Excellent and cost effective machine. Adjustable lift angle compensation. Immediate display of watch escapement condition. . Shows loss/gain, beat error in milli-Secs, balance rotational amplitude in degrees and the beat speed in beats/Hr. The latter automatically and manually if required for odd beat watches. With experience of watch operation many other parameters of the escapement can be diagnosed from the readings taken by the Timegrapher 1900. As an amateur this machine will do everything that I need and should suit most "pro`s" as well. Just my opinion .

Great help for the watch collector and likely good enough for watch repairer as well. The watch test results were accurate, when compared to Elma 3 timegrapher (costing 10x as much). The only thing that I wasn't keen on was, that beat sound was generated electronically, instead of transmitted directly from the watch escapement.
