Rolex Passion Report posts stuff like that all the time. There was one I think he posted which was even covered in flecks of welding solder. There's a fine line between something that tells a story and something that is wrecked, but Subs do seem to wear battle scars better than most.
Absolutely love seeing a well (ab)used working Rolex. Makes me want a Sub to wear as an everyday watch for work.
