Clock movement 1151 Series by Hermle
Hermle clock movement 1151 series is a triple chime unit. It is the most produced triple chime, chain driven unit ever made. These clock movements can work night and day for 30 years sometimes without a sweat. The customers who order this movement originally purchased there clock in the 1970's through the 1990's.
The movement
Hermle clock movement 1151 series are all square movements. The are all with a 120mm plate size and in triple chime. The hand shaft length was made in two different lengths. The 1151-050 has the 32.3mm hand shaft while the 1151-053 has the longer 53.2mm hand shaft. The unit is a triple chime movement and is always chain driven. There are 12 hammers on the back side of the unit with 4 on one side and 8 on the other side. There was a time on these units that it came with a calendar function but these are not common. This is the same unit as the 451 series but with triple chime instead.
Does not come with
It will not come with the dail, chimeblock, weights or pendulum. All these things we have available, but if ordering the movement only, you are ordering the movement and not the complete kit.
Comes with
The movement will come as the same movement, no knockoffs, made in Germany. The unit will be already oiled and will come with instructions and support. Basically everything that comes out with the two screws underneath, that entire gear ball with its hammers attached. The movement will come with new chains, its leader, hand nut and suspension spring.
The chime songs
This is a quarterly chime unit that will play a song every quarter hour, and then at the top of the hour it will strike out whatever hour it is. The song options are Westminster, Wittington, Saint Micheal. None of them have the autonight shut off feature but does have a silent option within the chime selection lever.

I have a friend who acquired a Franz Hermle clock 1151-050H a few years ago and I have some questions that you might help me with. I got it running but it stops after a few minutes. The chimes don’t work; Or maybe it has night mode auto off??? Did the original CM have that? Also how does one change the chime sounds? I want to replace the CM after I try a clean and lube.
That one does not or ever did come with ANSO, so there is some other issue with the chime.
Please run it without the hands and the clock dial for testing the chime. It will narrow things down. Next, put the minute hand on just slightly to turn it to the next chime, and the next, let it strike out the hours fully. If it chimed and striked ok, your all set, put the dial and hands back on. What happened is the rack fell behind the snail (the hour hand tube) and brought it forward some. It brought the hour hand forward to the point that when the minute hand is installed it squashed the hour hand upon tightening the minute hand nut. With the strike squashed between the front plate and the snail, all sorts of weird issues occur. If this was a fail and the clock did not chime through this, continue with the below check points.
Be sure the clock’s silent lever is in the down position. This lever is at 3oclock on the movement. This is chime ON.
The chain cant be rubbing anything in its path like the seat board. Should be ratchet wheel straight to the weight, not rubbing anything.
Is the hammers hitting anything in its path when they move? If the hammers are rubbing the back of the clock case, or if there hitting or rubbing against each other, the clock will hang up and not chime
The heaviest weight on your right as you face the clock? The chime weight is the heaviest weight out of the three and goes in this position.

CM is just a measurement for the approximate pendulum length = Centimeter

My dad died three weeks ago, and I inherited this clock. I got it running and keeping time, but it will not chime. I have moved on off swtch to no avail.
Very sorry to hear about your father. To help with the chime, we need the movement numbers off of the back plate of the brass movement itself please
