Hurrah! What a pleasant sound! It is pleasant to hear the musical sequence at every quarter hour and number of hours following the fourth quarter on tuned set of coiled wire gong. Nowadays these clocks are electronically imitated by some quartz clocks of Citizen, Seiko and Rhythm because they contains electronically recorded and programmed circuit board of sound chips connected to speaker. But they can't beat the real chimes of these types of clocks.
