A mechanical watch's accuracy rate is not constant. It can vary depending on build quality, watch position, mainspring tension and even temperature. The Timegrapher X iPhone app is a unique tool that helps you find, observe and understand rate fluctuations that develop over time.
The "INSTANT" module shows how the watch is behaving in the short term, or "right now". It is very similar to a traditional timegrapher device, with the added benefits of a real-time waveform display and a high-detail diagram display.
The "LONG TEST" module is a graphical data logger, which helps you observe the long-term behavior of a watch. Various chart indicators are available, such as average rate, moving rate history, rate drift over time, and more. Long-term measurements for up to 12 hours can be conducted for in-depth analysis of the watch being tested.
