This is odd. I have a Sellita movement that adjusts via a lever that must be pushed to either + or - to regulate speed. I recently purchased a 65B001 accutron automatic with 26 jewels yet it has the screw type adjustment found on ETA movements. The second hand seems much smoother as well. What exactly do I have. I’m confused at this point. Was this a transitional movement or what? Does anyone know? Please help me figure this out. Thx, Jonathan Williams.
