  • This video is a run through of how to set the beat of a Hermle mechanical clock.
    in particular, the mechanism is a Hermle 451-050H.

    So ... what are you actually doing by applying the pressure? Are you looking to bend the linkage above your finger pressure point? There's a thin metal 'hinge' at the pivot point at the top? Is it this that you're trying to influence?

      There is a pressure clutch that is spring loaded at the top of the anchor assembly, where it attached to the crutch lever I’m applying pressure to. In this case it’s not so much bending as it is by forcing the anchor to slip relative to the angle of the crutch rod/lever. Hope that helps clear it up?

      If it's OK, I'll continue the discussion via e-mail, we'll be able to refer to my pictures, and we'll work from there.

    How do I do this without the equipment you are using?

      You can use your 'ear' to hear if it's markedly off in one direction or another. It's not as accurate as the meter but it will suffice. It 'limps' either loooong--short, loooong--short, or v.s.v "short--loooooong, short--loooong..." It's a tug of war (as we see in this video,) to get it near perfect at which point it's escapement is most efficient but it's worth trying a bit of patience to get it close to even. ALL part of the fun of owning these beautiful and well designed clocks. It's funny - I sleep in the same room as my Ridgewood grandfather clock and if the pendulum is even I sleep right through it but if it's limping in any amount one way or the other it keeps me awake! So, one could say I CAN'T REST till it's nearly perfect with an even tik-tok.

      well said. like typing a description of lacing shoes, difficult to describe but you nailed it.

      I can't vouch for this myself, but I read a clock video comment elsewhere where someone used a metronome app for one's phone (metronomes are typically used with pianos) and that some of these apps can "listen" and determine if the beat is a match for the metronome timing.

      @@bobsquires4521 What does it mean if one can hear the "tick" but not the "tock" of a clock that keeps stopping? The clock is a Hermle Franz 351-020 (45cm) wall clock, which came from an elderly family member's home (likely not transported correctly but also not known to be working for the past seven years, regardless). Spouse and I tried cleaning and oiling the pivot holes but there was no improvement. How does one know if the pendulum stops because it is seriously out-of-beat vs. another cause? (For example, the Westminster Chimes only go off at the 3/4 hour mark and at that point they overlap with strikes). In essence, how does one know if the beat simply needs to be set or if the movement is damaged?
