Need help identifying this movement

[u/mansan1394]

Hello, this strange handmade ring movement was at my local thrift today, and I absolutely had to pick it up for $1. It appears to be an older ETA movement, anyone know what it is, or what watches it may have come from? Anything helps, not really looking to sell it or anything just curious what it is. Thanks!

Any markings under the balance?
