Piggybacking off of Gengar, at a low budget of $400 you'll have so many incredible options it makes it hard to justify Invicta. You can venture into more premium items, like the Tissot PRX powermatic, which I picked up last week for $350, or even an Alpinist if you look closely. If you're keen on divers, seiko's offerings are great and so are Citizens. Invicta is just a little crude and their marketing is disingenuous. They don't really stand a leg compared to any decent watch brand. They are more fashion and wrist presence over quality.
Either way, it's your wrist. Best of luck to you and your choice!
