The register hands have me confused at the momment. Valjoux name has been owned and part of ETA for many years.ĮTA now stamps their name instead of the VAL or "R" for Valjoux.ġ3.25 ligne, 17 jewels, Incabloc shock protection, manual wind, date sizes: Minute 1.20 mm, Hour 2.00 mm are etched in stone, while I've seen different listings for the sweep 0.25 mm or 0.26 mm. Valjoux Watch Movements For Sale, Swiss Made. Only a watchmaker who has learn how to do this sort of work will be able to help you.
We do not do and have no knowledge of this kind of work and there is no reference book that we can consult with in order to answer your questions on which movement to use in a certain case. Seek advice from or hire the services of a watchmaker adept at swapping and re-casing movements.
This will give you a very good approximation of the balance wheel’s amplitude.We have no knowledge about which movements might fit in certain cases. If you don’t know the exact lift angle of your watch, we suggest giving the default lift angle of 52 degrees.
Most common lift angles of movements are between 48 and 54 degrees. Knowing the lift angle, meaning the angle travelled during this time, the LEPSI – Watch Analyser is able to calculate the balance wheel’s amplitude. To calculate the balance wheel’s amplitude, the LEPSI – Watch Analyser measures the time between the first and third noise. The lift angle is used to calculate the balance wheel’s amplitude: This angle is given by the movement’s manufacturer. The lift angle is a geometric feature of a movement. The angle that the balance wheel travelled between the first and third noise is called the “lift angle”. The third and loudest noise is created when the escape-wheel meets the pallet. A second noise occurs when the pallet detaches from the escape wheel. The first noise occurs when the balance wheel’s impulse-pin comes in contact with the pallet forks. However, the sound of a watch’s beat is more complex and each “tick” is made up of three different pulses. Quote When listening to the sound produced by a watch, we only hear its ticking.
