18kt Constellation education

I've never been a dress watch guy, but I have a chance to trade for this watch. Please tear it apart. I know I see talk of dial refinishing here, but it appears original to me. Is it? Any help is appreciated. And it's not mine, so feel free to be brutal. Would this be 36mm?


And why did this one sell for so little compared to others I see?

I’ll take a stab at this being a reference 168.010. I want to say de luxe (18k dial) but I am not sure as the markers seem too short and the onyx infill should be wider. The dial is original and not redone.
It’s well worn (maybe not polished) which is evident just looking at the case back. Case size is about 35.5mm.
The crown has been replaced and the seconds hand is a little short (or maybe just a bad pic as I can’t see the tip).
The bracelet is plated and looks well worn so possibly it’s lived with the watch for sometime.

The eBay watch is lightly polished and has the wrong crown but otherwise not bad at all. As you say it went very cheap.

Hands seem short on yours?

Obviously you've noticed that the bracelet isn't 18kt, but gold plated.

Only the seconds hand looks short imo.
