Look no hands as Sydney's GPO clock gets a makeover

It is Australia's largest mechanical clock and was considered so important that it was dismantled during WWII for fear Sydney's GPO timepiece could become a target for enemy aircraft The problem with the GPO Building clock at the Fullerton Hotel at 1 Martin Place is that all is not as it seems No more will that be the case as work began on the clock on Wednesday as part of a major refurbishment.

Made by JB Joyce in the UK and installed in 1891, it is a three-train flatbed clock with gravity escapement and once the makeover is complete, Westminster chimes: four bells to the chime and another for the strike just like Big Ben Remediation work will include removing, glazing, repairing and reinstating the clock glass External stone and metal work will include intricate clock frame repairs as well as lead weathering and waterproofing.

Once complete Mr Markerink said the clock will be as accurate as the GPS on a smartphone. . Source
