Well, sort of but not really.
I created a new face from scratch, one that doesn't really exist. All created from components using photoshop.
The U-boat isn't a brand in any case, it is the name of a style range.
Nothing about that watch is real, although it looks it. U-boat is a term that can't be copyrighted/trademarked as it is general use.
The widget is good advertising for them and its use in an image can easily replaced with another more or less identical - see my panzer widget clock which is fundamentally the same face with an extra dial and the various components moved about.

Once again, it isn't a real clock image, it is has been hand-crafted digitally but it looks like it is real and on your desktop it operates like the real thing (if the real thing actually ever existed, which it never has).
