Hey fellow Texan!

I am not familiar with this clock, so I am offering a SWAG.

Before doing any more power tests, I would check the continuity of the coil. Next I would look for a switch that is closed by the rotation of the pendulum. That switch, if it is there, would close the circuit through the coil.

It may not use a switch but instead there could be a magnet in the pendulum that induces current in a coil (not present in what you show) that, in turn, energizes the upper coil to give extra energy to the pendulum.  I would imagine a simple transistor circuit to do this.

After looking again at your pictures, it looks like there is a compartment that is in closed. Maybe the "intelligence" is in there, and maybe you just need a power source as you suspected. Can you open the copmartment and show us?

BTW, I suggest you move your question to the "all things clocks" section of the forum. You will likely get more visibilit and response.

Here, we like to learn a little bit about you, etc.

Sorry for my stream of consciousness...does it say "quartz" on the face of the clock?

is the word quartz found anywhere on the dial or did you make the assumption that it's a quartz clock?

usually electric clocks do not run on 9 V batteries because it has such an incredibly short life.

by the way this theory is conflicting with the original quartz clock.

but I do tend to agree with the theory that it's not quartz I've snipped out a section we need a much much better picture of this. looks like a coil some insulated components no circuitry, sets hidden in the base someplace which also indicates probably not a quartz clock.

bulova

I'm assuming it says Bulova on the dial but in your pictures I can see hugo hettich?

    • Hi Mike I did a ships clock a long while ago, not a Hermle though and without getting the beast in my hands to refresh my memory I can’t recall the timing.  This doesn’t help I know but will start the grey matter turning.
    • Of course it will continue Richard.
    • I have stripped and cleaned a Hermle ships clock. It was just oily, no major faults, and I reassembled it, following my photos in reverse order. The time train is fine but the strike train will not play the ships bell strike for half-past. Ships bells play a four hour sequence for the 'watches' and play double 'ding' for the hour and the double dings plus one for the half past (eg half past the second hour is 'ding-ding' 'ding-ding' 'ding'). Sounds complicated but it isn't really. The strike wheel consists of pairs of bumps (for the ding-ding) and no single bumps. There must me some mechanism on the half-past that lifts the strike lever over one of the bumps so only one ding is played. When I get to a half past, it still plays double ding. I have a feeling it is to do with the lever in front of the rack (there is a sprung attachment  on it) and the position of the wheel (to the right) with the two pins that lets that lever fall, but no matter where I place that wheel I cannot get a single ding at half past! Please can someone help with advice on positioning so I can fix this? BTW Happy Easter 🐣 
    • No it's not 52. I had looked at the Pocket Watch lift angles thread, which lists Elgin 6s as something really high like 62° but visually that is not at all what this watch is doing. I think 42° is more correct and that's where my machine is setup. The watch has a million problems but I have made solid progress. Impulse jewel replaced. Hairspring didn't match the balance (which also doesn't match the serial) but I got it down into range this weekend with 8 or 10 huge timing washers. Replaced the mainspring, balance and train are nice and free. At this point it is running consistently and in beat at about 160°, the third wheel has a bend that sends the timegrapher on a little roller coaster every 8 minutes or so. Remaining amplitude problems may be down to the escapement. The banking pins were way out and it didn't run at all before I started. It has one of the old brass escape wheels rather than steel, and I assume the faces its teeth are probably worn or scored in a way I can't yet fix (or see without a microscope). I know this watch is not going to run above 250° but I am going to keep trying to get above 200. But the best part about this watch? Some unscrupulous person stamped "21 JEWELS" on the train bridge sometime in the past, right on top of the Damascening. It's a 15 jewel movement.
    • I think it would rather be the blast of high current drain that would do the damage. But if used occasionally to maybe fix a mainspring or do dial feet it might be worth trying especially if the mainspring or a replacement couldn’t be found.    Tom
