[Recommendation Request] Have a missing slot in my case

Not the most luxurious or expensive collection, but I'm pretty happy with what I have so far (except for my wife's Movado that she doesn't wear anymore).

And yeah, there's an open slot that needs filling.

I think I'm leaning toward a proper field/military-style watch, ideally under $500 (though I could stretch a bit).

Preferably from a brand I don't already own, with an Arabic dial. I'm not too picky about the movement.

I've checked out brands like Hamilton, Marathon, Vaer, Bertucci, and Timex, but aside from the Khaki Auto 38mm, nothing has really hit the sweet spot for me yet
