Seiko Prospex challenges every limit with timepieces created to exceed expectations, engineered with superior style and innovative technology for the sea, sky or land. Driven by a heritage of iconic design, Prospex continues to keep going forward with excellence in precision timekeeping, crafted for the modern world. Based on Seiko’s Speedtimer chronographs of the early 1970’s, this powerful creation offers superior timekeeping combined with sporty elegance and wearing comfort. Providing chronograph measurement of up to 12 hours of elapsed time in 1\/8-second increments, the proprietary caliber 8R48 34-jewel automatic movement beats at a frequency of 28,800 vibrations per hour, with a power reserve of approximately 45 hours and manual winding capability. The movement incorporates a column wheel and vertical clutch mechanism allowing for smooth, stutter-free movement of the chronograph hand while providing long-term efficiency, reducing wear and tear, and maintaining the power reserve during chronograph operation. For reliable timing, the three-pointed hammer system ensures that all hands return to zero instantly and in perfect synchronization when the re-set pusher is pressed. The black dial, framed by a tachymeter scale for an authentic look, displays the word “Speedtimer,\" honoring Seiko’s sports timing legacy, and features subdials with a contrasting finish, a date calendar, and LumiBrite hands and markers for superio r visibility in low-light conditions. Crafted of stainless steel with super-hard coating for exceptional scratch resistance, this extraordinary watch is fitted with a sleek multi-row bracelet for a note of tailored luxury and includes a dual curved sapphire crystal, a secure screwdown caseback, and a tri-fold push button release clasp. 10 bar, 100M Water Resistant\u003c\/p\u003e\u003ch3\u003eTechnical Data:\u003c\/h3\u003e\u003cli\u003e\n\u003cb\u003eModel: \u003c\/b\u003eSRQ055\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCollection: \u003c\/b\u003eProspex\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eSub Collection: \u003c\/b\u003eSpeedtimer\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eGender: \u003c\/b\u003eMen's\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eDial Color: \u003c\/b\u003eBlack\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eStrap Material: \u003c\/b\u003eStainless Steel\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eStrap Detail: \u003c\/b\u003eStainless steel bracelet with super hard coating\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eLug Width (mm): \u003c\/b\u003e20\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eMovement: \u003c\/b\u003eAutomatic Chronograph\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCaliber: \u003c\/b\u003e8R48\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eMovement Detail: \u003c\/b\u003e\u003cbr\u003eCaliber 8R48\u003cbr\u003e28,800 vibrations per hour\u003cbr\u003e34 jewels\u003cbr\u003ePower reserve: approximately 45 hours\u003cbr\u003e\n\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCase Material: \u003c\/b\u003eStainless steel case with super hard coating\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCase Diameter (mm): \u003c\/b\u003e42\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCase Thickness (mm): \u003c\/b\u003e14.6\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCase Length (mm): \u003c\/b\u003e49.5\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCrystal Type: \u003c\/b\u003eDual curved sapphire crystal with anti-reflective coating on the inner surface\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eWater Resistance: \u003c\/b\u003e10 bar, 100 meters (330 feet)\u003c\/li\u003e\u003ch3\u003eFeatures:\u003c\/h3\u003e\u003cli\u003eProspex Speedtimer Mechanical Chronograph\u003c\/li\u003e\u003cli\u003eDesign inspired by Seiko's early precision chronographs\u003c\/li\u003e\u003cli\u003eClassic black dial with Speedtimer logo\u003c\/li\u003e\u003cli\u003eBlack Tachymeter bezel\u003c\/li\u003e\u003cli\u003eContrast in finish between the dial base and subdials improves visibility\u003c\/li\u003e\u003cli\u003eAutomatic chronograph with manual winding capability\u003c\/li\u003e\u003cli\u003eColumn wheel and vertical clutch mechanism allowing for smooth, stutter-free movement of the chronograph hand\u003c\/li\u003e\u003cli\u003eChronograph measurement of up to 12 hours of elapsed time in 1\/8-second increments\u003c\/li\u003e\u003cli\u003eLumiBrite hands and markers\u003c\/li\u003e\u003cli\u003eDate calendar\u003c\/li\u003e\u003cli\u003eScrewdown caseback\u003c\/li\u003e\u003cli\u003eTri-fold push button release clasp\u003c\/li\u003e","brand":"SeikoLuxe","offers":[{"title":"Default Title","offer_id":51954156732717,"sku":"SRQ055","price":2500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/7852\/7533\/files\/SRQ055_1.png?v=1775577069","url":"https:\/\/chawijewelers.com\/products\/prospex-speedtimer-mechanical-chronograph-srq055","provider":"CHAWI JEWELERS","version":"1.0","type":"link"}
