Happens to the best of us. Live and learn. I've f**ked up enough 7750s keyless to finally be confident now of removing the stem every time.
I reckon i stuffed up around 5 before I got used to it. LOL
My watchsmith can fix A7750 no problems. I'm just not sure about Sec@12 transfer gear but I think it should be fine as well. Not much different just a transfer plate. Vac doesnt add the extra jewel like Domi does.
If you got it direct from VAC send it back to him. Happened to me before and he fixed it. Damn hassle though.
Otherwise PM me. I have a rep friendly watchsmith in Sydney that is very good. Not sure if he will touch AP Sec@12 though. U can try. He done alot of stuff for me already.
All great reps mate. Look for one that stands out to you or better just buy them all.
I love the PAM359.....i will get a 251 as well beause of the gold hands
