IMHO the dial on the first example is almost certainly genuine, but poorly relumed. The bezel is also okay, infact its such a good example you would be forgiven for thinking it was a wrong 'un. Anyway its overpriced I think.
The second example has the rare early gilt dial which is nice. The lume could be better but looks original and its a shame about the cracked bezel insert. It's very common on these 300's. The insert is a compression fit and over the years they tend to shrink (possibly aided by exposure to sun and salt water) which causes them to split. It's a common misconception that the bezel inserts are poured resin or bakelite.
Here's one of mine, a nice example of the breed:
