Yes, PAM 448. Yours has the plexi crystal, there was an option for Sapphire. I recall having the 425 slc pig dial with Sapphire, pretty expensive at around 500usd
yeah I think so too. I remember SF use to make 448, they had slightly better dial than ZF. Numerals/markers on this dial look slightly more creamy than ZF but it can be also the lightning pics were taken. I will check it out when I receive the watch.
In my opinion as well, and I'm pretty sure.
Two years ago I was looking for one of that kind, but stocks were already empty.
Don't know the situation at present.
