Your pendulum weight is out of adjustment. There should be a nut at the bottom of the pendulum bob weight. The weight rests on this nut. To speed up the pendulum, raise the weight by turning the nut; To slow the pendulum, lower the weight. If you are loosing 2 minutes per month, it may require one to two turns of the nut to correct. The adjustment is a trial and error procedure. Keep adjusting until it is right. Shorten the pendulum a bit and then observe the change for one day. A difference can be seen in shorter time intervals when the clock is considerably our of adjustment. I use a digital watch, one that I know its accuracy, and can make rough adjustments in periods as short as an hour. Longer time periods are needed as the adjustment gets nearer to the correct point. Careful: Be careful when adjusting the pendulum. Many of these old clocks have flexural pivots: The pendulum may be suspended by a thin flexible strip of metal (at the top end). This thin piece can be damaged if undue force is applied to it. When adjusting the weight nut, use care not to pull on the pendulum. The weight may hang on the pendulum rod from a hook at the end of the rod. You can lift the weight off the pendulum for adjusting if you wish. One other point: Temperature sensitivity. If your pendulum is not "temperature compensated", there will be a small change with temperatrure. Typically, it will gain about 1 to 2 minutes a month in winter and loose a minute a month during midsummer depending on the average temperature of the clock. How do you tell if you have a temperature compensated pendulum. A plain pendulum made of a single rod is likely not compensated. Compensation is done by using dissimilar metals with different thermal expansions, often brass and steel. Brass expands more than steel. The pendulum consists of a steel rod that desends to near the bottom end and then brass rods asend upward with another steel rod that descends to the bob weight. A properly constructed pendulum can be very accurate keeping time to a few seconds a month. Transporting or moving a clock. The pendulum weight should always be removed when a clock is to transported or moved. This is done to protect the fragile flex pivot and the verge, a wire form that fits over the pendulum and operates the escapement mechanism. The verge is adjusted by bending and can be bent out of adjustment if the pendulum is allowed to move beyond a limit point. Therefore, it is advisable to immobilze the pendulum for any move that requires tipping the clock case.

I have a grandfather clock for sale do not know what it is worth i have called all the dealers in my town and surrounding and i get the same answer hmm idk so no straight answers i know that it is over a 100 years old it is german and there are names on a metal tab on the inside of the door those names are zimmermann&bruckner then below that dresden 1 seestrasse 4 i do have pics that i can send i just need help so if you have any info please let me know thank you

I just went to the Comitti website. Their clocks are really special. We have a Sligh that we purchased many years ago. I like it but never loved it as I felt my husband was too hurried in choosing one and I just wanted to get the heck out of the store as we spent all day and part of another shopping for bedroom furniture, library chairs, and a clock. I wanted a more antique look and really preferred a pediment top to the bonnet top. The Comitti appears to be a peg above the Sligh. I read at one time that the sign of a better clock is the ability to play more than one chime. Our clock plays St. Michaels, Westminster, and Whittington. I would love to see pics of your clock when it's in place!

Jakabedy, some chimes were not pretty to begin with but most of the older grandfathers had much more beautiful chimes than the newer clocks. Newer clocks have a "brassy" sound (craftsman ship has been gone for a while). If, however, you do not like the chime to the point it bothers you, a good clock man can find working parts from old clocks and replace it or even offer you a newer chime that is less finicky. Placing a clock on a soft floor by a draft can also change the sound of the chime. Remember it is recommended you not even wind your clock without clean white gloves to prevent body oils and sweat from touching the intricate working parts, so putting it by a window means all that is multiplied 100 times and could be the reason your clock does not have that melodic sound. If so, then you probably need new working parts. I have all my clocks serviced each December (around the first of the month so I know they are working at Christmas). My musician son has perfect pitch and cannot stand the sound of my 20th century grandfather clock so we turn it off when he is here, but he loves the sound of the older clocks.
