Urgos Clock Movement Identification & Replacement Guide
How to Identify an Urgos Clock Movement
If you have an older mechanical clock with an Urgos movement, the first step in finding a replacement is identifying exactly which movement is installed in the clock.
In most cases, the most useful information is stamped directly into the back plate of the movement. Look behind the clock dial or access the movement from the rear of the case and search for a number beginning with UW.
Common Urgos movement families include UW03, UW32, UW58 and UW66, although the complete number stamped on your movement is much more important than the series alone.
Before removing anything from the clock, take several clear photographs of the movement and all numbers stamped into the back plate. Those photographs can be extremely helpful when matching an older movement to the correct replacement.
If you already know the movement you need, browse our Urgos clock movements for available replacement options.
Understanding the Urgos UW Number
The UW number is the primary starting point when identifying an Urgos clock movement.
You may see markings beginning with numbers such as:
UW03
UW32
UW58
UW66
However, do not stop after identifying only the first portion of the number.
Two movements from the same Urgos family can have important differences in their configuration. The complete movement number and the physical specifications of the original movement should be checked before ordering a replacement.
This becomes especially important with older Urgos movements because the exact movement originally installed in the clock may no longer be manufactured under the same number.
Why an Old Urgos Number May Not Match a New Movement Exactly
Many clocks containing Urgos movements have been running for decades. During that time, movement designs and replacement numbering have changed.
That means searching the number stamped on an older Urgos movement may not always produce an identical modern movement.
In some cases, an older movement number has a current replacement or updated equivalent. The goal is therefore not simply to find a movement with a similar-looking number. The goal is to find the correct replacement configuration for the clock.
When comparing an original Urgos movement with a replacement, several specifications should be considered together.
Check the Complete Movement Number
Always record every letter and number visible on the movement.
A partial number may identify the general Urgos series but may not contain enough information to determine the exact replacement.
If the stamping is difficult to read, photograph it under good lighting from several angles. Years of oil, dust or discoloration can sometimes make one digit look like another.
Avoid aggressively polishing or sanding the movement plate just to reveal a number. A clear photograph is usually the better first step.
Check the Pendulum Information
The pendulum system is another important part of matching a mechanical clock movement.
A replacement movement must be suitable for the pendulum arrangement used by the clock. Do not assume that every movement within the same basic Urgos family uses exactly the same pendulum configuration.
If you are replacing an existing movement, keep the original pendulum and record any numbers or markings associated with the movement before ordering.
The clock case also matters. A movement intended for one pendulum arrangement may not function properly in a clock designed around another.
Check the Hand Shaft
The hand shaft projects through the dial and carries the clock hands.
Its dimensions matter because the shaft must properly fit through the dial while positioning the hour and minute hands at the correct distance from the dial surface.
This is another reason identifying a movement solely by the first few characters of the Urgos number can lead to problems.
Two movements may appear similar while having different physical configurations.
Before ordering, compare the specifications of the proposed replacement with the movement already installed in your clock.
Identify the Chime Configuration
Next, determine how your clock strikes or chimes.
Depending on the clock and movement, you may have Westminster chime, a triple-chime configuration or another strike arrangement.
Look at the movement, chime rods and control levers, and note what the clock originally played.
The replacement movement must be compatible with the clock's chime arrangement.
Chain-Driven or Cable-Driven?
For weight-driven clocks, determine whether the weights are suspended using chains or cables.
This is an important distinction and should be confirmed before purchasing a replacement movement.
Do not choose a movement simply because the plate dimensions or movement number look similar. The drive system must match the intended clock setup.
Photographs showing the complete movement, chains or cables, weights and pendulum can make identification much easier.
Do Not Order From a Partial Number Alone
One of the easiest mistakes to make when replacing an Urgos movement is searching only the first portion of the movement number and purchasing the first result that looks similar.
For example, identifying a movement as simply a UW32 tells you the movement family, but additional information may still be required to determine the appropriate replacement.
Before ordering, confirm as much as possible:
Complete movement number
Pendulum configuration
Hand shaft
Chime configuration
Drive system
Physical arrangement of the existing movement
The more information you have, the easier it is to avoid ordering an incompatible movement.
What If My Urgos Movement Has Been Discontinued?
A discontinued movement does not necessarily mean the clock cannot be restored.
Many older mechanical clocks can be fitted with an updated replacement movement even when the exact original number is no longer available.
This is particularly important with Urgos because many clocks still in use today contain movements manufactured years ago.
Rather than searching endlessly for another worn used movement with the identical number, it may be possible to install a factory-new replacement designed for the older application.
A new movement can often be a better long-term solution than purchasing an unknown used movement that may already have significant wear.
Should I Repair the Old Movement or Replace It?
That decision depends on the clock, the condition of the movement and the goals of the owner.
For an especially historic or collectible clock, preserving the original movement may be important.
For many later-production mechanical wall and floor clocks, however, a replacement movement can make practical sense when the original movement has substantial wear or when the cost of rebuilding it approaches the price of a new replacement.
A professional clockmaker can help evaluate the original movement if preservation is a priority.
If the goal is dependable operation, identifying whether a current Urgos replacement is available is often worth investigating before committing to an extensive rebuild.

Need Help Identifying Your Urgos Movement?
If you are unsure which Urgos movement is installed in your clock, do not guess.
Send us a clear photograph of the entire back plate, a close-up of every stamped number, and a photograph showing the complete movement inside the clock. Photos of the pendulum, weights, chains or cables are also helpful.
With that information, we can help narrow down the correct replacement.
