I have been trying to identify this Breiltling movement but I am unable to find a specific similar example even when searching the comprehensive Ranfft data base. I thought it might have been a Venus 188 or a Venus 175 but though similar the regulator arm is different from any Venus movement in the data base.
The maniplate has 165 stamped on it which is confusing as I am unaware of any Venus 165 movement.
Can I ask if you can identify this movement? Perhaps it is not a Venus and I am just fixating on Venus. I thinking that it is a 1950s/early 60s movement.
Movement on the left is definitely a Venus 188
