What is the lift angle for the Rolex 3235 movement?
That's what I said: the lift angle discussion approaches a 'dead end' since it is also not so important.
Any 32xx movement, which has low amplitudes after full caliber winding and/or looses quickly in amplitude, does that independant of 55 or 53 lift angles. So I don't really care any longer and use 53. I have shown that in many plots based on a bunch of data taken with my own watches. A wrong lift angle is only an offset for such curves. |

Thanks for the 8 steps you proposed, it's exactly what a watchmaker should do! In fact there are even youtube tutorials how to measure lift angles as you describe. Indeed I considered myself to try this with one of my watches but did not proceed because I don't want to open the caseback. I appreciate all constructive feedbacks as yours. |

Amplitude minimum is 200° after 24h in vertical positions Amplitude maximum is 310° at 0h (full wind) in horizontal positions Hope that's useful |

Longer answer is, all brands make mistakes in product development. A lift angle of 55° vs 53° is not a substantial difference so an error like that could have gone unchecked for a few years. Rolex, like all companies, are not infallible. It's conceivable that this was as simple as an error by the person who typed the original document. |

Yes, but keep in mind that the Delta is taken as a total maximum difference, meaning that you need the data of 0hrs and after 24hrs, and then see what the Delta is.

So the 53° is for all 32×× movements. If any changes were made to the escapement we would have a different part number for the escape wheel and pallet fork. Then a pallet fork would change from 3230-421 to 3230-421-1. They always add a '-1' to an existing part number when it gets updated, then the 'old' part will no longer be available in sav.myrolexnetwork.com. |

It could be that rolex changed the lift angle in document just to see that watchmakers make it run above 200 amp after 24h with the disadvantage of -12 amp.
= work harder to raise amp |
