Need help estimating the price 2846 model

The dial is very clearly not authentic, which makes it a much less valuable watch, and is worth effectively less than the sum of its parts. Hands are probably not original based on the coloring, so it is really movement + case. Case looks reasonable, so may be 1-$200 for that, and about the same of the movement, though the movement is a franken I suspect based on the inconsistent plating, so it is really only good for parts anyway.

SO, MAYBE $300 if sold together? Maybe a little better if you found someone needing the case and sold that and the movement separate.

Worn case with bad tool marks, very tired movement that's seen better days, very bad redial.
The watch is of no interest to serious Omega collectors.

Your bet bet is to eBay it at a low reserve and let it run.

I agree with the above, the value is greatly reduced by the condition. Especially the poorly repainted dial. Don't buy it, just move on and keep looking.
