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?

      Seitz Tool - Help determine if Seitz or not

      By Hawaiikook808 · Posted

      Thanks, ManSkirtBrew.  I started looking for a setup like yours and ran across this.  It was about half the price of the JKA Feintaster (depending on what auction you were in), and it's a Bergeon.  I bought it because I thought the price was fair (eBay - Buy it now), and I'm a sucker for vintage tools. It also has a table, so it should be easy to use for measuring jewels. I wonder if the the contact points can be changed out. Bergeon seems to manufacture new tables and accessories for the contemporary dial version. What do you guys think of it? I'm sorry this post seems to have taken a detour. I'm new here so let me know if I should start a new topic.

      Winding pinion making

      By nevenbekriev · Posted

      This is a flying cutter, usual one. The cutter itself is shown in the pictures in the first message, it is made of broken tungsten carbide drill bit. I asure that all the angles of the cutter are as they should be. I have video - little older one - that I made when onse making the same kind of winding pinion for a Poljot 2200, which is even smaller than this one. It is not easy to see in the video, but the tool rest moves about 1mm towards the object in Y direction and then returns back untill cutter is rotating. Then the spindle is rotated one tooth ahead and everything repeated untill all teeth are cut.

      After a bit further research could it possibly be an AS 970?

      FHF70 balance jewels settings

      By Bonefixer · Posted

      Latest project was a non-running ebay purchase with an FHF70 movement. I stripped and cleaned it, reassembled it, and got it running. So far so good, nothing damaged AFAIK.  I was oiling the top jewel on the balance (the one in the cock) which was a slightly unusual shock setting. I removed the spring (3 leaves) which was part of a chaton holding the cap jewel. This left the hole jewel behind which I retrieved with rodico and then lost it. I was taking it off the rodico, very gently as I thought, with tweezers, and then it just disappeared.  Fast forward a week, I got a donor movement, non-running, with the plan to just take the shock jewel that I’d lost. It was the same movement but had standard incabloc settings, and was steel rather than copper/brass.  I changed the cock and balance complete and it ran, not very well. I switched the lower jewel setting, cleaned and oiled both jewels and the replacement balance. Without the pallet fork the balance swings very nicely with a puff of air. With the fork in place, balance out, it flicks side to side nicely with power in the mainspring.  Put them together and it doesn’t run. The impulse jewel sits in the fork and it stops.      Any suggestions how I proceed? In case you didn’t follow that I have 2 FHF70 movements, nothing broken as far as I can tell, but mixing up the balance wheels and jewel settings results in a non runner.

      Oh and this almost perfect third wheel pivot and slightly set mainspring  Ah ok yes i see what you mean, good idea. I'll try that if i fluff this one up. The image isn't great quality but i like the idea though.
