I have this same clock but doesn't strike the 12 o'clock hour. I bought it at an auction for $50 not know that it was not working & didn't have a key. Found a local old timer that works on clocks & he got it going for me. I like the tone of the chimes the best on these clocks & I like that it uses a separate chime for the hour. Any idea on why it doesn't strike the 12 o'clock hour? I thought it was just designed that way. I'll probably just take it back to have the clock doc look at it again.
Those type of clocks are called 3/4 chiming clocks. 3/4 chiming clocks will chime the Westminster Quarters on the quarter past (:15), half past (:30), and quarter to (:45).
