Got them both.......and I did have a genuine 5513 too......all at the same time......kinda' wish I'd kept the 5513, but, the SD rep was soooo good that I quit wearing the Sub.......and it had more than doubled in value from when I bought it in 91'.......so I sold it a couple of years ago.......the Marcello's quality is every bit the equal of ANY Rolex I've owned......and the bracelet is a hundred times better.........But, at 1k they are a bit over-priced now IMOP
