A breakthrough technology in a sleek design.

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.

A fundamental rethinking.

From the design to the final assembly, each phase of the development of the Accuracy Pro has been made down to the smallest detail, in a unique partnership between Petitpierre and H2i Swiss companies.

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.

  • Aluminum unibody
  • Soft-touch coatings
  • Zero-backlash positioning

For the Accuracy Pro, the Swiss start-up H2i developed a brand new electronic board based on the premium XMOS micro-controller, a flawless Hi-res USB audio processor.

  • Asynchronous USB clock (TCXO)
  • Bit-perfect audio PCM 192KHz
  • Crossplatform technology (Windows, iOS, Android)
  • Integrated 3-axis accelerometer

It’s all about being smart.
