I am a little confused.   I just purchased a supposed DG3804B, it looks different to the 3804 that I purchased from Cousins a while back.   But it looks the same as the supposed 2813 that was in my cartel 1655 GMT Explorer I purchased recently?   Anyone know if there are any significant differences in these movements? As I understand, they are both 21,000 with no independant GMT hand setting and virtualy the same size.   If anyone can shed some light on my confusion it would be apreciat
