What is the typical heart rate of a quartz watch?

The typical heart rate of a quartz watch is indeed 32,768 Hz. This frequency is derived from the properties of quartz crystals and their ability to vibrate at a precise frequency when electrically energized. The 32,768 Hz frequency was chosen because it's a power of two (2^15), which makes it particularly convenient for digital circuits.

When this high frequency is divided down through a series of binary divisions, it can be reduced to a 1 Hz signal. This 1 Hz signal can then be used to accurately manage the timekeeping function of the watch, ticking once per second to maintain the proper flow of time.

The other frequencies listed, while they may be associated with various electronic applications or systems, do not pertain to the standard operation of quartz watches and would not result in the precise timekeeping that quartz technology is known for.
