I already own the 309 as well, so this is basically just a dial change.
As has been stated below, the numbers will have the same patina as the 249, thus it will fit very well with the rose gold hands, ring and indeed the minerva movement is just about the nicest finished movement ever fitted into a Panerai. ( IMHO even more than the Angelus and Rolex because those were NOS, and although historically correct, i always personally hate "dirty" movements, from the years and such, plus i think because iv got allergic skin, im kinda traumatized)
Cheers!
