1926 Bulova Conqueror

Hi again with another project for a friend. I'm restoring a 1926 Bulova Conqueror with the center wheel broken. Although I turned a 10AN center wheel axis and the watch runs correctly, now I need to repair the setting lever too. So, I think it would be a good idea to obtain these original pieces. Any help?

Best regards.

Is the movement 10AN, 10AP or 10P?

Sorry, 10P

Well. I have repaired the setting lever, so I would need only an original center wheel.

I bougth a broken 10AP movement and I'm reparing two movements (10P/AP) using 10AN pieces, so I don't need the 10P center wheel. As soon as possible, I will explain this reparation because I think this will be useful for the forum's members.

Best regards.

The 10AN is such a great movement. Glad you were able to use one as a donor for other movements. I look forward to hearing more about your experience.

These are the modifications I made to use the 10AN wheel in 10P/AP movement.

New rubies for the axis

Resize the wheel. 8,18mm to 7,94mm.

Running.

That's some serious workmenship. Great job in resurrecting the movement. The 10AP/10P are very hard to find.

What do you mean by 'resize the wheel'?

Both wheels have different diameter (10P/AP: 7,94mm, 10AN: 8,18mm) so you must reduce 10AN's diameter to 7,94mm in order to avoid the first wheel pivot can break.

This 10P movement is for a Bulova Conqueror bought by a friend.

The 10AP movement was bought looking for pieces (without center wheel). If I can, I will use in a Bulova correct case.

Best regards.

Well, the Conqueror is finished, reparing and polishing the case, new crystal and hands and finally restoring the 10P movement.

Best regards.
