Abstract
A watch composed of at least one guide element, at least one time indicator element, and a dial interposed between the at least one guide element and the at least one time indicator element. The at least one guide element is movable as a function of time and the at least one time indicator element is magnetically coupled to the at least one guide element for movement with the at least one guide element to provide a detectable time indication. The watch is further provided with a cage space for maintaining the at least one time indicator element secure against loss, and the magnetic coupling between the at least one time indicator element and the at least one guide element extends over at least a partial area of the cage space.
