hey omegasix,
It depends on what you will be doing and for what company; i work for an IB and trust me you don’t want to come day one as an intern with a Patek or a AP ROO. Also, if you work in a high paying environment a lot of the guys will know something about watched and will be able to pick our the Patek as a fake fairly easy (if thats something you care to avoid).
I would suggest a Panerai or a high end Rolex if your looking for something you would be able to pull off. Alternative, the Tudor BB
Avoid rose gold, as an intern ppl will know you cant afford it.
Hope that helps
