TOWER CLOCK PARTS
LUMICHRON has the Tower Clock Parts for Skeletal Tower Clocks (also known as silhouette or marker clocks) and also for Case Clocks (also known as canister clocks). Whether you’re building a completely new tower clock from components or replacing worn parts on an existing clock, we stock commercial-grade tower clock parts and components to meet your needs.
If a surface or wall is to be used as the background of the clock face, we can provide clock hands, movement mechanisms, controller systems, and hour markers customized to your specifications. If you are building a sign cabinet in which the clock will be incorporated, we have the correct tower clock parts and components for that application too.
Custom vinyl clock dials are also available – we always print on CAST vinyl with a special UV coating for superior performance, color saturation, and longevity. Our custom clock parts are manufactured to commercial-grade standards and designed to last for decades with minimal maintenance.
REPLACING PARTS and UPGRADING YOUR EXISTING CLOCKS
If you have a tower clock needing some updates or repairs, we can certainly provide you with modern replacement parts and upgrade components. Many building owners choose to upgrade aging clock systems rather than purchase an entirely new clock—it’s a cost-effective way to extend the life of your tower clock and improve its performance.
The tower clock parts typically required for upgrades include the clock movement (the motor mechanism that drives the hands), new hands to fit updated shafts (we can match or re-use your existing clock hands), or a modern clock controller (we offer a fully automatic clock controller for hands-free operation, often with a GPS antenna for absolute time synchronization).
We can also furnish LED lighting panels to replace old fluorescent bulbs or incandescent fixtures, new crystals or acrylic covers, and new clock faces or dials. If you are restoring a historic clock, we can match the original dial design, or you can choose from our full selection of custom dial styles and hour markers at our Dial & Hand Selector.

UNDERSTANDING TOWER CLOCK PARTS & COMPONENTS
Whether you’re replacing parts from an existing clock or building a custom new tower clock from individual components, here are the essential tower clock parts and what you need to know about each:
CUSTOM CLOCK HANDS
Clock hands are the visible moving elements that display time on your clock face. Lumichron offers custom clock hand designs for any size clock face—there’s no size limit. Custom clock hands can be fabricated to match your specific aesthetic, from traditional spade hands to modern designs, and can be finished in a variety of colors and styles.
Your choice of clock hands affects both the appearance and readability of your tower clock. Longer hands work better for larger clock faces viewed from a distance, while the weight and balance of the hands must be appropriate for your specific clock movement.

CUSTOM CLOCK DIAL & HOUR MARKERS
The clock dial is the face of your tower clock, and hour markers help viewers quickly tell the time. We offer hour marker options including:
- Arabic numerals (standard numbers 1-12)
- Roman numerals (classic, traditional look)
- Simple markers (dashes, dots, or lines to indicate hours)
- Fully custom designs and logos
Custom clock dials and hour markers can be printed on CAST vinyl with UV coating for outdoor durability, or on other materials depending on your application. We can match the style of historic clocks or create completely modern designs.

GPS ANTENNA
A GPS antenna is an optional but valuable tower clock component that keeps your clock(s) in exact synchronization with Atomic Time (NIST). This means your clock will continuously correct itself and stay perfectly accurate—it will match the time on your cell phone and other atomic time sources automatically.
While a GPS antenna is not strictly necessary for clock operation, it’s an excellent add-on for building owners and facility managers who want completely hands-free, maintenance-free timekeeping. The GPS antenna eliminates the need for manual time adjustments and ensures your tower clock is always accurate, even across multiple synchronized clock faces.
TOWER CLOCK MOVEMENTS
The clock movement is the mechanical heart of your tower clock—it’s the motor and mechanism that actually drives the hands and keeps time. Lumichron supplies commercial-grade, heavy-duty clock movements designed for outdoor tower clocks and long-term reliability.
Each clock movement includes a shaft for installation either through a wall or surface, or inset for front access (covered with a decorative rosette). The movement connects via low-voltage (24v) wiring to the clock controller.
Important: You will need one movement for each clock face on your tower. For example, a four-sided tower clock requires four separate movements, all controlled by a single master clock controller.
TOWER CLOCK CONTROLLER (MASTER CLOCK)
The clock controller is the intelligent “brain” behind your tower clock system. It’s responsible for keeping all clock faces perfectly synchronized with each other and maintaining accurate time across your entire installation.
What the Controller Does:
- Powers one or multiple clock faces simultaneously
- Keeps all clocks in exact synchronization with each other
- Automatically resets display clocks after power interruptions (with lithium battery backup)
- Automatically adjusts for Daylight Saving Time changes
- Manages illumination controls (turning lights on at dusk, off at dawn)
- Synchronizes with GPS antenna for atomic time accuracy (optional)
The clock controller operates on standard 110/60 household power and includes a 10-year lithium battery backup for power failure situations. The controller can drift slightly (a minute or two per year), which is easily adjustable by pressing a button—no technician visit required.
LED LIGHTING & ILLUMINATION COMPONENTS
If you’re upgrading an older tower clock, we can supply modern LED lighting panels to replace outdated fluorescent or incandescent fixtures. LED lights offer:
- Dramatically improved energy efficiency
- Longer lifespan (100,000+ hours typical)
- Better light quality and brightness
- Lower heat generation
- Reduced maintenance requirements
NEW CRYSTALS & CLOCK COVERS
We supply replacement crystals and acrylic or glass covers to protect your clock dial and hands from weather and damage. These components help extend the life of your tower clock and keep it looking sharp.
