Newgate Street Clock

Audemars Piguet wandering-hour watchA new clock is being unveiled on May 31. It uses a “wandering hour” dial, in which a pointer moves along a scale of minutes. The pointer is marked with the hour, and as it sets past the 60-minute mark a new pointer rises, with a new number.

Some Audemars Piguet watches use the same principle.

The clock was designed by Joanna Migdal (here is her web site, which wasn’t working on May 28), who designs sundials as well as clocks and has also done work for the Worshipful Company of Scientific Instrument Makers. The clock was manufactured by Smith of Derby, “one of the very few English manufacturers able to handle the ingenious modern mechanism”, although evidently they don’t trust themselves much, since it has been designed so that its working will be corrected by satellite radio signals.

The clock is the gift of the Worshipful Company of Clockmakers, who have a museum in the Guildhall.
