Clock Keys & Winders
A good fit starts with the details.
Use the original part and the movement markings to guide your choice.
Which details should I match?
Compare the full movement number, relevant measurements and the way the original part attaches. A clock’s brand or a similar appearance alone does not establish compatibility.
What if I am unsure?
Ask before ordering. Include the movement number, measurements and a description of the part you need. If photos would help, I can explain which views to send.
