Thanks Echi! I do have 6 other watches but need to check off the Rolex itch and these 4 are the ones that have most intrigued me and fit into the rotation well!
I have always liked the Polar Explorer 2 Dials but recently the black dial and layout of the Explorer 1 is so simple but so pleasing..
I have also come to find that 39MM is a really nice fit on my wrist! I do need to try them on in the flesh but with Rolex that is pretty hard at the moment!
