You are looking at the Seiko Blue And Cream Wall Slave Clock. Slave clocks depend upon a master clock for the accuracy of its time. These clocks would be set up throughout the building/ship and would be electronically wired to a master clock that would ensure all clocks were at the same time. These were widely used in ships, businesses, and public schools.
This vintage nautical wall clock housing has a light blue enamel coating and the faceplate is cream in color. The face does not have a glass covering! When mounted to the wall it sticks out 2.5 inches. It is marked “SEIKO” and “Japan” on the dial face. It was made in Japan by Seiko, a company that dates back to 1881. There are multiple stickers in the interior: Secondary Clock, Mc-009, and inspection pass(1999)sticker.
The clock has a thumbscrew on the side which allows access to the battery mechanism inside. The clock takes one AA battery. We have tested this clock and it is in working condition.
