The Shepherd Gate Clock, installed in 1852, has a singular 24-hour dial based on astronomical time. It is the face of Greenwich Mean Time, now called Universal Coordinated Time.

GTG watches use a Sea-Gull movement. Twenty-four-hour movements are relatively rare; Sea-Gull looks like an excellent choice for the watch's movement. (I have a few watches powered by Sea-Gull movements; they keep great time.)
Kickstarter funding ends on December 23, 2015. For $188, you can acquire a 12-hour GTG watch, and for $196 you can invest in a 24-hour watch. (The prices are listed in British pounds, so the actual price may be a little different in your currency.) There are more expensive GTG Watch models, too.
