Mackintosh clock system keeps time in Art School

A unique system of clocks designed by Charles Rennie Mackintosh is to be reinstalled in Glasgow School of Art.

The distinctive square studio clocks, linked to an electrical master clock, were designed by Mackintosh himself.

Time has taken its toll on the clock system and it has taken a year to restore the system to its former glory.

BBC Scotland's arts correspondent Pauline McLean reports.
