Hebdomas pocket watch
A Hebdomas pocket watch is a famous Swiss timepiece characterized by its eight day power reserve and a distinctive “open heart” design that reveals the internal balance wheel on the dial. Invented in 1888 by Iréné Aubry, the name “Hebdomas” comes from the Greek word for “seven” or “week,” highlighting that the watch only needs to be wound once every eight days.
