Sensors take accuracy to new heights in De Havilland pilot watches

Pilot watches made by Swiss De Havilland use VTI Technologies' pressure sensors for precision barometer and altimeter functions. The De Havilland pilot watches record times of take-offs and landings, flight duration, allowing the user to register both block to block and total flight time.

“De Havilland pilot watch models DH-01 and DH-02 have been developed specifically for pilots by pilots”, says Jean-Daniel Carrard, aviator and managing director of JDC Electronic SA. "De Havilland watches feature unique innovations that enhance flight data accuracy and usability of the watch. The DH-02 model is equipped with VTI's SCP1000 pressure sensor enabling altitude to be estimated to the accuracy of one foot. This entirely new interface, based on a rotating bezel, allows the user to adjust altitude and pressure (as in instrument panels) and to set the time – one of the intelligent features seen for the first time in the watch.  Also, a completely new proprietary control system based on the magnetic fields has been introduced to give precise control of the functions of De Havilland watches."

"We are excited to work together with JDC Electronic SA, a well-known design partner for several of the Swiss watch industry’s famous brands ", says Heikki Timonen, Product Manager for VTI's SCP1000 pressure sensor. "The demands for pressure sensors in high-end pilot watch are extremely high. Precise altitude information, stability and robust design are the key requirements for pressure sensor approval in this demanding application".

Taking the advantage of sub-meter accuracy of the VTI pressure sensor SCP1000, De Havilland watch keeps the aviator informed through several distinct modes: altitude (meters/feet), QFE height (hPa/Hg), Flight Level (FL), QFE and QNH (hPa/Hg) and barometer trend (hPa/Hg) information.
