    My decagon cased hamilton 912 has a bent balance shaft. Any idea where to find one?

    Nothing on ebay now.

    Jules Borel has three listings for staffs for a Grade 912.

    I have no idea which one would be right for your watch. You'll need to have a watchmaker disassemble and measure the staff in there now.

    Hope this helps,

    Swigart lists the staff as part 3050, but given the various pivot sizes used in these you really need to leave this to your watchmaker. You should also have them look at the balance jewels, because often a drop causing a damaged staff will also damage the jewels. Depending on the serial number range the balance jewels can be bezel or friction set in these calibers.

    Honestly US made pocket watches can be a real pain for sourcing parts. Plenty of people sell parts for these, but knowing exactly what you need is the key. I used to buy from a fairly local supplier here (Uncle Larry's Watch Shop) but he sold off all his parts supplies and now only deals in used tools. Here is a page listing a number of suppliers for PW parts:

    Thanks. Its at the watchmaker. He couldn't find one so I told him I'd look around.
