My son has a Calypso watch model no. k55506/2 We have a problem to set the time. I search for Calypso and keep getting directed to Casio. Is a Calypso watch a Casio model? That's no problem. The problem is that even on the Casio site we can't find a manual or instructions to help reset the watch. There are four buttons. One is a light, one a stop watch, one switches between time and alarm and the forth I haven't yet worked out. I'm trying all combinations - please help or direct to site for manual for this watch. Thank-you

Every model changes the way time is set , the watch should of come with a manual, If not Google ( Casio watch manuals) then in the search window type in the watch model, click search, then down load it.

go to www.casio.co.uk go to support(methinks??) click on watches and put in the model number (the one you posted) and download the PDF manual relating to your watch (you will need adobe reader free download to read PDFs), this will be the full manual, once you figure it out DST will have to be on, as its summertime of course. ( i bought a wave ceptor for a fiver because the guy who had it didnt know how to recalibrate it after a battery change), a quick gander at the online manual put it right, there shouldnt be a problem setting it up again, good luck

This is suppose to be an auto setting watch, see Support FAQ link...
