Seiko Institute of Horology / Alarm clock
The Seiko Institute of Horology (now The Seiko Museum) was opened in 1981 as part of a project to commemorate the 100th anniversary of the founding of Seiko. The museum displays research materials related to time and timepieces produced in Japan and other countries around the world.

The first alarm clock made in Japan was known as the "belly button type." The driving force was a spring, and the force generated by the unwinding of the wound-up screw was utilized.
Types also existed where an organ chimed.
