Dial looks original (higher resolution pics would help to determine) but movement looks a bit rough and crown and crystal are replacements.
Shame about the case corrosion as the lugs don't look too bad.
Best advice I can give with these is to wait and pay the extra for a good original one as sourcing correct parts to put right a so-so example can be a fruitless/frustrating task.
Dial is fine. Crystal and crown are service replacements. Unfortunately the case and movement corrosion is a deal breaker. From personal experience, putting these right, even on a watch in better shape than this is exasperating.
