 Dive into the infinitely accurate! The search for precision has been a catalyst for the development and the innovations in the watchmaking field since the 16th century.

From World War II, such precision has moved from watchmakers and astronomers to scientists: time is now defined through observation of physical phenomena and not through astronomical observation anymore.

The femtosecond – equivalent to 10-15 – (or a quadrillionth) of a second is the most precise fraction of a second ever measured. Such a degree of precision is imperceptible to human beings, but has nevertheless become necessary to daily life organisation: geo-tracking, transportation, telecommunications have become efficient thanks to this extreme precision.
