The cartel seems to not like selling Noob products. I am assuming the "more reliable source" may be an H-Fac AP Diver? They've been butting heads ever since the PAM wars.
there's a possibility that the dial loosened up from the movement and is pressing against the seconds hand. I have this suspicion due to the fact that you mentioned that the mounting tabs were not present, it could've caused movement play in the case.
