Thanks to a pf friend's interest which has now turned into MY interest lol....question on these watches... Can you buy other straps for them? I've seen a couple with the cute rubber strap for summer/beach...yet would like a leather strap as well - are they interchangeable? Would anyone want to post pics and let me know where they bought theirs? I have nothing around here but know of a couple on-line retailers along with NM... Thanks!
