What can you tell me about this Seamaster De Ville Daydate?

Hi all - let me start off by saying I have very limited knowledge of watches and am just trying to get started and learn more (please be kind and constructive).

I recently bought this Seamaster De Ville Daydate on ebay. I liked the look of it, put in a low bid, and ended up winning. I have no detail on the watch, no papers, and have found very little in my research. I’ve seen a few similar watches through Google images (mostly on jeweler sites) but it seems like most of the Seamaster De Ville Daydates are the Tiffany & Co. branded ones.

Can anyone tell me more about this watch? Is it authentic? Seems like it’s been recased at some point, and the crown is definately not original. I have not had it opened to see the serial number yet. It came with a non-Omega band, which I have swapped out for the rubber strap on it in the pictures.

Any help or info would be greatly appreciated!

Hello! This is American reference C6864 but this one doesn't look good and is a hard pass.

EDIT: sorry I just realized you bought the watch. Well. I hope it was a bargain. 😀

There is a Seamaster de Ville thread that can be a good reference for new Omega enthiasts:

Thank you both for the info. Experience comes from mistakes! The watch runs pretty well, fortunately, and did not cost me very much.
