What does everyone collect besides Rolex -

Just curious! I'm sure there are some folks out there who are exclusively Rolex, but I'm sure many others have interests in watches besides Rolex, as well. Although Rolex is definitely my favorite brand, I do think Citizen, although not a watch that most people would consider "upscale", per se, makes some nice watches, and I have a couple Eco-Drives that I really appreciate! I'm also looking to, hopefully in the near future, add an Armand Nicolet S05 basic to my collection, or perhaps a Doxa750T. I have other ambitions, like the Omega Speedmaster 50th Anniversary edition, as well as a couple other Rolexes, but those dreams will have to wait for now, as the majority of my fun money is tied up in a business investment...which hopefully will soon be providing the financial returns I need to pick up some even nicer pieces!
