I cut clock faces from catalogues. They always show ten to two, which I think is for symmetry. There are printable clock faces on the web, in any style and size, but as you know, I am a recycler. I have experimented with various ways to make simple clocks, using plastic rings, bottle caps and buttons. I use transparent file binders for "glass".
But if you want something more fancy, there is another well-known technique: tin can rings.
Again, I cut the faces from a catalogue. In the small openings I glued tiny real watch cogs. I think the effect is stunning. All in all it took me no more than an hour to make.
