overall i like the design!
what i would change:
no roman numbers, it's to classic compared to the character of the watch
if possible use an other type of hands, these ones are a bit to simple for me
try to angle the sharp edges of the case, i know it gives a sturdy look but maybe you tried a bit to hard and it gives a bit of to much of an unfinished look (and by that a to cheap look IMO)
a 7mm strap would maybe just not be so comfortable, 5mm will do the job also

)
but hey .... it's just my opinion and you asked for it
