Get your hands on this serviced vintage Seiko 5 Sports Speedtimer 7017-6020 automatic flyback chronograph from December 1970 with original black dial, English-Kanji day wheel and 3-month functionality guarantee. Model history: The Seiko 5 Sports Speedtimer reference 7017-6020 is a highly distinctive vintage automatic chronograph from the early 1970s. It belongs to Seiko’s important first generation of automatic chronograph watches, a period in which the brand became one of the major innovators in self-winding chronograph technology. This model is powered by the Seiko 7017 automatic chronograph movement. The 7017 calibre is notable for its compact construction and flyback chronograph function, allowing the chronograph to be reset and restarted instantly with a single push while running. Unlike many later chronographs, this design keeps a clean dial layout without sub-registers, using the central chronograph hand together with the internal timing scale for elapsed time reading. The 7017-6020 is one of the most recognisable 5 Sports Speedtimer references, with its large stainless steel case, black dial, orange accents, tachymeter bezel and multi-scale dial design. The combination of the original black dial, Kanji/English day-date display and bold 1970s sports styling makes this a very collectable vintage Seiko chronograph today.
