Hermle quartz units may die in 7 years or 15 years but when they do die it is usually at daylight savings. Something to do with turning the clocks back or forward then it decides to end its own life. The only solution is to replace the unit with a new one. These are good quality movements and they're made in Germany. They last the average time for a Quartz movement and they sound good, but when they do decide to die it's usually when the time is adjusted. What usually happens is the clock works and chimes but the hands do not advance. There is no fix for this and the movement gets replaced with the same or a different unit all together.
Despite the fact that it eventually dies in this manner, the unit still lasts as long as any other quartz clock movement overall. The reason for this costing more than other quartz clock movements is that it is of German origin and it has one of the best sound qualities on the market. German products always seem to cost more than the Chinese products. Keep in mind you do not usually need to replace the clock movement with the exact same thing, it is just easier as you can use the same hands and the mounting area will be the same dimensionally obviously, as it is the same unit but brand new.
With the numbers the same on the old unit and the new unit, that is most of what is required. The only other thing to measure is the post that the hands go onto, we need to match up the length of this hand shaft. This is measured differently than all other quartz movements as you need to measure the entire length of the shaft from the movement all the way out to the end of the minute hand nut threads. This is the entire hand shaft that sticks out of the movement in one measurement as seen in the picture.
Providing there is space in the clock case for a different movement to fit dimensionally, and you are willing to get new hands to replace the old ones at the same time, you can get any quartz movement to replace this one. If the chimes are not needed, you can spend about $16 for a nice time and pendulum unit with no chime instead of the $89 or $99 for a Hermle unit that chimes. There are other chiming units as well, they are all on the chime / pendulum page instead of this one.

Black metal 3" serpentine style hands. This is a good sized set of hands for a dial diameter of 6 or 7 inches.
To remove the movement you would hold the minute hand still while turning the center hand nut to the left with needle nose pliers. Then the minute hand will just fall off. Then you twist and pull the hour hand towards you and it will come off as it is a friction fit only. You will then see a nut that is holding the movement to the dial. I really do not know why they have designed it this way but it is slotted on both sides. The thing to do is to get a big flat screwdriver on one side and see if you can turn this nut to the left. If the nut is on there very very tight then we have a special tool you can get for this and it does not cost much. If the nut is on too tight you just risk slipping with the flat screwdriver and scratching the dial face. Anyway with that nut turned to the left and off, the movement will just fall out the back of the case. Then you can measure that shaft that the hands go on and get a new unit.
1. Hermle Quartz Battery Installation
Install two "C" size alkaline batteries according to the +/- symbols in the battery holders. If the speaker is mounted to the clock motor, the speaker will need to be temporarily removed in order to install the batteries. Grasp around the outer edges of the speaker with your fingers and pull gently. Care should be taken not to damage the paper center of the speaker. Replace speaker after batteries have been installed and chime selection options are set. The quartz movement in this clock is highly accurate and has been adjusted at the factory for precise time keeping. NO other adjustments are necessary.
2. Hermle Quartz Time Setting
Set the time by turning the minute hand or the TIME SETTING knob (clockwise or counter-clockwise). Never turn the hour hand to set the time, it will turn automatically with the minute hand. When setting the time, the clock will not chime at the ¼, ½, or ¾ hour positions. Additionally, when setting the time using the TIME SETTING knob, the clock will chime approximately three minutes before the hour - this will automatically be corrected during the first hour of normal operation. The correct chiming will start on the next full hour - until then the clock may also chime out of sequence. It is important that the clock movement be allowed to operate for at least one hour for the chime sequence to become fully functional.
3. Hermle Quartz Chime Selection
Use the switch with symbols O,S,W to select the chime according to the following settings: O = Silent W = 4/4 Silent Night melody and full hour strike W = 4/4 Westminster melody and full hour strike
4. Hermle Quartz Autonight / Volume Control
Use the switch with the symbols moon, sun, moon with a slash through it, to select automatic chime silencing or volume reduction. Slide the switch to moon and the chime volume will be reduced for the next 8 hours beginning at the next full hour. Slide the switch to the moon with the slash through it and the chime is silenced for the next 8 hours beginning at the next full hour. Example: Switching to the moon position at 9:10 p.m. will reduce the chime volume from 10 p.m. until 6 a.m. Slide the switch to the sun to cancel the chime volume reduction or silencing.
5. Hermle Quartz Other Features
a) This movement features a 4/4 Westminster and 4/4 Ave Maria chime melody. It plays ¼ of the melody at quarter past the hour, ½ at half past, ¾ at three quarters past, and the full melody on the hour. Slide the 4/4 chime selection switch up for 4/4 melody mode. Slide the switch down to play the full melody on the hour only. The clock will strike the hour in either position. b) Adjust the volume level of the chime with this knob.
6. Hand Installation
Step 7. - If the clock does not start chiming when the minute hand reaches the 12 please do the following:
A. Rotate the minute hand slowing forward to the next full hour until the clock starts to chime.
B. Hold the time set knob on the rear of the movement firmly so that it does not turn.
C. At the same time push in on the minute hand and turn it either back or forward until it reaches 12.
D. Release the knob and rotate the minute forward to the next full hour. If it still does not chime correctly repeat steps A to C.
