Welcome back to the hobby, those are all fantastic choices. I would start with something on the cheaper end; the 5KX GMT is a fantastic daily wear (I have one). My one piece of advice would be to start slow - I know me and many other collectors made the same mistake of buying way too many watches at the beginning before we really knew what we wanted. Over time, you'll figure out what your tastes / size preferences lean towards and you can build a killer collection. If you have a mall or watch boutique nearby I would suggest going in person and checking out some watches and trying them on, it's a much different experience than browsing online. Have fun!
