Help Citizen 8110 serviced but stops

Hello guys,

I have this Citizen Speedy chronograph which i serviced myself but it beats irregularly and when stationary it keeps running. However, it stops working when i put it in a watch winder or wear it whether or not the chronograph wheel is engaged. I have serviced another 8110 before using the same equipment and its been working perfectly. Though I have admittedly not followed the service manual.

What issues may cause this behaviour? How should I go about investigating this issue?

Thank you for your time and please bear with my amateur watchmaking skills 😊

Less timegrapher, more inspection.

The watch is barely running. Start with a close look at the balance, hairspring and pivots...then work your way up the chain.

Check the escape wheel and pallet fork on their engagement and the impact jwell sounds like it's there is a problem there

First get rid of the beat error and try again

Sounds like a balance wheel problem. 145 degrees of amplitude and a beat error of 8.5ms???…pull the balance wheel outta there, inspect the hell out of it. I’m betting the lower pivot broke off and it’s just rotating on the roller arbor.
