Ok, taking vintage aside for a second. With random serials it is relevant. Also some serials are directly attaches to a certain physical aspect of the watch. Not all rolex 16710 where Pepsi . Rolex actually will only sell you a Pepsi bezel if they determine your specific serial or reference had it.

I just don't like making it easy for someone to attach one of my serials to a fraudulent post or fake watch. You want the serial, ask me, provided I have a direct email or number I'll give it to you. Is it an extra step maybe, but a sale takes a few back and forth emails or calls anyway so it really doesn't delay much. Nor does it make it any faster to post it.
