A 200 m rating is a static pressure test by the manufacturer. ISO 6425 certification adds tests for each individual watch (not a sample): water resistance at 125% of rated depth, condensation, shock, magnetism, strap strength and legibility in the dark. Our table gives an ISO 6425 diver 20 points for water resistance against 17 for an uncertified 200 m watch.
Under $300 the automatics (Orient Kamasu, Mako, Invicta Pro Diver) give you a mechanical movement with 200 m; the solar Citizen Promaster and Seiko divers give you ISO 6425 and a battery that recharges from light; the quartz Casio Duro gives you 200 m for the least money. Spec points per dollar settles the order; the type decides the ownership experience.
