Product Description
This series 190 coil balance spring is stamped # 7 or 740. These springs are also known as constant force balance coils.
Good Idea!
Balances are sold individually, however, it is a good idea to replace both window balances at the same time. Pairing a new balance with an old one would cause the new balance to wear out faster.
