About Watch-O-Scope – Watch Timing System

About Watch-O-Scope

Watch-O-Scope is a Windows software program
for diagnosing, testing, and regulating mechanical
watches. It is based on the same concepts as stand-alone electronic watch
timing machines, but uses the power of the modern PC to provide features that
mid-20th century watchmakers could only dream of. Watch-O-Scope is comparable
in features to very high-end dedicated watch timing machines costing thousands,
but at the price point of introductory level hobbyist watch timers.

To use Watch-O-Scope, you need a watch test stand. You can either
purchase a test stand, or you can
build your own.

Lite and Pro Versions

Watch-O-Scope has both basic features found in entry level stand-alone watch
timers, and advanced capabilities normally only found in high-end models. When
first downloaded, all features are available for evaluation for a period of 60
days from the date of first use. After that, Watch-O-Scope will continue to
work, but with only its basic features enabled (the “Lite” version), and may
continue to be used this way in non-commercial settings (for example, by a
watch 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 a
commercial endeavour (for example, a professional watchmaker) must
purchase an activation key for the Pro version.

Feature Overview

Watch-O-Scope is very easy to use. For basic watch timing operations, one need
only put the watch into a connected
watch test stand, turn it on,
and click one button. When needed, an intuitive user interface also gives
access to a variety of more powerful features.

  • Numerical display of daily rate error, balance amplitude, and beat
    error.
  • Horizontal “paper tape” mode with sub-pixel vertical resolution that
    can show fluctuations that are too small to see on a typical
    stand-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 made
    by the watch during each complete tick interval, giving unprecdented
    insight into the performance of a watch.
  • Long term testing to show long term fluctuations and perform power
    reserve 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 more
    meaningful reading than just naively averaging the rate.
  • Automatic signal and noise level determination. Usually, there’s
    nothing to adjust, although manual adjustment is possible.
  • Aggressive noise filtering in the software to keep the hardware
    simple for those who wish to build their own.
  • Automatic detection of common rates (18000, 19800, 21600, 25200, and
    28800 beats per hour), with support for manual entry of any rate from
    300 to 43200 beats per hour.
  • Simple, uncluttered, fixed-size display (1024 × 600).
