Identifying an original Longines vintage watch - military

So I’ve recently been learning and acquiring a few Longines tank and then I came across this “military” Longines. When I look at the dial, I’m pretty confident it’s a redial but when I open the case back I’m torn whether it’s genuine. It does show the Longines 7824411 and have the stamp near the lugs.

What’s everyone’s take on this?
