Nice set of Casio's (and Missoni's). Yes always good to think about the local situation when going on holiday and be sympathetic to all's needs. To this aim, I always use the unassuming Casio W-800H when I go on holiday. It's just a shame that to my knowledge replacement straps for this particular watch costs almost as much as the watch itself!
I am really not sure; the SKX line, as far as I am aware, has been discontinued although I suspect there will be plenty of NOS for many years to come. Seiko appears to be re-positioning itself, hence the increase in prices but I am not persuaded quality has followed suit. Although the SKX served me well, my little £7, F-91W, was strapped to my stab-jacket and also regularly went to 50m with no ill effects, and kept better time!Missoni am I right in thinking that the SKX's successors arent ISO accredited?
