Last week I had the chance to aquire this lovely Kienzle with IMHO one of the most beautifull pendulums in excellent condition. And : No,no ser.number on the underside of the pendulum.Interestingly the regulation weights are marked F/S on one and A/R on the other.Enjoy!

How lucky can one be? Very unusual and, as you say, beautiful pendulum. Would love to see it in motion.

Hi Burkhard,

Looks like a nice addition for your collection. Counting your clock I've only recorded nine with that mercury pendulum, eight Kienzle and one Becker which I'm sure was a marriage. Is your pendulum missing the bottom cover or just unmarked? Kienzle was really good with stamping movement serial numbers on their pendulums.

the pendulum has kept its bottom cover which looks original,not aftermarket ; just plain,without marks or numbers.My Kienzle calender has a pendulum with (identical) serial number stamped in.What´s about the others,are they all numbered?

Hello Berkhard,

The mercury pendulum that I have is very similar to yours except for the difference in the edge of the pendulum disc, mine does not have beveled edge that is found in yours. On my clock the serial number of the mercury pendulum ( 129238 ) is not the same as that found on the back plate of the Kienzle movement ( 125054) . The wooden base is a replacement.
As can be seen in the pictures below, the pendulum is in exceptionally good condition overall.
The glass tubes containing the mercury are very clear throughout and the mercury remained shiny with very little noticeable sign of oxidation.

Burkhard,

I cannot say that all disks were numbered, but from what I've observed they were very consistently numbered up until serial numbers around 150000. All of the clocks I've recorded below 150000 where the bottom of the pendulum was shown have a serial number stamped into the bottom cover. The beveled edge disk doesn't show up in my records until after serial number 139000. All disks I've recorded prior to that have squared edges like Mun's shown above. From this I would say your disk is from a later Kienzle clock.

One of my goals is to acquire examples of all the compensating torsion pendulums. I had bid on an ebay auction some time ago for a Kienzle clock with the mercury pendulum such as yours, but the pendulum drove the price up about $900. I hope you got a better deal than that!

Hi Burkhard
How great to come across one these more unusual pendulums. It is one I have always dreamed of coming across, but have never even seen it. Enjoy it and thanks for showing it to all of us.
