Clockpunk is a genre of science fiction similar to Steampunk that portrays advanced technology based on pre-modern designs, but the technology used is based on springs and clockwork. 

Some people consider clockpunk to be a sub-genre of Steampunk. 

Clockpunk can be divided into historical and non-historical Clockpunk. Historical Clockpunk explores how the world would have turned out if certain technological developments that occurred later had happened in the Renaissance and or certain inventions in the time of the Renaissance were created on a mass scale in the time period.Non-historical Clockpunk is set in settings similar to the Renaissance but on alternative worlds, planets, and the like.

This particular sub-genre can also overlap with the fantasy genre.
