Testing System

Precision with increased productivity

TAG Heuer has to guarantee Swiss precision even with increased productivity. Zühlke developed a quick, reliable and accurate testing system.

Customer Benefits

  • State-of-the-art solution in a minimum of time.
  • Zühlke expertise in the fields of optics, electronics and mechanics.
  • Best in class measurement stability and accuracy.

Task

TAG Heuer demands the highest accuracy and quality. The watch manufacturer checks the running precision of each movement several times during the production process. This check measures the frequency (± 0.1s / day) and the vibration amplitude (± 1°) of the balance. The frequency directly affects the precision of the time measurement; the amplitude is a benchmark of the assembly quality, which affects the power reserve and long-term accuracy of the watch. At current production volumes, existing measurement systems are too inaccurate and unreliable.

Solution

Zühlke devises a new measuring method and develops a customised measurement system. The test results were outstanding and exceeded the high expectations in terms of reliability and precision. Zühlke implemented the testing system in cooperation with the partners.
