Hi all, new to the hobby and planning on the PP Aquanaut on rubber for my first purchase. After reading, I'll probably be using Josh. In choosing a model, though, I've noticed that there seems to be two versions of this watch, with one labeled "V2". Is this to reflect changes in the gen that were carried to the rep, or is "V2" a more accurate rep? A little confused. Thanks for the help, glad to be here.
