The ProofMaster tests the water resistance of watches conveniently with a fully automatic closing and test sequence. With its high level of operating convenience, the ProofMaster is the ideal tightness testing device for the following areas: watch service centres, watch retailers, watchmaking and watchmaking laboratories.

The new generation ProofMaster – more compact, faster, more accurate. The latest technology and smart algorithms are part of its DNA. Based on many years of experience, a device has been designed that is characterised by the easiest possible operation. It impresses with rapid and reliable tightness testing, small space requirements, optimal protection of watches against scratching and its ergonomic design. The ProofMaster can be used as a stand-alone device or in conjunction with the PC software WiCoTRACE 3. This provides additional possibilities for the measurement analysis and the professional administration of parameters and results, either locally or centrally. Connect a ChronoMaster to your ProofMaster and have your rate, beat error and amplitude displayed directly on the screen!
