Welcome Rockaffela... Glad to see you here... dont mind those buggers who talk **** about your SA... I owned SA and that is a beauty...

HBB just recently went up sky high.. reason.. i dont know.. maybe because its so close as the gen ... Movement A7750 was not always praise highly.. but mine has never been having issue.. always treat me well.. maybe luck

If i am not mistaken... the HBB can be swap using gen 7750. Feel free to contact the dealers and ask them if they can do that special build for you. never hurt to ask...
