The average age of school buildings in the U.S. is 42 years old. Some facilities have wired clock systems dating back to the 1950's or earlier. For some, it's just a matter of time before the system master clock fails.

Choosing a master clock with an Ethernet option allows you to update your clocks and bells from any computer with an internet connection.
