watch recommendations for me?

Hey, so I'm looking to get a new watch, but im kinda stumped on what should I be looking for.

I'm looking for a watch for under 3000€, automatic movement, used or new, with a metal case and strap.

Im also looking for a watch that would hold it's value and look classy. Whilst being good quality.

I've looked at different types of Tudor and Omega watches and absolutely fell in love with the black bay 54 in lagoon blue, but those seem a bit pricey still.

Any suggestions would be greatly appreciated since im bit of a newbie with this watch scene!
