The largest timepiece had a clock face area of 8.42 km² (3.25 mi²) and was created by Jim Bowers (USA). It was measured at the Burning Man festival in the Black Rock Desert, Nevada, USA, on 5 September 2011.
The clock was created with the help of lasers and "hour towers" that were set up in a circle around the laser at the centre. The average length of a laser clock arm was 1,636.8 m (1.02 miles) long. It took 13 months to create the clock. It was used to count down the hours until the burning of "The Man".
