Seiko Institute of Horology / 8-day wind-up wall 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.

Seiko (then known as Seikosha) first manufactured a wall clock in 1892. It was an 8-day wind-up wall clock.
