This landmark timepiece was the world’s first automatic chronograph to combine a column wheel and vertical clutch, setting the benchmark for accurately measuring elapsed time and establishing design principles that remain essential in high-functionality chronographs today.\u003c\/p\u003e\n\u003cp\u003eDesigned with clarity and performance in mind, the hard-coated bezel features a tachymeter for speed measurement, enhancing its professional tool-watch credentials. Beneath dual-curved sapphire glass, contrasting sub-dials sit against a black dial, using differing finishes to improve legibility while maintaining a refined, technical aesthetic.\u003c\/p\u003e\n\u003cp\u003eAt its heart, the SRQ055J1 is powered by Seiko’s in-house 8R48 mechanical chronograph calibre, housed in a 42mm case with a 49.5mm lug-to-lug length. This advanced movement combines a vertical clutch, column wheel and three-pointed hammer to ensure precise chronograph operation, smooth hand engagement and instant, perfectly synchronised resets. As part of the Prospex collection—short for ‘Professional Specifications’—this timepiece is engineered to be practical, reliable and durable, meeting the demanding standards of sports lovers and adventure seekers alike.\u003c\/p\u003e","brand":"Seiko Prospex","offers":[{"title":"Default Title","offer_id":52591173271818,"sku":"SRQ055J1","price":2400.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0926\/5276\/5450\/files\/seiko-prospex-mens-speedtimer-maximum-precision-mechanical-chronograph-watch-p53536-103287_image.jpg?v=1781638912","url":"https:\/\/www.francisandgaye.co.uk\/products\/seiko-prospex-mens-speedtimer-maximum-precision-mechanical-chronograph-watch-srq055j1","provider":"Francis \u0026 Gaye","version":"1.0","type":"link"}
