Watch Escapement Analyser - eTimer See our new web site

Timegrapher Windows For Regulating A Watch Android An App In Google android an app known as Wildspectrum is certainly much less comprehensive but helpful for a quick check. If the quartz doesnt run, support or replace it, I did a few of Seiko A new158, poor battery leakage, somehow maintained to clear the circuits, both are usually running very. Patience is not always rewarded so handsomely, but it does favor the diligent watch adjuster. The Timing Traces. For the curious and the skeptical, here are the Timegrapher readings for all 6 positions. The watch ran for at least 30 seconds in each position, and the rate is based on a 12-second running-average window. If your watch is not keeping precise time, you can adjust the regulator yourself. A slight nudge toward the F (or fast) will speed the watch up, and toward S (or slow) will slow it down. Then let the watch run for a few days to see how much the rate was affected. Higher grade watches utilize a micrometer regulator and afford more fine control.

An advanced watch escapement analyser that allows accurate watch rate adjustments and diagnosis without the need for a traditional mechanical machine. It is used in conjunction with a special microphone to analyze the action of mechanical watches. It calculates amplitude of oscillation, daily rate, beat error, positional error and much more.

The system works for lever, co-axial and tuning fork escapements.

Clocks have not been neglected either. The truth of an escape wheel is analysed by plotting a histogram of the deviation of the tick from each tooth. The long term plotting function is great for assessing temperature stability. You can perform a fourier analysis in order to detect any periodic fluctuation. Allen deviation analysis gives a definite measure of stability. If you need to make wheels, see here.

Prices start at just £299 ($400).

Additionally, some versions of Windows need a microphone plug to be inserted into the mic socket before they will detect the sound system. Any stereo jack plug will do!

This software includes traditional machine emulations such as a simulated paper tape presentation, and takes advantage of the investment you already have in your PC. This solution will satisfy the most stringent requirements for mechanical watch servicing, diagnosis and quality control.

Featuring internet calibration, long term performance graphing with spectral analysis of cyclical variations, positional analysis with quality control statistics, and extreme flexibility in use, you will be able to achieve standards of measurement and diagnosis on a par with the most expensive instruments. This is a professional tool for all including the very best mechanical watches. Please arrange to call-in and try it.

The highly detailed oscilloscope display allows you to diagnose incorrect locking, inappropriate draw, lever horn rubbing on roller jewel, dart pin rubbing on safety roller, scored balance pivots, sticky hairspring etc. There is a wealth of information in that waveform!

£299 ($400) gets you a clip type microphone, with the full software. Please telephone to discuss other microphone options. I can provide conversions for most existing microphones. The clip-on microphone is rather special, featuring very low noise and exceptional high frequency response. It can be used either with the watch in its case or with the movement in a movement holder. However, this is by necessity a fragile microphone which might not be ideal for a busy workshop. The mic options are:

• 1. Software with clip-on mic, 299 GB pounds, $400
• 2. You provide a watch clamp microphone, Greiner, Vibrograf, Tickoprint, Witschi etc. We refurbish and modify it, and supply the software without clip-on mic for 349 GB pounds. (Other than UK, please contact Steve Lunn)
• 3. We provide a used swivelling watch microphone. We refurbish and modify it and supply the software without clip-on mic for 449 GB pounds. (Other than UK, please contact Steve Lunn)
• In the case of options 2 and 3, if you wish to add a clip-on mic at the time of purchase, there will be £75 ($95) to add. If you decide to defer the purchase of the clip mic, but want one later, it will cost the exchange price of £90 ($120)

Watch-O-Scope is a combination of hardware (currently DIY only) andWindows-compatible software for diagnosing, testing, and regulating mechanicalwatches. It is based on the same concepts as stand-alone electronic watchtiming machines, but uses the power of the modern PC to provide features thatmid-20th century watchmakers could only dream of. Watch-O-Scope is comparablein features to very high-end dedicated watch timing machine costing thousands,but at the price point of introductory level hobbyist watch timers.

Lite and Pro Versions

Timegrapher Windows For Regulating A Watch Band

Watch-O-Scope has both basic features found in entry level stand-alone watchtimers, and advanced capabilities normally only found in high-end models. Whenfirst downloaded, all features are available for evaluation for a period of 60days from the date of first use. After that, Watch-O-Scope will continue towork, but with only its basic features enabled (the 'Lite' version), and maycontinue to be used this way in non-commercial settings (for example, by awatch hobbyist).

Those users who wish to have continued access to the advanced features (the'Pro' version) after 60 days, or those who will be using Watch-O-Scope in acommercial endeavour (for example, a professional watchmaker) mustpurchase an activation key for the Pro version.

Feature Overview

Watch-O-Scope is very easy to use. For basic watch timing operations, one needonly put the watch into themicrophone stand, turn on theamplifier, and click one button. When needed,an intuitive user interface also gives access to a variety of more powerfulfeatures.

• Numerical display of daily rate error, balance amplitude, and beaterror.
• Horizontal 'paper tape' mode with sub-pixel vertical resolution thatcan show fluctuations that are too small to see on a typicalstand-alone timing machine.
• Scope mode to aid in diagnosis of various watch faults.
• Raw watch sounds mode, where the paper tape shows all the sounds madeby the watch during each complete tick interval, giving unprecdentedinsight into the performance of a watch.
• Long term testing to show long term fluctuations and perform powerreserve tests (Pro version only).
• A simple yet powerful and flexible report generation facility(Pro version only).
• Export of timing traces and long term tests as PNG image files(Pro version only).
• User selectable averaging period.
• Rate determination using linear least squares, giving a moremeaningful reading than just naively averaging the rate.
• Automatic signal and noise level determination. Usually, there'snothing to adjust, although manual adjustment is possible.
• Aggressive noise filtering in the software to keep the hardwaresimple for those who wish to build their own.
• Automatic detection of common rates (18000, 19800, 21600, 25200, and28800 beats per hour), with support for manual entry of any rate from300 to 43200 beats per hour.
• Simple, uncluttered, fixed-size display (1024 × 600).
