A gauge for indicating a measured variable such as pressure. The gauge includes a motion detection device including a drive magnet that is adapted to be moveable in response to changes in the variable. The pointer rotation device includes a pivot member, a power magnet coupled to the pivot member, and one or more director members located adjacent the power magnet. Each director member includes a generally helical flange. A pointer is coupled to the pointer rotation device. The director members and the power magnet form a magnetic field adapted to magnetically couple the pointer rotation device to the drive magnet. The pointer rotation device is adapted to rotate about a rotational axis. Movement of the drive magnet in response to changes in the variable rotates the pointer rotation device and the pointer about the rotational axis such that the pointer indicates the measured variable.
