Um... It's an Omega box. Would you have pics of the watch? (instructions for posting here). Assuming you did want info about the watch and not the box, I could be wrong! And mods, could we move this to the Vintage OMega forum too? Thanks!
Best bet to sell it.. find out the base price for one without the AMC logo based on the model. Then find a populated AMC forum and offer it at that price. It’s going to sell for less with that logo on eBay. AMC is a dead brand as you know but there are some die hard collectors out there.
