What time is it? Watches and horology

it's not the best example but it's cheap. I'd want to see a movement shot but if it were me I'd budget for a service and a replacement dial, though I quite like the original one it came with. Take care because that "original dial" has no date window which I'm struggling to make sense of. My guess based on these (shitty) pics would be that the second hand has been replaced (it should be red for the original dial) but the replacement dial is probably Omega manufactured and not redialled (though redials can be hard to spot without a higher resolution photo). It looks like the watch maker has put it together from spare parts to hand to keep repair costs down, but it looks reasonably legit.

This is what it would look like with the correct second hand and an original dial with a date window. To get it to this condition a replacement hand and dial, (or retouch the lume and go without a date window), service the movement and add a bracelet.

I think you should be able to get a better example for $450.

The seller is selling a bunch of watches so he knows what this piece is worth. It's no bargain. But unless the seller can give you more info as to why the "original dial" has no date window I'd pass on it unless you're super keen for a project.
