I need to order 2 balance replacements

Hi there. Your balance is showing some resemblance to our Series 395. This comes fully assembled with a 19-005 balance top and 15-001 bottom balance shoe. Have a look to see if your nylon fittings match up with ours. If so, then you will need to measure the metal portion only of your balance to get its length. There should also be a stamping or marking on the balance to determine which of our options to choose from for the spring strength. If you have any other questions or concerns about any of this, please don't hesitate to reach out to us.
