It is for sure a KW-V6Fac due to the decorated A6407 movement
Anyway if you have made "a lot" of searching you should have found this answer in five minutes.
Just go to the website of some dealers like: Toro, TSwatch, Puretime....
Then search PAM 587.
You will get two models: SF and KW-V6Fac.
SF are fitted with P.3000 Clone movement and KW-V6Fac is fitted with the movement you are showing (no doubts)
