BBC Studio Clock
- Gents' of Leicester
Radio studio clock installed at BBC Broadcasting House, manufactured by Gents. Brass, with a red and green light above the clock face.
Cue lights alert the presenters, performers and technicians whether the programme is going out live to avoid any unintentional broadcast sounds. Green indicates a rehearsal, red indicates transmission.
This clock is part of a system of slave clocks installed at Broadcasting House, controlled from a central master clock via an electrical signal. These clocks provided standardised and accurate time across the entire broadcasting operation. The clocks were installed in every studio and central apparatus room (CAR) to ensure transmissions were timed to the last second.
