School chimes, wishing for the old school bell

When I was at primary school, my friends (the only ones with wrist watches) used to ring the bell 5 minutes late.

In Korean schools it’s an electronic chime, selectable at some sort of control board. I guess they have a choice much like a cellphone has a selectable ring tone. Mostly nameless and tuneless, but I have heard the Oxford chimes being played before. My current school, what they have playing, is just plain terrible. I plug my ears everytime it sounds.
