Krayon is a Swiss watch manufacturer.
Watches that show the times of sunrise and sunset have been around before. But these needed a fixation on a specific geographic location in order to perform the appropriate calculation. Rémi Maillat, the founder of Krayon, set himself the task of creating a clock that would be free of this restriction, i.e. which can correctly display the sunrise and sunset times all over the world. He realized his vision with the model Everywhere, presented in May 2017. It is the world's first model with this capability.
The highly complicated watch has 600 components and three patents. You enter latitude, longitude, and time zone, and the mechanism combines this with the date and month to calculate the sunrise and sunset times.
