On my wishlist is a single hand watch from BOTTA which not only has only one hand but also has a 24h display -
see UNO24.

To check if I able to cope with this sort of watch I make a Windows 7 gadget of such a watch. The picture shows the watch at about 11:30 pm.
The gadget can be downloaded
here.
In the
source code repository also the svg files are contained, if you want to create your own design.
