I have an 8-day cuckoo, Regula 34 movement, that has a music box and dancers. All is working perfectly, except every few times (every few hours) when it is playing music there is a violent reaction of the chain/weight. It seems like it is getting hung up and then breaks free causing a jerking action. Upon closer inspection it seems that the chain doesn't quite catch a cog and then with a little more rotation of the wheel it falls back down on the cogs. I tried a new chain (Regula 8-day) and I confirmed it is not the chain. Below is a photo of the ratchet wheel. Looking for a new wheel there is one at Timesavers that seemed like it may work due to its description, but they told me it is not the right one for this application. Does anyone know where I can find a new wheel? Or, does anyone recognize this problem and can offer a tip to repair it??Thanks!!
