* 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. The Timegrapher X iOS app is a unique tool that helps you find, observe and understand patterns developing over time.
It fluctuates with build quality, watch position, mainspring tension and even temperature. This program uses sound analysis and listens to your watch, then reports information about how it is running.

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 speed of a mechanical wrist watch is not constant. Marcello Maminos Tg timegrapher ( is a fabulous piece of software you can use to maintain your automatic watchs accuracy or to diagnose and determine if service is needed. 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. Rate deviation measurement: Measuring ranges: ☙99s/d or ☙9.9s/d Resolution: 1.0s/d or 0.1s/d Amplitude measurement: Measuring ranges: 100°~360° Resolution: 1° Measuring of the be-at error: Measuring ranges: 0.0~9.9 ms Resolution: 0.1 milliseconds Lift angle: Measuring ranges: 30°~70° Default value: 52° Measure positions: 1-6 positions Line length: 480 points Measuring times periods: 2/4/6/8/12/20/30/60 seconds Language: Chinese, English, Japanese Display: color LCD graphic monitor, 480*272 pixels Working environment: 10℃~40℃ Relative humidity: 0~80% RH Item size: 185 * 120 * 40mm / 7.3 * 4.7 * 1.6in Item weight: 337g / 11.9ounce Package size: 230 * 210 * 195mm / 9.1 * 8.3 * 1.6in Package weight: 1379g / 3.I found this some time ago and foun dit very useful:įrequency, the vibration of a movement. Specifications: Plug: EU-plug, US-plug, AU-plug (optional) Main material: ABS Color: grey+black Measuring possibilities: rate deviation, amplitude, be-at error of mechanical watches and diagram recording of the be-at noise. Six kinds of testing positions can be adjusted, and the simulation sound can be played in the speaker or mute. The sampling period can be selected by 2 seconds, 4 seconds, 6 seconds, 8 seconds, 12 seconds, 20 seconds, 30 seconds, 60 seconds, and the average value of corresponding period will be regarded as the precise value of the watch.
For the conventional be-at, the instrument can automatically respond for the special be-at, can manually select. The instrument will automatically calculate the rate deviation, amplitude, be-at error, and display them by the data in real time select "☙9.9s/d" at item rate ranges for result display, which can make the accuracy of rate deviation up to 0.1s/d. According to different watches, the instrument will automatically adjust the optimal signal level during the test. Features: The frequency diagram of the watch can be displayed on the LCD screen. This No.1900 timegrapher is a precise mechanical watches test instrument, it is used for multi-testing by watch manufacturers and watch technician.
