Hello, nice to meet you and thank you for the advice. I know that it is not easy and admire all of you who have not only the knowledge but also the courage to do so. The thing is I can never be satisfy with a rep. There has to be something wrong. And as my budget is not enough for me to attain the unattainable rolex, which has always been my dream watch, I decided to build one. Since I've been waiting for so long now, I think I'm prepared to mess up.
For now, I think I would not get that rep because the size is just wrong. Will find one that the size is right, maybe buy just the case so as to save money for the problems that may occur and will research more as you suggested!
Thank you
