# Best automatic dive watches under $500 Source: https://lumeandbezel.com/best/best-dive-watches-under-500 Publisher: Lume & Bezel. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://lumeandbezel.com/how-we-pick Plenty of watches under $500 look like divers. Fewer are sold as real dive watches. The difference shows up in the listing: an ISO compliant or ISO scuba approved claim, a 200 m rating described for diving, a screw-down crown, a unidirectional bezel and lume on the hands and markers. Some listings rate a watch at 200 m but then say it is not meant for diving, which matters if you plan to take it underwater. This guide compares seven automatic divers priced from about $200 to under $500 by ISO claim, water resistance, case size, crystal and movement. Everything comes from the product listings. Where a listing does not mention ISO 6425 or a spec, the table says Not stated, so you know what to confirm before you dive with it. ## Picks ### 1.
