Identify this Gen Rolex Bracelet?

[Esavy]

I went to my local watch smith today to resize my mothers watch. I saw this in the display case and snapped some photos. Can someone identify if its in fact;
1) Genuine Rolex
2) Which model does it fit? Pretty sure older model because of the clasp style
There is a number engraving on the inside of the end-links (045) I tried to capture unsuccessfully. Also, what's a good price to pay for something like this?

Thanks guys!

Its an older Oyster Bracelet

What model watch does it fit on? Datejust, sub? Any idea what would be a good price for it?

You need to ask the salesperson-it's prolly a 20mm. There were some 19mm made, but more than likely a 20. 20mm bracelets will fit on almost all men's size Rolex watches. I think there were some models that took a 19mm bracelet, but not sure which ones. Anyhone else got a clue on this?

I think the 19mm models were for the older daytona models, and also some of the older datejust.

And the 20mm models were for Subs like the 5513 and the GMT 1675, not 100 percent sure though.

Just adding that it's been over polished, and the end links that are on it are rep or aftermarket.

I honest think its a rep clasp.
the " butterfly " wings ( I don't know how to describe it as)
is incorrect.
the left and right side should have curve different in gen.
its hard to describe in words but you could search picture of rolex clasp logos , u will see what I mean.
