We considerably exceed the requirements laid down for chronometers by the DIN standard 8319. The outstanding accuracy of our chronometers is achieved by means of ultra-modern electronics with a selected artificially aged and temperature-stabilized 4.19 MHz piezoelectric quartz. As with all Mühle products, the readability of the timepiece stands in the forefront. Our chronometers have a clear non-reflecting face with a separate scale for the second hand, which moves smoothly without vibrations. The time can also be read when the lid is closed. The battery can be changed without interrupting the action: The chronometer will continue to run for at least 5 minutes and it is not necessary to reset the time. In view of its reliability, functional capability and easy handling, our nautical chronometer is also suitable for use in industry and research.
