The Accuracy Pro is a high-end manual multi-position acoustic sensor which brings to an end years of lack of innovation in the field of watch measuring instruments.

The Accuracy Pro is made entirely in a high grade anodized aluminum alloy by Petitpierre. All sensitive elements potentially in contact with the external parts of the watch are coated with a soft-touch rubber. For the Accuracy Pro, a brand new electronic board based on the premium XMOS micro-controller was developed, a flawless Hi-res USB audio processor.

The Accuracy Pro comes with a newly developed Windows App which integrates all the features you need: realtime scope view, diagram display, dispersion over time, cumulated graphs, tabular and radar chart.

It is a stand-alone device. It requires no battery or power supply. Plug it and forget it. It is that simple.
