ANDREAS STREHLER

Andreas Strehler tackles this challenge with the new Lune Exacte (picture above), which has the first high-precision phase of the moon indicator, displaying the moon's age in days and three-hour intervals.

The Lune Exacte can be read and set right to three hours at any time, not only every fortnight, thanks to its unique and patent-pending system.

The watch contains a traditional phase of the moon indicator as well as an extra display based on a Vernier scale at 6 o'clock on the openworked dial.

The moon's age is shown by the red arrow in days. The new moon and full moon are shown by two red points on the scale. The precision of the indicator is increased to three hours thanks to a Vernier scale on the inner ring.

The moon's age is shown by the red arrow in days. The hours value may be read from the yellow sector of the inner Vernier ring if the arrow points to a number in the yellow sector of the outer scale. Where the next mark on the Vernier ring lines with a mark on the outer ring, the moon's age is given to within three hours. The 18 hours that must be added to the days are shown in the first picture on the left. The moon is 5 days and 18 hours old as a result.

Similarly, if the red arrow denotes a day on the blue sector of the outer scale, the hours on the Vernier scale may be read from the blue sector. The moon is 27 days and 3 hours old in the last image on the right.

All of this of the creation of the Lune Exacte was done in 2016, after that another creation was made in 2017 called the Sauterelle a heure mondiale.

Sauterelle à Heure Mondiale, with a local time indication and rapid setting, a GMT indication on a 3D northern hemisphere, a worldtime indication on a disc at the rear of the movement, and a phase of the moon indicator with a 1 day in 2 million year variation. The Heure Mondial also has a patented Remontoir d'galité as a Sauterelle (Below Picture).
