The Le Régulateur Louis Erard x Vianney Halter is a collaboration between Louis Erard and the independent watchmaker Vianney Halter
A regulator is a watch with hour, minute and/or second hands that do not share the same axis. So, each hand has its own axis, and is therefor on another position of the dial than the other hands.
.
It’s a rather unique and highly legible way of displaying the time, where the hours, minutes, and seconds are shown on separate dials. This design was originally developed for use in observatories and workshops where precise timekeeping was essential.
