Yeah! That's what I've thought!
Which lead me to think that the Destro is pure marketing (to promote their history) and to make few K extra by just flipping over the movement (of course like you once mentioned, you have to have different case to fit the flipped-movement), has no technical different compare to 112 (am i right?)... and good that Panerai make it rare so that it's still consider good buy (collector item) if one bought it at retail price or with some discount... i remember once this model has been goreng up near 30K... honestly, i don't find that's worth it with the goreng price
Just my opinion la.. btw, i'm Panerai fans too
