This is a good point. For example, Ubi here, has a very high-end, "franken" (made from parts, both gen and rep), whereas I for example have the more budget Planet Ocean around, the POrikka. This watch is a 42mm version and runs approximately $115 to your door. Excellent beginner rep, a must have quite frankly. However, if you want it to be indistinguishable from a genuine, you are going to want to go Ubi's route. I'm sure he will post a few pics for you, it is truly stunning.
Here is My $100 POrikka. On rubber, bracelet, and leather deployant.
Pardon my tendancy to get wild with the exposure.
