Elgin National Watch Company
The Elgin National Watch Company Observatory is a historic building in Elgin, in the U.S. state of Illinois. It was built in 1910 to serve the Elgin National Watch Company two blocks to the west. The two-story observatory provided data on time that was scientifically accurate to a tenth of a second. Manufacturers could then produce a more accurate watch. The observatory was an important part of the company's legacy, and they even changed their motto to reflect this. By 1950, the Elgin National Watch Company could no longer compete with wristwatch companies. The observatory was donated to a local school district and became known as the School District U-46 Planetarium/Observatory. The building was added to the National Register of Historic Places in 1994.
