destros are pretty rare, even for panerai.
aside from the SEs, the only regular production now is the PAM219 44mm.
it won't wear too big, as it only sounds big. if your wrist is bigger than 6", u'll be able to wear it.
as for the strap, i think else from A/B series rubberised calf, the rest are not anything like kodiak.
but as usual, its really easy to buy a aftermarket strap for panerai. and takes less than 1 minute to fix it on.
happy hunting!
