The ProofMaster CP PRO does not need a compressed air supply thanks to its integrated compressor. Moreover, its smart test programmes, automatic test chamber and sensor actuation that all tightness tests can be carried out without a hitch. The ProofMaster’s high-performance testing algorithm delivers high precision and reliability.

A complete testing solution for boutiques and service: connect your ChronoMaster to the ProofMaster to analyse rate deviation, beat error and amplitude directly on your screen – and with the ChronoMaster Air, the process is wireless too. This enables you to deliver comprehensive watch testing with ease in both your shops and your service centres. The ProofMaster CP can work as a standalone device or it can be connected directly to a WiCoTRACE database. WiCoTRACE provides additional analysis and export features as well as professional local and central results management.
