It seems like a good number of years have passed since the test pattern was used on TV. Due to advances in equipment such as digital signalling, better televisions and most TV channels broadcasting 24 hours the requirement for test pattern is just not there any more. The test pattern clock is built to bring back the memories of late night TV. Luckily the annoying beeeep is not present in this clock. I have to admit that it looks like a fairly cool clock. Surely all you from little old NZ remember this test pattern with fond memories of years gone by. So go ahead and pick up one of these Test Pattern Clocks to bring back the memories. Great as a gift for Christmas, Birthday or really any occasion! The clock is glass and measures 43cm.
