I promise I'll run out of questions on this topic. I just called Casio Parts and ordered a set of DW5600EB strap adapters to put a Zulu strap on my DW5600E. (Unfortunately, they are back-ordered a couple of weeks, but I can wait.) My question now is will the DW5600E head, with the Casio adapters, fit a five-ring Zulu strap or am I forced to use a three-ring. My concern is whether the head with adapters will fit between the two sets of metal rings on the five-ring. I noticed one of the manufacturers who make the aftermarket adapters stated that their's will not fit a five-ring. I was just curious if this is the same situation with the Casio parts. I would prefer to use a five-ring to make sure the watch head did not move on the strap, or should I even be concerned about that. Thanks!
