I got a watch for xmas and I really like it but I would like to change out the strap for a thin rubber one to make it fit better and to make it lighter. I bought the strap and even an all black buckle but took it to my usual watch repair person and he was nervous about changing it out. Can it be done??? I called Nixon to ask and they were all "it would change the integrity of the watch, blah blah, we have a 4220 PU, but I tried to explain to them that the all black in 4220 doesnt come with a PU band! Its almost like I was insulting them by even considering it. Basically if anyone has any info to help that would be great. Anyone change a band on the 5130?
