Known for its innovative flyback feature, the Seiko 5 Speedtimer 7017-6020 is an unique chronograph that was first released in the early 1970s. This feature is perfect for continuous timing because it enables users to reset and restart the timer with a single press. The 7017 movement powers the watch, which is notable for its minimalism and emphasis on usefulness over several sub-dials. Collectors and enthusiasts found it appealing due to its simple appearance and Seiko's reputation for durability.
The 7017-6020, which was mainly released for the Japanese domestic market, is part of Seiko's range of automatic chronographs, which were first produced to compete with rivals from around the world in 1969–1970. During this time, Seiko was also at the forefront of quartz movements. In contrast to the bulkier chronographs of the time, this model stands out for having a very thin profile. The Speedtimer 7017-6020 is still prized by collectors today for its accuracy, unique mechanics, and scarcity. It marks a significant period in Seiko's history by fusing the technological innovations of the 1970s with the brand's heritage of affordable perfection.
