Saw this DeVille for sale but can’t find anything online that really matches…not sure if this even qualifies as “vintage”. Does anyone have any advice/thought? TIA!

Ran across this Longines Mystery Dial that I thought was cool, but I don’t know a ton about them. Obviously being front load I can’t see the movement, it does have a signed crown but does anything seem off? Anything I should check, and is $350 a fair deal?
