If going with the mainspring replacement because the clock is still in good shape or out of production new, then if you choose to send the entire barrel with the mainspring in it, we can swap it out for $30.
We will take out the mainspring and measure the width / thickness and approximate length and then install the correct spring back into the barrel.
If doing this please send to Clockworks PO Box 339 Huntington MA 01050 with your contact information.
It may be best also to send us an email to [email protected] so we can look out for the package.
It will end up being the 30 charge, and then add the price of the mainspring as stated in the below chart, and then shipping back to you.
If you would like to send in your barrel with the broken mainspring, please fill out the form at this link so we know its coming into us.
