Autavia GMT serial number question


The Autavia GMT 11630 ( with the orange markings on sub dial) are stated “on the dash” to have serial numbers 337xxx or 345xxx.

But I have seen a couple starting 310xxx...

Serial 310xxx is stated on the dash to be the Autavia GMT with red hands.

Anyone know if the serial numbers on the dash are accurate, or almost certainly accurate? If so, the 310xxx serials with orange markings may be frankens?

I’m guessing it’s impossible to say for sure but would be good to know which is more “likely” - franken or not - in your opinion

Ta! 😊😊
