TomThaMan Posted August 7, 2011 Report Posted August 7, 2011 Hi, While doing some work on my a7750 movement I accidently broke my balance wheel. It needs to be replaced, but my question is; can I use a genuine balance wheel assembly which is easily found on ebay? Or can i buy a new a7750 movement to use for parts? The watch is a Seamaster from perfect clones. Thanks!
Bike Mike Posted August 8, 2011 Report Posted August 8, 2011 What part of the balance did you break? The wheel? A pivot? If you broke the wheel itself, then you will need a wheel and spring as they are a matched pair, which means you have to transfer the balance staff and rollers...difficult to do without a steaking set The issue if you go with a ETA replacement part, like a full balance complete, it may or may not work with the hole & cap jewels. Heck, I have found there are enough variants with the A7750's, you might have the problem as well! Easy and cheap way would be to get it to a watchmaker that knows what he is doing...and his attitude. Some fo the old timers that have the skills to make things such as balance staffs from scratch wont touch a rep.
TomThaMan Posted August 8, 2011 Author Report Posted August 8, 2011 The pivot of the balance wheel is bend. I need a complete assembly anyway, cause I threw it away. Does anyone know if I can buy an a7750 movement somewhere?
Bike Mike Posted August 8, 2011 Report Posted August 8, 2011 eBay...But I belive they are the low 21.6K beat.
