UPDATE: The module defaults to midnight so I decided to remove the batteries at this time to get it to display the correct time, however once I had reset it back to default I was able to set the hour, date and minute without a problem

I did notice that the module only has very thin contacts, prongs of wire rather than flat copper plates, so I suspect that I was not being firm enough with the command buttons the first time around.
Anyone know what frequency the QC is on this watch, I think I recall reading that it different to the usual 32,768 Hz and the Hughes 786,432 Hz?
