====== Operating indicator ======
An **operating indicator** is a simple window, usually color-coded, which shows whether a watch movement is running or not.

The operating indicator can be tied to the main time display or a [[chronograph]] function. For example, the [[JLC 751]] uses a rotating operating indicator rather than a seconds hand to show that time is passing. In contrast, the [[JLC 975]] uses an operating indicator on the chronograph to show whether it is read, in motion, or stopped.
