Very nicely done! Clear, concise and informative! The measurements in other positions may vary
All the above recommended measurements are from that position. * Please note that if you are reading your QC from the dealer, you will generally receive only the results of the watch lying flat. Generally speaking to get a beat error of zero, the roller jewel in the pallet fork must be perfectly centered.Īsk for a different watch or have your watch serviced. The amount of time by which the duration of swing differs from one side to the other in the oscillation of a balance wheel. Amplitude can also fall as the watch winds down and the mainspring delivers less power.Īmplitude is a good indicator of the movements health and if is too high or too low, or that changes too much in different positions, can indicate a problem with the movement.Īsk for a different watch or have your watch serviced The measure of the amount of rotation in the swing of the balance wheel, in either direction.Īmplitude is higher when a watch is lying flat and usually falls when the watch is in a vertical position, due to increased friction. It is possible to adjust this yourself or ask your dealer to nudge it a bit. How fast / slow the movement runs (in seconds per day) Some other settings are present, for instance Gen co-axials angle is 30 degrees. Generally lift angles range from 44 to 58 degrees. Most modern watches have a lift angle of 50 - 52 degrees.
Important to be set correctly in order to calculate the Amplitude.
The angle the balance passes through while interacting with the pallet fork. This is a preset, depends on the watch you order. The number of balance wheel swings per hour or how many times the watch ticks per hour. So you've got the QC images or your brand new best replica, like, ever, with that incabloc you always dreamed of, as swiss as cheese, but what about your timegrapher results? What dahell are those?įrequency, the vibration of a movement.
