My FF Milspec I is signed insid as R-570. The place where normally the AS Logo is, it is flexed out and R-570 is engraved/stamped there.
In my Blancpain Vintage Studio report the caliber onetime is named as R-570. At the final report it is named a AS 1361.
It is a hacking movement. The watch has an American military provenience.
What do you think?
