Small arduino board for displays

Hey!
I want to buy this, but i don't know, which arduino board will work or can be connected with the display (the display has also touch).

So my question is, is there any arduino board under 1.28 inch, which can be connected with the touchscreen above?

Hope to get an answer.

Uh, no. That would require a custom board with a qfn or smaller package if you want to stay with the envelope of the display diameter. Current watches use either BGA, chip only or chip on board hybrids to stay as small as possible. They are difficult if not impossible construction methods for hobby projects.
