Hi Roger, It is likely the center wheel assembly. It consists of two parts, the wheel with two parallel arms that grip the center post (of the assembly, not of the watch) via spring tension. This acts a cannon pinion does, there has to be some slip but should not be loose. If you take your center wheel assembly out and hold it in a pinvise, you should not be able to easily turn the wheel with your finger, there should be friction. If there is not, that's likely your problem. Mike
If it is the center wheel assembly, it is easily repairable. You can gently snap off the wheel off the cannon pinion, and then use your staking set to make the center of the wheel a bit smaller. Then you apply the smallest amount of jismaa lubricant to the part where the wheel will rotate on the cannon pinion and snap it back on.
