Features
Everything a tower clock needs.
One controller for clockwork, sound and light – set up in a clear web app that runs on any smartphone, tablet and PC.
Bell strikes & melodies
Quarter-hour chimes, hour strikes and melodies before or after the full hour – with night silence, volume per sound and festive ringing at the push of a button.
Bell schedule
For schools and businesses: break and shift signals to the minute by weekday, series created in seconds, holidays as exceptions.
Your own sounds
Simply upload MP3, WAV and more – the app converts everything to fit. Your own recordings stay on your clock, not in the cloud.
Dial lighting
Automatically at dusk or by light sensor, with night switch-off and atmospheric light effects for special occasions.
Control from anywhere
All your clocks in one app: set the hands, test sounds, change settings – with confirmation as soon as the clock has applied them.

Whether a historic church clock or a signal clock in a factory – Clocktrol adapts.

How it works
Three steps to a smart tower clock.
Install
The Clocktrol controller is connected to the existing clockwork and drives the hands with its pulses – the clockwork itself is kept.
Connect
Online via Wi-Fi or network cable. With the pairing code shown on the display you link the clock to your account.
Set up
In the app you choose sounds, bell schedule, night silence and lighting. Done – the clock takes care of the rest.
Security & reliability
Built for decades in the tower.
A tower clock is public – so it must listen to you only. Clocktrol is secure by design.
- Security chip in every device: commands and software updates are cryptographically signed.
- Keeps running without internet – with its own time and the stored hand position.
- Security updates for at least 5 years, installed automatically when no strike is due.
- Privacy-friendly: servers in Germany, no ads, no tracking.
Questions & answers
Good to know.
Does Clocktrol fit my clockwork?
Clocktrol drives clockworks that are advanced by electrical pulses (e.g. slave clock and minute-pulse movements). For other movements we are happy to find a solution – just ask us.
What happens during a power cut?
The hand position is stored permanently. As soon as power is back, the clockwork catches up the lost time automatically – no intervention needed.
And if the internet goes down?
The clock keeps running on its internal time and plays all sounds as scheduled. Once the connection is back, it syncs the time again.
Can I manage several clocks?
Yes. All clocks appear in one account, you switch between them with one click and can copy sounds from one clock to another.
Where are my data and sounds stored?
Account and settings are stored on servers in Germany. Your own sounds are only stored on your clock's memory card – our server merely passes them through.
How much does Clocktrol cost?
Every clock is different – we are happy to prepare an individual quote including installation. Write to us or give us a call.
