This is the teleological argument that god exists based on perceived evidence of order in the universe. The idea is that a watch requires a watchmaker and that the universe is vast and ordered and it requires a maker. Another flaw is that the watchmaker doesn't make anything. An actual watchmaker takes the resources around him, the information or context around him and uses those parts and ideas to build a watch. It would seem that if this analogy is accurate then god assembled the universe from components around him and didn't create anything.
