This is the ETA 2836-2 based movement from an Oris big crown that came to me for repair with a damaged ratchet wheel and badly worn crown wheel post which required replacement barrel bridge.

I bought this same watch for myself. Shortly after buying it, the ratchet wheel on mine also lost a few teeth! Luckily, I had a spare 2836-2 movement and was able to swap wheels. This watch not only is notably stiff, when hand winding, the counterweight will not wind it up when it is in my watch winder. It's the only watch in my collection that cannot be wound in my winder!
