hello looking for a roller table for a 7ak & 8ae/ac..please pm me if anyone can help...thank you...
The Bulova 7AK is an ETA 735, which uses roller 41R in the master roller system 82S. It doesn't appear to be interchangeable with any other roller for any other movement, so you might be stuck getting the one for the 735, which is the base calibre for the 717, 790, etc.
The 8AE has no ebauche listed, so may be an in house calibre? Anyway, its roller is almost, but not quite the same, differing in height.
You would have to order both these parts from Borel or Frei or Cousins. Some of these parts can get expensive. I just ordered a roller for an old IWC and it was $82. Bulova and ETA parts are a bit more reasonable, but you may be surprised. If the part is no longer available, you may have to scavenge from other identical movts. This is a time honoured tradition amongst watchmakers, and is also why watchmakers end up with cabinets full of broken movts and parts. With Bulova, there are a lot of the same movts around in other Bulova watches, so this may not be as hard as you might think.
