BBC Branded Stopwatch
Whilst not likely to be a primary piece of broadcast production equipment found in a WTBS studio, these production stopwatches were part of a producers tools for the job, so may have been taken with them when they took up their role in one of the Civil Defence Region bunkers.
Swiss made Heuer Stopwatch
A Valjoux 7701 mechanical stopwatch with BBC 1970s era logo.
Measuring 62mm in diameter, they were made for the BBC by Swiss watchmaker Heuer with a CWC mechanism.
Whether they were given individually to BBC producers or formed part of a department's production equipment is not known.
They were used in radio and television production to time audio and video "clips", packages and programme run times.
The serial number was on the reverse.
Now considered collectors items by horologists, they fetch good prices on auction sites. Sorry this one is not for sale!
