The first quartz watches were sold by Seiko in 1969-1970. The history of this company is also interesting.
In 1877 Kintaro Hattori set up a small watch repair shop that would become Seiko (in Japanese it means precision ).
For 15 years the workshop repaired watches and then began making their own watches because the Japanese time measurement system consists of dividing the day into equal units, from sunrise to sunset.
The advent of railways imposed the Western system of measuring time. Hattori died in 1934 without knowing the later success of the company he founded.
