1. Chime type?
There are two chime types, Westminster chime only, or triple chime. The Westminster with just have chime or silent at the 3 O'clock switch, and the triple chime will have your choice of three songs and also silent at the 3 O'clock switch. If you have no switch at 3 O'clock, its Westminster only.
2. Weights hang on?
There is only two options for this. Either the weights will be hanging on chains coming down from the movement, or the weights will be hanging on pulleys that are hanging from cables. The chain driven units get wound up by pulling down the chains, the cable
driven gets wound up by a crank key that gets inserted into the dial holes.
3. Hand Shaft Length?
This is the measurement of the shaft that the hands go on, from the front plate of the movement and all the way out to the end of the minute hand nut threads. This is in mm but you can convert to inches online if you need too. Just type into a google search mm to in. The options are displayed on each movement series so all you have to do is figure out what mm length yours has that matches.
4. Pendulum length from top?
The Germans measure the pendulum length from the top of the movement and all the way down to the bottom of the pendulum nut threads. This measurement is approximate and varies depending on bob diameter. (The bob is the round disk at the bottom of the pendulum). The larger diameter on the pendulum bob, the longer the pendulum is needed to be for the same unit. The Germans base there PL length (sometimes stamped on the movement, but usually not) on a bob diameter of 4 1/2 inches. (4 1/2 inches = 145mm). So when the list says for example 93cm, they are talking about the pendulum from tip to tip, the pendulum leader that is hangs on, and the suspension spring that the leader hangs on. All three components put together in one measurement in CM's.
If this is confusing, we can do this another way. If you take off your pendulum, and put it on the kitchen table, and measure the pendulum from tip to tip when it is off the clock, we can say this instead=
- If the pendulum Length 27-30 inches, get the 80cm movement
- If the pendulum Length 31-34 inches, get the 93cm movement
- If the pendulum Length 35-37 inches, get the 100cm movement
- If the pendulum Length 38-40 inches, get the 110cm movement
- If the pendulum Length 40 plus inches, get the 116cm movement
The three weight square Urgos clock movements are known as UW32 series. There are some other numbers on the back of the clock movement, but please ignore them. Such as your movement may say UW32319 or UW32/1 or anything else, but all we are concerned with is you have a UW32 series.
We only need to know if its Westminster only or triple chime, what the weights hang on, how long the shaft is that holds the hands, and then the pendulum length. Please note the directions carefully as it explains how these measurements are to be done. When you have the information, just click the options in the drop down menu and wallah, you have a new movement coming to you. It will be the same unit and be able to fit your other clock parts such as weights and pendulum and so forth. The movements come already oiled and includes the chains or cables with pulleys.
Plug and play? Almost, but there are some things to do, and instructions will be emailed to you. If you get stuck just call or email.
It is easy to put this one in and swap out the old one. After you get the hands and the dial out of the way really there are only two screws underneath that hold the movement in there. All the other stuff hangs off of it. The instructions explain all this, and if you get stuck you can just call or email us. With over 100 years of combined clock experience we can help with whatever you have going on.
So there it is, a new movement ready to go in a week, for about 1/4 to 1/2 the price of an overhaul. German made, no knockoffs, ready for another 30-40 years of service. The movement comes with its chains or cables / pulleys, its already oiled, tested before shipping, comes with the leader and suspension and instructions.
