Vintage Blue Omega Box

On offer's an old blue Omega box I've had for probably a decade without ever using (it came with a different watch, some local estate purchase). The pictures are probably the best description. I don't have much experience with vintage watch boxes, but this one seems fine—it opens and closes fine, the inside doesn't smell or have any marks that I can see, and the insert pulls out and fits in tightly. I have no idea what model this is for, though I'd guess a 1950s dress watch (feel free to let me know how wrong I am). It's available for $50 plus shipping. I can see these on ebay selling for more, but I'd rather someone who actually wants it gets it. Box/I are in Indiana/USA, and I'm happy to provide as many references as requested. Thanks to everyone for making this such a useful, interesting forum.
