away from the wrist. The case is engineered with versatile contemporary proportions, measuring 40.2mm in diameter with an ultra-slim profile thickness of just 8.4mm, an ergonomic lug-to-lug distance of 47.0mm, and a standard 20mm lug width, ensuring a balanced, flush, and exceptionally comfortable fit on the wrist. Unlike many everyday watches in this price category that feature standard mineral glass, the SUR311P1 comes standard with a premium scratch-resistant sapphire crystal. Engineered for daily durability, the solid stainless steel case features a solid screw caseback that helps secure a certified 100-meter (10 bar \/ 10 ATM \/ 330 ft) water resistance rating, making it completely suitable for daily hand washing, swimming, and light aquatic sports. The timepiece comes completed on an integrated multi-link solid stainless steel construction, secured by a solid three-fold deployment clasp with a dual push-button release.\u003c\/p\u003e","brand":"MonaWatch","offers":[{"title":"Default Title","offer_id":54060353913146,"sku":"SUR311P1","price":615.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/5858\/3354\/files\/NewProject_a29079ba-2508-415c-bdca-b468081292b0.webp?v=1789348615","url":"https:\/\/www.monawatch.com\/products\/seiko-discover-more-sapphire-sur311p1-mens-watch","provider":"MonaWatch","version":"1.0","type":"link"}
