I had a brand new Hermle clock (model 22835-002114) come back because the customer said it would not chime. He sent the batteries with it, and when I installed them, the clock would not chime or keep time. The batteries checked good on the tester, but would not make the clock work. As an experiment, I installed two brand new Duracell C batteries. The clock worked perfectly.

Examining several brands of battery, one can see that the bottom (negative) contacts are made differently.

AA cells: On some brands, the contact extends downward from the surrounding plastic covering, and these work fine. On some brands, the contact is flush with the covering, and these may not work reliably or at all in some clocks. Two brands of AA Cell that work well are Duracell and Rayovac.

C cells: Testing has shown that Duracell batteries work very reliably in clocks. Their negative contact extends further past the plastic covering then on some other brands, ensuring that it touches the clock’s contact.

A customer received a new Hermle chiming wall clock, and when it chimed or struck, all the notes sounded bad because the hammers were too close to the chime rods. The fix was simple:

1. Tighten the four nuts on the back of the case,
2. Slightly loosen the two Phillips head screws on the back of the case,
3. Move the iron chime rod base so that the chime rods are about 1/16 to 1/32 inch below the hammer heads,
4. Securely tighten the two screws.

I recently added chime and strike sounds of many of the Hermle and Chelsea clocks to the Bills Clockworks web site. It was challenging to record the sounds and have them sound realistic. The microphone had to be located close to the clock (about 8″ away) or else too much background noise was picked up and the recording was not loud enough, but the closeness over-emphasized the mechanical noises from the movement (such as the click made near the end of the chime when the strike is being activated). In real life, the listener is not aware of these sounds when she is located several feet or more away from the clock.

A challenge was to make the sound buttons compatible with as many types of computers as possible. I did not want a sound player window to pop up, I wanted just a button that the user can click to play the sound. On some windows PCs, the user must give permission the first time a button is clicked. Macintosh computers that I have tested handle the sound fine.

Please test these sounds on your PC and let me know if they play. Also tell me the type of PC (Mac or windows), operating system (such as Windows XP or Vista), and the web browser (such as Explorer 6 or 7). You may leave a comment below.
