What makes us different

Precision from the source — not just a display

A clock is only as accurate as its time source. Our GPS clocks sync directly to satellite signals — accurate to milliseconds. NTP server clocks sync to your network time infrastructure. Master-slave systems let one GPS or NTP master drive dozens of slave displays across a large site — one source, perfect synchronisation everywhere. We manufacture to any digit size, any number of time zones, any display format.
