[Recommendation request] New attorney. What watch should I get for the office/court that will also work for casual daily wear?

I’m new to watches and not sure what would suit my needs best. For now, I’d like to get one watch that will work both for a professional setting and for more casual use.

I’m open to all suggestions, but I think I want a diver watch that’s dressy enough for somewhat more formal wear. People in my office are not overly dressy day to day, but sometimes I will need to be wearing a suit for court.

I like what I’ve seen from Seiko’s Prospex line, for instance the SRPL5: https://www.seikowatches.com/us-en/products/prospex/srpl51

I’m hoping not to spend more than $600 right now. Any suggestions for what I should get?
