Westclox Big Ben Style Series

The Big Ben alarm clock was first sold in 1909 and has evolved through many case style and movement changes. There were 10 "mainstream" case styles of Big Bens, and additional case styles that have names instead of numbers.

Electric Big Bens were made in styles 5, 7, and 8. There are several other case styles of electric Big Ben.

When identifying a Big Ben style, observe the case shape and ignore the case and dial color, as some styles were made in various case and dial colors, as shown in the detail page for each style.
