1556 movement: ideal amplitude
I searched the forum a bit and didn't see an answer to my question: What is the "ideal" amplitude for a 1556 movement (from an 1803 DD)?
I believe I read somewhere that the older movements don't have the same amplitude as more modern movements but i'm curious what you all think. Thanks! |

The vertical pic I took didn't save for whatever reason. But here is the horizontal. It ran for probably ten mins or so to stabilize.
Also, I think I need a bit of tape on the case holder. ![]() Sent from my Pixel 4 XL using Tapatalk |

Could use a minor adjustment of beat error but otherwise not bad. How's the rate change btw positions? (Dial up, dial down, crown down, crown left, crown up and crown right)?
