You need to choose a company that has been around a long time and make sure that they are easy to repair. If you look at all of the major clock manufacturers like Howard Miller Clocks, Sligh, Ridgeway and BifanoClockWorks they all use either Hermle, Kieninger or Urgos and all of them have been making them for a very long time. BUT EVEN BETTER Hermle and Kieninger have plants in America so we can use german quality movements made right here in the USA. Of the 3 company's Kieninger was bought by Howard Miller so for the home clock maker that leaves Hermle and Urgos. I would use Hermle because all the clock repair people I know say they are the easiest to repair. They also have more than twice the models available than Urgos.
Here is a Hermle 451-053/94 chain driven movement. These are bigger than all of the other movements. They are either chain driven or cable driven. Here is what the numbers mean. The 451 is a Westminster the 1151 is a Triple chime. The 0 in the 053 says it is a chain driven, the 53 says it is 53 mm long in the shaft. There is a 853 and that means it is a cable driven with a shaft size of 53mm.
