Then it’s definitely mechanical! The main difference is if there is a spring drive in it that helps it tick away, or there is a quartz mechanism that (as it vibrates on a frequency) ticks the clock forward every second. So unless there is a battery in it that would vibrate the quartz, it is mechanical. This is the best way i can explain it.

But it’s pretty nice it didn’t fall apart in a few months. if you had it for years, i think it’s awesome! :)
