If you've never owned a mechanical watch, I'd start with something like this to see if it's something you'd really like it/wear it.
Sugess is doing some awesome designs and uses a reliable movement. It's an awesome value at this price point, and is a better introduction to mechanical moon phases imo. AliExpress is selling it for like 190 right now. Just a thought if price is a concern.
I'm selling one here, I think this price is a reasonable expectation for grey market for this model, though less if you're not looking for full kit.
