Help Authenticating PAM561

[calvinlgoh]

Hi guys,

Need help authenticating a Panerai 561. I've done some reading and managed to check of most of the items on the usual list but hope to have some of you panerai experts take a quick look.

All numbers match from Paperwork to watch case and movement.
Box has appropriate barcodes that matches serial.
Purchased from reputable but non-watch seller.

I can return if there are any red flags.

Thank you in advance!
