Watch Timing Machine
Meet the Wei Shi model 1000 watch timegrapher machine. This is the affordable version of the well-known (and overpriced) Witschi timer. With this machine, you can see your watch’s beat rate, amplitude, beat error and more. It includes a multi-directional microphone for testing in various positions.
Note: If you want a watch timer that works with Co-Axial movements, you’ll want to go for this one.
