The display shows only the time. The power setting is shown by the indentation on the lower dial. This can be hard to see under some lighting conditions, specifically because it's designed to trick people into thinking it's made of metal.
The analogy is more like web pages using scanned images of hand writing, which I'd also say is bad design.
Translated to web, you're basically saying "all websites should use a high contrast serif font at >16pt. to avoid people committing dangerous mistakes when reading instructions online" :)
