    Abstract: An electronic watch may include a housing, a display positioned at least partially within the housing, a transparent cover coupled to the housing and at least partially covering the display, a battery, and a coil coupled to the battery and configured to, during a battery charging operation, supply a first current to the battery and, during a haptic output operation, receive a second current from the battery to produce a haptic output. The electronic watch may further include a ferromagnetic element positioned at least partially within the housing and movable relative to the housing. The second current may cause the coil to produce a magnetic field, and the haptic output may be produced as a result of an interaction between the magnetic field and the ferromagnetic element that causes the ferromagnetic element to move relative to the housing.
