I HAVE TWO MECHANISMS ALIKE THIS. THIS IS FOR LISTINMG NUMBER #1.
Clock Movement Hermle 351-030 AH 75cm. Clock mechanism not that old. This one is newer than the other I am listing. When I got out of box the Chimes were working well. I installed in Clock Case. Worked for a day or so but stopped working. I tried everything. I put side lever in all position no lock. Clock does work and keeps great time. Comes with clock hands and key. Does not come with pendulum. Just showing on video that mechanism works. Comes with key. Key is used. Clock hands measure 2 1/2" Smaller Hand, and 3 1/4" for larger hand. When I bought mechanism, it did not come with key. See 2 videos below to see mechanism working:
See another video to show the clock was dinging out of box, but stopped:
