32.768 kHz crystals are one of the most common crystal units, used in smartwatches, clocks, digital calendars, meters and anything that needs to count time. The frequency 32.768kHz = 2^15Hz is easily divided into 2 (15 times) until getting a 1Hz signal, this provides an accurate 1 second clock signal which is perfect for Real Time Clock applications.
