Watches

So I don’t actually only own 4 watches, as I have a couple of other pieces that I’ve either inherited or have been gifted to me throughout the years. However, these 4 are the ones that I have spent my own money on and what I would generally consider as watches that I have collected. The Casio was my first ever watch purchase, which I bought during a trip to Japan when I was maybe 13 or 14 years old. Never spent money again on a watch until I bought the Kanno at 22 as a little college graduation gift for myself and for accepting my first job offer as an RN. Randomly then bought the Timex a couple of months after that as more of a means to satisfy my “I really want another watch” itch, LOL. Fast forward to now at 26 having bought the Longines to commemorate being accepted to my doctorate program for nursing. My next watch purchase would ideally be for when I finish grad school in the next 2 or 3 years, and I’m open to any suggestions anyone might have on what watch I should get for myself by then. Thanks for your time!
