The invention discloses a double-escapement-regulator mechanical watch test method, comprising the following steps of: signal acquisition and signal analysis, wherein, the signal analysis includes initial watch-sound signal input and pretreatment S1; watch sound separation and analysis S2; automatic parameter adjustment S3; watch-sound signal input and pretreatment S4; watch sound separation and analysis S2; parameter computation S5; and screen display. The test method of the invention has the advantages that as watch-sound signals are effectively separated and the watch sound can be analyzedand displayed on a screen, the performance test of escapement-regulation mechanical watches can be realized, and the method of the invention has high precision, stable and reliable service and convenient use.
