Hi guys, been having this issue for ever. My original New Haven Clock un my 57 goes too fast, like in 1 hr it’s 15 mins ahead of time. How can I tune it for proper timing?

Does your clock have an adjustment screw marked "S----F"?


Those who choose an automatic transmission want transportation. Those who choose a manual transmission want to drive.

There is a fast, slow adjustment in the New Haven clock. You can access it thru a hole in the back cover. I find it easier to remove the back cover and observe the screw used to adjust the fast/slow. Can't remember which way you turn the screw to go faster or slow it down. The adjusting screw is not marked inside the clock.

Forgot to mention that there's a little rubber plug that needs to be removed to see the adjusting screw. Mine was old and looked dried out so I put a little oil on it remove it.
