I was informed that a lot of generic parts are now being made to accomodate for the lack of spares no longer supplied by Rolex themselves. I even heard that you can now get any generic parts for most older movements ranging from the ebauche to gears etc. On Friday, I met up with an old collector who showed me a Rolex movement made completely from gereric parts of which most of the parts are now made in China, being different from the legitimate generic parts offered by material supply houses. He showed me two movements and asked me to pick which was generic. I have seen so many in my life time and I could not tell them apart. He then pointed out the one which was generic and I could have fainted with shock. This makes me wonder, if this is happening, how does one go about telling the quality of what you get when buying genuine second hand or vintage and how does one go about distinguishing the inferior materials used? I am shocked
