The rivet bracelet looks like a good rep rivet, of which there are two I know of: ruby and the ones tripdog (I think) uses. The latter is more expensive. Not sure which one this may be.
As for the scratches/light gouges, hopefully someone with more experience chimes in. Never done it myself. But imo everything looks superficial so easy to polish off, though it might be expensive to fill in the two light gouges using something like laser welding (and to me, there's no need for that anyway)
