Omega WWW Dirty Dozen With Low Y-Number Serial

Hello,

I would appreciate your opinions on this Omega WWW with a low 303 Y-number. I found another example on German eBay, Y 2691, with a very similar (almost the same) dial and hand configuration here: https://www.ebay.de/itm/176657700905
If the one in question is a redial - would be by the same person.

Are the dial, hour and minute hands, and subsidiary-seconds hand correct for this version or production range - i cant find too many low low Ys? What would be a fair market value for the watch in its present condition?

The profile of the crown - that concave shape that comes up to the watch case - is very attractive. Whether its original or not, I have no idea, I just like how it looks.
