The pictures on the listing should tell you what you need to know, as they are completely representative of the watch once you get it in person. Very basic military style field watch. This is obviously a dark chrome plated alloy case, not surgical steel, but it looks fine. The printed dial is clean, crisp and easy to read. The lume isn't anything to brag about but it's ok (Only the hands glow). The fit and finish are more than acceptable for the $20 price point. The short lug to lug width makes this look slightly smaller on the wrist. It has a stated case diameter of 40mm, but wears more like a 38mm watch. The case is super thin, so an excellent choice to wear with long sleeves. The black dial version, if paried with the right leather strap, could almost pass for a very affordable dress watch.
Two minor nit picks are the very tiny crown and the short second hand that doesn't come anywhere close to reaching the minute track. Whatever. It's $20, so I don't expect perfection.
My only real complaint is the supplied NATO strap is very thin, stiff and flimsy. I replaced it with a silicone strap from Bison Straps and it looks and feels like a much nicer watch now. If it had a better quality NATO strap, I would have given 5 stars. As it stands, for the low cost, I am still happy with my purchase.
