28 jan 1970 ano - The " Quartz Watch" was invented.

Descrição:

The first quartz watch to enter production was the Seiko 35 SQ Astron, which hit the shelves on 25 December 1969, which was the world's most accurate wristwatches to date. Since the technology having been developed by contributions from Japanese, American and Swiss, nobody could patent the whole movement of the quartz wristwatch, thus allowing other manufacturers to participate in the rapid growth and development of the quartz watch market, This ended — in less than a decade — almost 100 years of dominance by the mechanical wristwatch legacy.
