    After looking at the problem of my clock I noticed that the motion of the balance wheel was very limited, approximately 1/4 turn (+ 1/8-, 1/8) and for that reason the tick-tack was too fast, up to 100% more than normal.observing the escapement which is of the type with cylindrical spring I noticed that the movement was restricted because a part of the mechanism was slightly bent and prevent the free movement of the balance wheel. I straighten the bent part and the clock began to work correctly

SOURCE: Why is there two places

Two winding arbours are in clocks with chiming, because there are two separategears in one clock and each one is driven by separate mainspring. Description for winding is: Wind each spring as long as you do not feel significant resistance. As soon as you feel the winding goes too hard - stop winding.

SOURCE: we have a seth thomas

1, Wind the clock. If the pendulum still does not swing, check the hands of the clock. If the hands are touching each other, push the hour hand gently toward the clock face. If the hands still touch, gently bend the minute hand away from the clock face.

2. Examine the swing of the pendulum. If it moves, and then stops, or if it swings erratically, the clock is probably off-balance. Gently tilt the clock to one side and restart the pendulum.
Watch the swing of the pendulum. If it stops again or continues to swing erratically, try tilting the clock in the opposite direction. Tilt the clock at various angles, on each side, and front and back, until the pendulum runs smoothly and regularly.

Note the clock position in which the pendulum swings freely. Place a wedge underneath the clock in the place needed to maintain this angle. If a wedge alone will not hold the Seth Thomas grandfather clock in the proper position, try lifting the clock slightly up against the wall.

Use a screwdriver to attach a bracket to the wall at the appropriate position. Additional brackets may be needed depending on the angle required. It may also be necessary to employ a combination of wedges and brackets.

SOURCE: i need to know how

Hi ajhazel1,

Please follow the steps below on how to set the alarm on your seth thomas mantel pendulum clock.

1. Determine if your Seth Thomas mantel clock is a 7-day clock or an 8-day clock. On most models it will say right on the face of the clock which type it is. Seven-day clocks must be wound every 7 days, and 8-day clocks must be wound every 8 days. If you are unsure you should wind your clock every seven days.

2. Look on the back of the clock. You will see three large holes (just large enough for the clock winding key to fit into) plus one or two smaller holes (often just large enough for the small end of the key to fit into). The two smaller holes are for speeding up or slowing down the clock and for turning the chimes off and on. The three larger holes are the ones we are interested in--they are the ones we will need to wind every 7 or 8 days. On some models the three winding holes are on the front of the clock. Winding instructions are the same, regardless of where the winding holes are located.

3. Push the large end of your clock winding key gently into the hole on the right as you look at the back of the clock. This hole allows you to wind the 15-minute chimes. Gently turn the key clockwise. Keep turning it until you feel resistance and the key stops turning. Remove the key.

4. Insert the large end of your key gently into the center hole. This hole allow you to wind the main clock mechanism, which allows the clock to run and to keep time. Turn the key clockwise firmly but gently until you feel resistance. When the key no longer wants to turn simply remove it.

5. Insert the large end of the key into the hole on the left. This winds the hour chimes. Turn the key clockwise firmly but gently until you meet with resistance. When the key no longer turns easily remove it and place your clock back on your mantel. Your clock is now set to run for 7 or 8 days, depending on the model you own.

6. Use your hand to start the pendulum swinging once the Seth Thomas mantel clock has been set to the right time. The pendulum should be located in the back of the clock. The clock will not keep time if the pendulum is not moving.

Hope it helps.

Thank you for using FixYa.

Coaster model 900723 grandfather clock doesn't keep time

Everybody should know that the coaster clocks discussed here run on batteries. The timing mechanisms, the chimes as well as the pendulum all are powered by a battery. Changing the speed of the pendulum is impossible because there is no adjustment. Besides, it wouldn't matter anyway. The pendulum has now affect on the clock's ability to keep accurate time. It is purely aesthetic. This is a pretty cool looking clock and even has weights, but those are also purely aesthetic and do not move the way a classic grandfather clock weight would move. The moments with these clocks are not designed to be worked on. These clocks are relatively inexpensive (approximately $300) but do add a nice look to your home. Grandfather clocks snobs would say though; this is not a true timepiece. They're right... Sorry._1513.jpg

You can not unwind the clock yourself, because this requires proper clock makers tools and skills as well. Clock is stopping because it has not been serviced for a long time and the oil in clock has collected dust particles and getting sticky. This does not let the spring unwind freely and is a problem for all cogs and moving parts. Find your nearest clock repair shgop and ask for cleaning, oiling and adjusting. BE AWARE: If you are gonna try to unwind it yourself, you will damage the clock's movement, but most important - you can even brake or loose your fingers, as the clock spring is under unbelievable tension and once released, it uncoils lightning fast and is sharp as a razor.

Setting the correct time on Seth Thomas clock.

Correct technique definitely is CLOCKWISE ONLY. You are unbelievably lucky person if did not damage striking mechanism within 25 years while adjusting hands anti clockwise. If I'd have such a luck, I'd try to play lottery. :))

I purchased an old Hamilton mantel clock that did not run. I have cleaned and oiled it and now it works well except it losses five minutes per day. This has a German movement, spring escapement type,...

This clock has a floating balance escapement.

Hold the balance snuggly with 2 figures. Take a small screw driver and push one of the 4 legs above and attached to the disk to the "+" direction. Move it about 1/4 turn. Set the correct time and check again the next day. If the clock is still slow, move it again and set the hands. Do this until the clock is accurate.

Disclaimer: If this movement was made in the 1970 or early 1980's (The date is a 2 digit # above the movement model number). Those years the clock manufac. (Hermle) did not do well in quality materials. The may need an overhaul or movement replacement. I can provide more information if needed.
