New Old Stock source
 

Where do people go to get New Old Stock source for Rolex 5513? Is there really a supply of this stuff around? I was talking to someone and he said in the 90s he'd go to watch making events and buy up lots of New Old Stock for Rolex parts. Is this stuff still floating around? I wonder how it would even get on the market, because I'm sure Rolex doesn't like this idea.
