I emailed casio support to ask them for an update to my watch the rangeman gpr-h1000 . I told them that 24 hour and military 24 hour are presented as 00:00 so when I see 0:00 and that's my 24 hour option engaged I feel like I'm getting a inferior product based on this. While the watch is great and everything else about it is brilliant this one feature is letting down my user experience and they need to address that.. who knows if we will get that extra 0
