• Upcoming updates
    Over the next couple of weeks we will be performing software updates on the forum. These will be completed in small steps as we upgrade individual software addons. You might occasionally see a maintenance message that will last a few minutes at most.

    If we anticipate an update will take more than a few minutes, we'll put up a notice with estimated time.

    Thank you!

Hi, I have just acquired an Elgin WW2 Aircraft clock. It only runs when it is face down - what is the likely cause please? Also it does not have a second hand - should it?
Thanks

Would be hard to tell without tearing it down and inspecting. Appears to be in need of service and cleaning anyway. And the balance staff might be missing a pivot on one side, causing it to run in only one position.

Usually this is indicative of bad points on the balance wheel arbor, bad cones if that's what it has, or bad jewels if that's what is used. As Dave said, you'll have to take it apart to see.
