IWC Portuguese Model 371438 & 371447 - What's the difference?

[nasa]

Dear all sifus..

Can anyone kindly explain to me if there are any other major differences of these 2 model apart from the strap clasp (pin for 38 & folding buckle for 47).

371438


371447


Reason i'm asking is because the difference of pricing is quite significant between these 2 model. If only because of the strap then might as well just change the strap to the folding buckle then u get the more expensive 371447 model. What if u change it to after market strap?? What model should we call it then??
